I have a Gateway laptop and it has completely died and will not turn on. I noticed that when it died the AC adapter was making a clicking noise so I figured I would replace the adapter to see if that was the problem. I have replaced it but the new one also makes the same clicking noise but only when plugged into the computer (as was the problem with the old one). I know the AC adapter is giving sufficient power but the computer is not taking it. Any suggestions as to what it could be or how I can fix it? Detailed directions on how to fix it would be appreciated as I am no computer whiz. Thanks in advance!

A:Power Adapter Clicking and computer dead

I don't know anything about laptops...but isn't there a power supply inside that the ac adaptor plugs in to? I imagine there has to be. Well I have seen, and smelled, (and heard) a few power supply units blow up. Often times they make a clicking noise. This is how it is with desktop power supplies but they have to be similiar to a laptop power supply. *(If laptops don't use a psu, please disregard this).

With or without the AC power adapter plugged in to the computer (known good power outlet), the computer will not power up.  The LED located on the left side of the computer where the AC power plug is connected flashes 3 times (white), but does not power up.  Other post I saw said 'continuous' flashing light would be the AC power adapter, but wanted to make sure that is actually the problem before purchasing a new one...  Any support would be awesome!

Hello fellow Thinkpad users, It appears that the 170W power adapter of my lenovo ultra dock just died. I can not charge my computer, neither directly neither via the dock. However, if I use my other 170W adapter supplied with my W541, both the dock and the laptop work. I have my dock serial number sucessfully recognized by the warranty check tool on lenovo's website, however, when I try to file a case, the system can no longer recognize my serial number. The dock was bought from the UK, do you know any Lenovo representative which I should contact. Very much appreciated for any input. Cheers,Deyan

I'm In a dilemma with An Emachines T2792 I received the pc from a friend whom knows I work on PC's on the side when I plugged it in I found it to be stuck turned on
The green indicator light was lit like it was turned on, but no signal was stated on the monitor,, then after trying unsuccessfully to press and Depress many times did nothing
so I unplugged and replugged in the same, so I unplugged again, and messed with button some more then replugged in , nothing no green indicator light then i noticed a soft whistling and clicking sounds from power supply, so I got another brand new power supply {correct power supply} when I plugged tower in it lit the green indicator light on tower then softly went out
I tried pressing in power button nothing no response.
Now my question is I am pretty sure I need to buy another power supply now
But I need some ideas on what to replace to get the pc up and running again??
would it be the switch???
or the motherboard????

I had a similar problem with an emachines T2825. When I plugged it in, it automatically came on, and wouldn't turn off unless I unplugged it. It wouldn't POST or anything. After testing everything, I found out that the motherboard was bad. So that would be my guess, is that it could possibly have a bad motherboard.

I'm working on a 10-yr old HP pavillion pc. The pc would not turn on at all, monitor displays 'no signal'. the pc lights flicker. I had an older atx power supply and tried that- it worked. so I know that the old power supply was bad. the case was VERY dirty. almost all the vent holes were clogged. even after I tried my 'new' power supply, the cpu fan does not come on and I still get 'no signal' on monitor (the hard drive/cdrom drive DO come on). I'm thinking the power supply blew, taking the mobo with it. I don't want to spend alot of time on this, but can anyone offer any thoughts on this? thanks.

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

I need a cross reference for these kinds of numbers.

Kensington referred me to their telephone tech support; but, there is a language or cultural barrier that prevents their understanding what I need.

Does anyone know of such a reference?

My laptop will no longer turn on.  When the AC adapter is plugged in, the LED light is white indicating power is arriving at the laptop. However, nothing happens when I push the power button. Troubleshooting steps I have completed already include: Hard reset (several times including after each step below)Tried starting without the batteryRemoved all removable components and reseated themRemoved all removable components as well as bottom cover. Cleaned with compressed air. Put everything back.Nothing appears wrong and nothing happened between the last time it turned on and this time that I am aware of. The laptop is out of warranty, and I am pretty handy with computers. Is there anything that can be suggested short of a hardware replacement that would help get this resolved? TIA

This is a common problem (I see lots of posts)
The problem source is the [Dell] AC adapter.  PA-21 Family, 65W, P/N: NX061.  It is made in China.
I have an XPS M1330.  Using Dell after warranty service, replaced the Mother Board twice, replaced the battery twice, replaced the AC adapter twice - not fixing it.
Turns out the power warning message is very informative.  It states "Please connect a Dell 65W AC adapter or greater for best system performance".  So, I plugged in my Dell 95W adapter - WOW Problem Solved.
A lab test of my new Dell 65W AC adapter shows it to be 64.6 watts.  If this unit gets hot (like after several hours of use), it may not put out the full 65 watts - the system may not recognize the adapter, it may power the system ok, but won't charge the battery.
These units burn out after only a few months of use. Their cables are too fragile. If Dell's or their supplier's Quality Control can't produce a reliable 65W product - I found seveal "Made In USA" universal adapters.

A:AC Adapter - Alert - "AC power adapter wattage and type cannot be determined"

Well my solution was simple.
I just removed the battery pack and powered up my notebook. Then I turned off the notebook replaced the battery pack and VOILA. The error message was gone.

I assume that my power supply has died on me. When I try to start my PC I get no power except the green LED light on my motherboard. I have noticed when I had my case open that when I push the power button on my case that all the fans in my system slightly turn but thats it, even the cooling fan in my power supply. The power supply is a 300 watt ATX and I wonder if I was underpowering my machine. My mother board requires a minimum 230 watt power supply and I have my hard drive, floppy drive, dvd-rom and cd-rw along with the motherboard and all of the cards pulling power off of the PS. My dvd-rom had quit working over a year ago, it would freeze up on me whether I tried watching a dvd or doing a data transfer. Also, I would have to push the open button on my cd-rw 3 or 4 times to get the drawer to open. I suspect that I may have been underpowered for the hardware I have.

Anyway, is my PS dead and if so, what should the minimum wattage I should get for the hardware I have? Thanks in advance for any replies.

I just bought a Raidmax 735W LED ATX 80 Plus Bronze Certified Power Supply at Frys tonight. I haven't installed it yet, but when I inserted the power cord, plugged it in and turned it on, nothing happened - no fan, no light. Is that normal? Does it only kick on once it is attached to the motherboard and computer devices? Or did I get a dud? I don't want to go to the trouble of installing it if it is a defective unit.

I started my PC this morning and it booted as normal then after 30 second or so it turned off. I tried to start it and got nothing at all. I could smell something like an electrical burn. I pulled the power supply and put a jumper between the green wire and a black wire and the PSU did nothing. I had a smaller PSU not being used so I tried the same thing with the jumper and it started right up. So it looks like my PSU is dead. I hooked the older one that was working to the motherboard and got nothing again when I tried to start it. I am wondering if a power supply goes could it have taken other hardware with it?

The PSU and processor are 6 years old. The memory is 2 years old. The motherboard is 4 moths old.

A:Power Supply Dead?

Yep, if another PSU booted the machine, you have a dead power supply. I'd look at replacements with the same Wattage rating, but spend the money to get a good quality replacement, and don't buy the cheapest possible PSU. A crappy power supply can fry your system if it fails. You are much better off spending some extra bucks on a highly rated power supply than buying a cheaper unit that claims to have a higher output. Antec, Seasonic, Coolermaster, Thermaltake, Corsair, OCZ/PC Power and Cooling, and Sparkle are good brands. I'd avoid Rosewill, Diablotek, Xigmatek and "budget" power supplies in general.

We had a storm roll through late last week. Long story short, my pc was dead. Hitting the power button had zero effect. No lights no fans no nothing. I swapped outlets with the same result. I swapped power cords with the monitor, which was working, and the pc still didn't power up and the monitor powered up with the pc power cord. That narrowed it to internal to the pc. I put the hard drive in another machine and can view everything, so thankfully the hard drive is good. My guess is the power supply. Does that sound like a good guess to you guys?

It is a Dell Dimension 2350. I have heard and read that Dell ps are proprietary with a unique plug. The articles that I have found though are several years old. Is this still the case? I compared it to an HP machine and aside from the physical shape, the connectors look to be the same. My question, is will I be able to buy any brand ps and swap it out, so long as it fits this case?

Thanks a ton for any insight and info,


A:Power Supply dead...I think

you would have to make sure that the mobo and psu conform to ATX form factor, the plug that goes into the motherboard has to be ATX 20-pin, and of course your power suplly has to match the ATX ones in the local pc store, if I were you take out your dead one and bring it with you when you go looking.

Alright so the story first, last night all of a sudden the screen went black and the computer didnt make any noise at all, so i thought that it just power'd down. then i tried to turn it on and nothing happend. If i unplug my computer for a while and plug it in then there will be a green light on the back next to the power supply, when i try then to turn it on it the MOBO fan spins then it all stops and the back power supply light turns off. then i hold down the power and after a cupple seconds the light on the back will come back on and i push on again and it just spins the fan and shuts off. im hoping its the power supply.

Normally the power button on my computer is lit up blue when the computer is on and it slowly flashes blue when it is asleep. I tried to turn on my computer today and the power button is more quickly flashing yellow and I do not hear the power supply. I purchased this COOLER MASTER GX Series RS650-ACAAE3-US 650W ATX12V v2.31 80 PLUS Certified Active PFC Power Supply over a year ago. It is plugged in and the switch is to the on position. Has it died?

A:Is my power supply dead?

It's a good guess but only that. I would open and inspect all connections, blow out PSU and case completely, while case side is open I would watch and listen as you start up. Then get back to us with any error lights on mobo, sounds and the like. Can you find a friend with, beg, steal or borrow another PSU?

Hi all,

I'm a new boy to the forum but would be grateful for your help on a problem that has suddenly developed on my son's machine. I have some knowledge but not a lot (what's that they say about a little knowledge being a dangerous thing..)

Anyway the problem is as follows:

The system was bought from novatech in the UK about 4 years ago. It is 2000+ AMD processor on a K7SA5 motherboard running XP home.
All was fine at lunchtime.
When switching on this evening, the fans (graphics, CU, case, PSU) start, the power LED, HDD LED and CD LED all come on (and stay on) but nothing else happens. Normally there would be one beep and the system would start. Now no beep, nothing.
The power switch and Reset buttons now do nothing - need to switch off at the wall.
I've check some of the power leads and they seem to be sending out 12V and 5V OK.
There have been no general power problems that I am aware of eg surge/ spikes, other machine in the house are fine.
I've checked the CMOS battery and reseated the cards and memory.

My guess is that the system isn't even getting to the motherboard ROM to start up the POST.

Could it be the PSU?
The Power Switch?
The Motherboard?
Any thing else?

Any pointers gratefully received.

I'm not keen to change the MB unless I have to as the PSU is only 300W and any newer stuff is likely to need that upgrading too - I might end up with the costs of nearly a whole new machine.

A:Is my MoBo dead or is it power or something else?

Same thing

My computer is doing the same thing, except, I switched my hardware from one case to the other and power up was attempted, a fan would spin, a led would pop on and nothing else. I switched back to the original case and the same thing happens. The RAM led is lit on the motherboard and network port is lit and flashing so I know the MOBO is getting power, but it just does not want to power on the whole way. I had the same problem when I first built the box, but it was resolved by another friend when I wasn't looking and I neve asked the technical details on how he fixed it. My specs are below.

MOBO: Gigabyte GA-8IPE1000 Pro Intel P4 3.0G HT
VC: ATI Radeon x800 PRO 256MB AGP
PSU: Turbolink Switching Power Supply (stock with full tower)
Memore: 1.5G of Corsair Value Select and HP stuff
HDD: Seagate Barracude 120GB

I have fooled with the front panel wiring to see if that is the problem. Tried powering on sans video card, soundcard, HDD, fans, etc. I am completely lost. Cleared CMOS as well.

Any help/advice would be greatly appreciated.

I went away for a few days and had shut the system off while I was gone. When I got back, I turned the system on and the power supply fan won't run. I'm using the system for very short periods trying to do some important stuff like making a startup disk (procrastinated far too long I know!) The question is this, can this be fixed, or should I just buy a new tower with a new power supply? My current tower was from the 386 that my system was originally (now it's a 300Mhz with Win'98SE).

Just to clarify further, when I turned it on to come here to ask the question, it booted with a CMOS checksum error and I had to reload all of my BIOS settings, auto detect harddrives, CDrom, everything. I'm assuming that was due to the complete failure of the system resulting from the loss of the power supply fan (and the dying breath of the CMOS battery which I know needs to be replaced since it loses time when turned off).

A:z510 is dead. No power. Need help!

Obviously you can't recover data from a dead laptop.  You would need to remove the hard drive to do that, but then warranty issues arise.  In reviewing the User Guide for your model it is pretty limited on what the Owner can do unlike other laptops.  The only option I see to resolve your problem is to send the laptop in for warranty service.  When sent in I would point out to support that you need the data on the drive both verbally and in writing.

Hello, I have been using a home-built computer for about 2 years now. It's been working fine, no problems. However, today, I was unable to boot it up. Do I have a dead power supply? When I turn on my surge protector (which has my computer, as well as my moniter connected), it seems as if everything works fine. My monither turns on, and my computer's modem light (on the back side) turns on. When I press my power button, nothing happens. I looked inside my case and there is a light on saying that my DIMM is functional, so it seems there is SOME power..but when I hit my power button, I see my CPU fan spin once, and then stop moving. WHenever I hit my power button after that, I get no response.

Is it time for a new power supply? Or could there be another symptom?

By the way, the power supply I bought CAME with my case..

A:Is my power supply dead?

Well it could be the power supply, or the front case power switch, or the motherboard, or another faulty component.

But you need to start somewhere. Youll have to either have the power supply tested or you'll need to get a power supply to test in your system.

I just installed a CD-burner. Once I got everything put together I hit the power button and nothing happens! I assumed I had knocked something loose but I can find nothing. I installed this Mother Board so I know it pretty well. I can not figure out what has happened.

The only clue is that when I hit the power button I hear the familar pop of the speakers. The fan on the CPU twitches and that is it. Any clues as to what is going on? I am leaning toward a bad power supply but the fact that I just installed this CD-drive really makes me wonder if it is somehow related.

BTW I have tried unplugging everything to see if one of drives might be responsible. Double checked all conections and all the obvious things.

I am open to ideas!


A:Dead power supply??

I would agree kudzu. Your computer shows the same symtoms as a computer I replace the power supply in about 4 months ago. Most likely a burnt out capasitor.

As long as it burned out because of age and not because of a hardware falure, I think your safe.

Hi all, first post on here.

Did my first self build last week with help from a friend.

600W EZCool PSU
1024Mb nVidia GeForce GTS 250
Intel Core 2 Quad 8300 2.5GHz
320Gb + 80Gb Hard drive
Windows 7 64bit

Built it last week and its been having problems powering up. Sometimes it doesn't start when I turn it on at the front, sometimes it turns itself off when on, crashes or resets itself.

I looked around for what problems it may be and decided to try updating the drivers but when I turned it on, nothing. No lights, no fans, no beeps.
Replaced the PSU with another and still nothing, the LED on the motherboard does not even come on and as I know its not the PSU I'm thinking it must be the motherboard.

I've only had it up and running for a less than a week, could my motherboard be dead already? I really don't want to shell out another 70 to get a new one.

Any suggestions?


A:No power to PC, Is My Motherboard Dead?

Hopefully, you're 100% certain that the PSU that you used as a replacement really is 100% functional.
Simple possible causes of your troubles include:
Faulty wall outlet or bad power strip or UPS (Plug a lamp into whatever power source you are using--obviously, if it won't light, your computer won't turn on either.)
Defective power cord
Bad on/off switch on the case
Poor cable connection (bad wire or connector not tightly plugged-in)
Power supply switch set to wrong voltage (switch set to 115 when mains are 220)
PSU power switch not turned on
Make sure everything is seated properly--cpu, gpu,ram, etc.
Make sure nothing is short-circuiting inside the computer ( a wire, loose screw, etc.)
These are the simple problems.
I'm not a computer expert, so hopefully, someone will chime-in, after you check these basics, should there be a need.

Right i got myself a 600W EzCool power and it worked fine in my new gigabyte p31 mobo.
3 days later it turned itself off and would not work, I thought nothing of it went to bed and the next day it was working again.
However a few hours into the day it turned itself off a few more times, and eventually would not boot whatsoever.
Put my old 420W back in works fine and is quieter than what was meant to be a 'silent fan' that always ran quite loud.
Is there anyway to find out if the EzCool PSU is dead as it did not blow or anythin, it just refuses to work and the fan inside wont spin.
When i try to turn my pc on the fan on the CPU spins for about a second and dies but nothing from the PSU fan, any help would be appreciated thanks.

Sounds like a definate issue. I wouldnt recommend that brand. Your pc is as good quality as your pcu. There's not much u can do besides return it if you can.

Is your pc up against a wall maybe or in a closed cabinet?

when i turn on my pc the leds light up, the fans spin, the cdroms flicker but thats it. In a previous thread someone suggested it may be the power supply that the +5v line was broken and the +12v was okay. I bought a power supply tester and the light goes on meaning the power supply is okay.... So does this mean the power supply is working and its something else... or is the frequency just wicked low.

A:power supply dead or not?

The power supply is most likely not the problem. Have you tried unhooking the drives and booting? Are you getting any beeps at all? Does anything at all show up on the monitor when you try to boot?

Need some wisdom. My computer stopped working, and wouldn't start would just keep going around it circles. We had a power surge, and yes I have a power surge protector.
I just bought a new tower, but now the old computer won't even turn on. As in when you push the power button, nothing happen. Not even the fans inside the computer start, and no lights come on. I know nothing about power supply to these things, but I have heard that they can go. Any wisdom on this subject would be great.

Did you check the breaker switch at the rear of the case on the supply? It sounds like
that simply tripped. If not, try a substitute supply to see if that is the actual problem.

Just 20 days out of warranty, my M1530 died suddenly. It was working, then it shut off completely. I turned it back on, and it worked for about 5 mins, then shut off again. Now it does nothing at all. No lights, nothing. Power supply has been checked and is working, green light stays on. I've read numerous posts elsewhere that all say "Motherboard" but I just can't believe that to always be the case. One post I've read said "Powerboard" which I'm hoping is the case. I need to know can anyone tell me a way to be sure before I go buying parts I may not need? I have reseated the memory cards, pressed the fn and start buttons together, tried just about everything I could find in numerous forums and still nothing works. For about 2 weeks prior to this happening I noticed the battery light on the front edge would flash red 2 times, then go blue. Flash red 2 times, then go blue over and over again. But the battery showed full charge, so I ignored it. Any help would be much appreciated. Thanks y'all!

Yesterday during my computers boot process there was a power outtage, and today it will not start. I have an abit av8 mobo, ati x800 gpu, antec 560w psu, and 1gb corsair memory.
When i start the comp the Mobos onboard LCD displays error 0.4 and gives out a steady constant beep. According to this it is a memory problem, but I have swapped in memory that works for sure to no avail. The monitor is in standby mode all this time. The computer stays on indefinately in this constant beep state.

Are there any likely culprits to this problem? Possibly the PSU? I cannot swap out any other parts to check if they work so would like to figure out whats wrong first, any help appreciated

A:Power outtage = dead PC?

If there is a memory problem but it's not the RAM modules themselves, that leaves the RAM controllers. Perhaps the power outage zapped them. Remove the modules and inspect the slots closely and look for any burn marks. Likewise you might find burn marks on the RAM that was installed at the time. Maybe this isn't it, but it's worth a look. Even without burn marks it could still be bad slots. If so, you'd have to get a new motherboard.

My desktop PC was not on this morning when I got up (I leave it on overnight). Nothing happened when I pressed the power button. I then unplugged and re-plugged the power socket and it would either power up but not boot up (if that makes sense) just from plugging the power in or I could press the power button and it would come on but not load. When this happened I can then no longer switch off without pulling the power lead out of the back?

It sounds like the power unit to me but could it be the motherboard?

Hi all, When I today wanted to restart my Revo RL80 in the course of a Windows 10 update, it powered down as usual, the screen went black - and stayed so since... More precisely, when I try to power on the system, only the fan comes on, at full speed. Initially, even the power-on light would stay off. I have since opened the unit and cleared the CMOS with the respective jumper, and also disconnected the CMOS battery for a while. After that the same, but plus power light... I have also removed and reseated the RAM, and the SSD. No success. Background info: two weeks ago, I had to exchange the original 500 GB because it was getting massive failures all the time, and put in an 256 GB Samsung EVO SSD. That worked smoothly, apparently. But I could have commited the crucial mistake there - for exchanging the HD/SSD, the unit has to be completely dissassembled, including removal of the CPU fan. When I did that, I found that the heat paste between CPU and fan had gone rather dry. Since I had none handy, I still re-assembled the whole thing, and it seemed to work fine. The unit was on constantly since then, also under heavy load, without problems. But I still fear that the CPU has partially overheated and this killed the system. Any way to diagnose this further? Of course the unit is long out of warranty, but was working just fine with the new SSD. Thanks for any hints, Markus 

A:Revo RL 80 almost entirely dead, after power on on...

PS: took out the SSD, it still works when connected to another computer.

First of all, I'll point this out so its very obvious: This laptop is going back to The Tech Guys on Tuesday. The reason that I'm asking is because by the time that they are predicting I'll get my laptop back, it will have been away from me for over a month, which is more than slightly irritating for Uni work.

Now, on to the problems.

End of last year, the fan in my DV3-4050ea started bellowing away (only about 5 months old at that point), so I booked it in for a repair with The Tech Guys, as it was still under all the warranties that came with it, as well as PC support. Should have gotten it back after 2 weeks, but they needed it for another. It came back to me on Friday, but this time the Power port, the 2 usbs, and the CD drive were not working! Everything on the right side wasn't working. The power cable does work, I tested it in my old DV3 which my mum is now using.

Is there any way I can fix this, without huge work, as apparently to get to the heat sink and fan, they had to remove the keyboard, so I don't really want to do that. I am happy(ish) to take the back off, if it will be simple. I really don't want to break the warranty, as if they cant fix it and get it back to be by next Friday, I can get a replacement.

A:Power, Usbs, and cd drive dead

With all that is wrong, let the Tech Guys work on it.

My pc locked up playing GTA:San Andreas, it would not respond to control-alt-del, So I hit my keyboard button to out it into standby.

It went into standby and the little power light was blinking. I hit Power to turn it on again and nothing...

Hi, looking to get a better idea as to what this problem is. My pc won't power up. The lights on the front of the case light up for a fraction of a second and the cpu fans spins for a couple of seconds but that's all. I have tested the psu using the paperclip method and it worked, indicating that is probably not the issue. I did the same thing with the front power switch terminal where it plugs in to the m/b and this time nothing happened, which again points towards this not being the problem. Is this looking like a motherboard problem or could it be something else? I have tried other power leads and the rocker switch at the back has been in the on position. I don't have access to a spare psu unfortunately. Will gratefully receive advice on this, thanks!

I have a homemade system that just died. It has a Duron 900 that I know had been running hot (175 F). It also has a 375w power supply that also serves as a power strip. I removed the heat sink & fan to do some cleaning (spray air to knock off dust on the MOBO around the CPU). I broke one of the prongs on the socket that holds down the heat sink. A "friend" suggested using super glue to re-attach the heat sink. Now...nothing. The reset button lights up on the power supply, but the fan does not kick on and nothing else functions. Would a dead CPU cause this...power supply...MOBO...or a combination? Thanks for your consideration.

A:dead computer - CPU or power supply?

CPU sounds fried. Superglue? Really? I'd replace both the cpu and the board as you can no longer attach a heatsink to the board unless you have mounting holes and can find one that attaches with mounting holes.

I've got an Acer Aspire AX3400-E2202 AMD Athlon IIX2 215 dual-core processor.

My kids related a problem on the "kids computer", eMachine T2040 running XP. They related the computer CPU seemed to get very hot and got a funny, burning smell. Oh well, let's keep using it and see what happens. The power abruptly shut off and then they brought this to my attention.

I pulled out the power supply and found a fragged cooling fan and glue like substance oozing from one of the components. I bought a new powersupply and everything appeared to come back to life. Except the built in sound card and CD Rom now longer work. I rechecked the cord connections for data and power and they seem fine. The device manager shows yellow exclamation points next to sound card and CD rom drivers. Uninstalling them and re-installing them kills some time but has no resolution.

Question: could the high temp and sudden shutdown adversely affected and damaged the BIOS chip (where I presume the driver info is stored?)


A:Dead power supply and BIOS

The driver info is stored on the hard drive though.
You could check on the BIOS to make sure there is nothing disabling the devices, as the power supply failure could have caused problems.

You have to consider that the power supply failure could have actually damaged the devices or the motherboard though, as a prime cause.

Remove all cards, then try. If it works, add in boards until you've found culprit.

Disconnect everything from power supply except system board. If that works (power supply fan comes on) try reconnecting other devices until found.

Disconnect everything (including system board) and connect only one device, e.g. hard drive.

Oh god, this keeps happening to me. I've had so many hardware problems recently, completely ******* up a handful of days...

I'll tell you the entire story.
I have a fan on the front of the computer (quite small) that often makes alot of noise. So everytime it makes this sound, I press down on the casing or nudge it (or slap it), and it quitens down.
For the past 2-3 days though it's been EXTREMELY loud, and it's unstoppable.
A nudge shuts it up for a minute or 2, and then it starts up again. It's incredibly annoying...
So I decided to do something about it.
It's a small fan, it appears to only cool down my 2 harddrives and nothing else, so I thought I'd remove it.
Attached to the fan is a black wire and a red wire. I followed these wires back to the source. The 2 wires were seemingly forced into 2 of one the 4 pin harddrive cables (wires:red black black yellow, white plug).
[I should mention here that my computer was built by a specialist and purchased on eBay.]
I saw this and thought to my self "Easy!"
I pulled the 2 wires out and removed the fan from the casing.

When I started up the computer, everything seemed fine. No more noise!
Then I realised my 2nd harddrive wasn't showing up.
500GB of music, software and work. Important work....
I put my hand to the harddrive as the computer casing was still open. Nothing.

Hi, folks.

During a recent power outage, I was running a portable generator through a power subpanel to power fridge, freezer, and a couple light and outlet circuits. I inadvertently shut off a couple of the higher load circuits without cutting the lights and outlets first, which sent a surge through the circuits still on.

My old HP a1210n desktop and all the peripherals and accessories were connected to a power-strip type surge suppressor, but none were powered up.

The power surge fried the suppressor. After the utility power came back on (three days later) I connected the monitor, printer, scanner, and sound system directly to the wall outlet and they all work fine.

The PC won't power up. Power supply is Bestec ATX-300-12Z Rev BD. Slide-type breaker on back of PS said "reset" and I slid it back to the 115 position. Still no power.

Pulled the PC cover and there's no obvious damage/smoke around the power supply.

Is there a trick to resetting the breaker? Are there additional breakers/fuses inside the unit I need to check?

If not, I don't know how to test to see if there's damage beyond the PS. Guess that'll be a trip to the repair shop.

Any ideas/suggestions are appreciated. Thanks!

I tried to remove all power cable from the motherboard, put a jumper between pin 15 and 16 in the 24 pin connector, then the fan started and I could measure the voltage from the power supply, 3.4V, 5.0V and 11.8V.

Hello, I have a friends personal computer here, a one year old HP pavillion that quit on her one day while she was at work. She left the machine running 24/7.

When you press the power button, absolutely nothing happens.

I took the side off and though there were no lights on the motherboard, a green LED on the power supply meant to me that the power supply was at least getting power. I unplugged the PSU and then unplugged the 24 pin connector from the power supply to the motherboard. I then took a multimeter and found a ground pin and checked all the other pins for power. On a couple pins there was 5 or so volts, but there were none with 3 volts or 12 volts..., just a couple with 5 volts on them.

My questions are...

1. Did I test the power supply properly?

2. Will testing the system with a different power supply possibly put the different power supply at risk if
there is a problem now with the motherboard or some other peice of hardware in the dead system?

3. If it is completely apparent that the power supply is in fact dead, how do I determine a replacement?

A:Dead machine, press power and nothing.

Testing the PSU directly like that isn't 100% as when the power is drained off the PSU, the levels may drop because of fault. But its a good start.

Have a look on the motherboard for bulging or leaking capacitors before you try with a different PSU. see there for examples.

If you are happy to try a different PSU, ensure it matches the right output enough to power the components.

We lost power briefly at home yesterday and one of my two PCs won't restart. I mean it's truly dead. Pushing the start button does nothing. This happened about a year ago and I was able to restart it after a half day. This time - nada.... Any thoughts??

A:short power outage - PC is dead!

Shop for a P/S, it's the most likely suspect. If both of them have compatible power supplies, I'd try the other one, that way you'll be sure.

I just got off the phone with HP Support and the diagnosis is just as I expected: I have a dead motherboard. I was using my Spectre x360 and all of a sudden I hear a pop and the computer shutsoff. A hard reset doesn't work; plugging in the AC charger elicits no response (no power on, no LED). All these symptoms point to a blown capacitor, which seems to be a reoccuring issue in these forums. I bought this laptop when it was first revealed at over $1000, and now its dead, just a few months after the default warranty expired. HP, what can I do when this is considered a manufacturing defect?

Hey Everyone,

OK well here is my problem. Recently my dad moved his PC from his house to his office (onsite). This is about a 200 meters walk outside. It happend to be in the middel of an electrical storm, wasn't raining but lots of lighting. Since then, i have set his computer up again and it doesn't work at all. I have opened the case to have a look and noticed that all the fans are working, the motherboard LEDS work, as does DVD drive, but not the Burner, the graphics card fan works (which is powered through the mother board). The USB inputs are producing no power and the graphic card isn't producing any connection to the monitor. What seems to happen is the copmuter turns on but nothing works. Is it fried? What do you think has happended and why?

Thanks, any interest would be appreciated. I have also taken both hard drives out and installed into second PC to check is they are working. Both the hard drives are not recognized.

I am lost of what to do?

Regard Liam

A:POWER works, FANS work, PC DEAD?????

You get NOTHING but moving fans? No beeps or anything, no input to monitor?

First thing I'd do is re-seat your ram modules. Just take them out and plug them in again. They may have come a little loose on the move. Happened to me once and scared the :hotouch: out of me.

If that doesn't do it, take out your vid card (if you have one) and re-seat it. Do it to all your add-in cards.

Let us know if this works, and welcome to Techspot!

I suspected some hard drive issues on my friend's computer and ran chkdsk. There was a power failure while the utility seemed stuck at 27% for all eternity, and now the computer won't produce any image on the monitor (which I have tested on other devices) or sound on the speakers (also tested) when it boots.

Remove all expansion cards. Disconnect all drives. Basically only have the minimum things connected that are needed for the motherboard to POST: usually motherboard, RAM, and CPU. If the computer won't POST at all when the minimum hardware is connected then try connecting a different power supply. Alternatively, the computer might start POSTing again. If the motherboard doesn't have integrated graphics and it does have a little speaker plugged in to it someplace on the board (usually near the headers for the front panel) then you should hear some POST error beeps that indicate no graphics system was found. If you hear the error beeps then at least you know the motherboard performed a POST which would be better than what you're seeing now. After POST starts working, shutdown the computer, and start reconnecting drives and cards. Try one or two things at first, power on the computer and watch if it POSTS ok again. If the POST doesn't happen then you'll know one of the things you reconnected may be the problem. Notice I stated may be the problem. The piece of hardware might actually be ok but the power supply isn't functioning like it did before the power outage and might have trouble only after adding a certain part. If you figure out what card or drive is causing the computer to not POST I recommend trying the card/drive in a different computer to see if it still c... Read more

Well, A few weeks ago I posted this thread:

I was having problems with BSOD's, and after running MEMTEST 86, I kept getting errors in the RAM, so I was set on replacing the RAM that I had. Tragedy struck first, however. For some reason, flicking the switch (in the uk they have switches to turn the actual socket on/off)a few days after I had decided to get some new RAM sticks, it must have 'detected' it as 110 volts (rather than what it should be, 220+ volts). The power supply, for a lack of a better description, 'blew up'. I was obviously extremely pissed off. Not only would I have to replace the RAM, I would also have to get a new power supply. Everything was plugged in and installed when it blew up. The machine was off when I flicked the socket switch to ON, and it blew up, a bit of smoke billowed out of the power supply, I knew it was dead.

So I ordered a slightly better power supply, a Corsair TX 650W (I had an NZXT 600W before), which also automatically detects voltage. I also ordered 2 2gb sticks of corsair ddr2 800 mhz ram.

let me reiterate that the computer was actually OFF when the power supply blew up / got fried / etc. not sure if it makes any difference, but it may be worth pointing out again.

so i put it all back together again slowly. the power supply goes in, the motherboard was already installed with the processor on it, the heatsink goes in... Read more

When a power supply blows you have to check each component individually. I've seen blown power supply's only take out the board and everything else was fine, and i've seen power supply's blow and take out everything.

If you don't have diagnostic equipment/parts to change out take it to a shop.

I have all my data, and a new pc is already ordered. But I'm wondering what my options are on this old machine, and wanted to get some opinions. (Mods....if this is the wrong place for this question, please move to proper board.)

First, this is (was) a Dell Dimension 8400, from 12/2004. Config with 160GB hard drive, CD burner and DVD reader, floppy, 1GB ram...a decent machine. The pc was on (connected to a surge protector, but not a UPS) and the power went out for about 10 seconds. Power came back on, and I didn't even check the pc until hours later. Well it was an ugly UGLY blue screen, couldn't even boot in safe mode, or to last state. I had a guy check it out, and it was all he could do to get the few files I needed off of it, he said he had never seen one get hit this hard from just a surge. Anyway....I really didn't press him for much info, but I have the thing sitting in the floor now, and I'm looking at it, and thinking....what should I do with it??

If I donate the thing, I really need to have the contents of the hard drive removed...although, I really don't know how to even access it. But, would it be possible to just purchase a new hard drive, install it, and create a new system?? I mean, the case is fine, it sure seems like a cool project (I have been inside a pc and replaced boards before, but it's been a while! ) Does this sound like a worthwhile thing to do? Does everyone just toss their old machines without giving a thought... Read more

While playing Mount & Blade, my computer turned off and would not restart. It was clearly dead, as pressing the power button did nothing. I drove my computer to a technician, who installed a new power supply.

I drove home and immediately began playing Mount & Blade. After a few minutes in battle my computer turned itself off. It was dead again. Repeat visit to technician to replace power box.

He said "if happen again, then motherboard like to eat power box." I presume that he is very smart, but a lack of good English keeps his words few. Still, I was not looking for a philosophical explanation.

I wonder what the people here think of this. My temporary solution is to delete Mount & Blade from my system. I have tested Oblivion, but only for a few minutes. Before I begin to use my computer to play games again, what should I do?

Help! I built an Athlon machine from used parts, an Abit KT7A mb, Athlon Tbird processor,3D Prophet 4000XT AGP Video. New CD/RW and HD. Installed XP Pro, updated to SP2. Ran great for 2-3 months.

Now it's dead. I donno if I had shut if off or left it running for a week or two, but hadn't touched it. I found it off. This is what it's like. I press the power button, the green power light flashes once. The light on the CD/rw flashes. Then everything is dead. If I unplug it and plug it in again I can repeat this.

I have disconnected all cards, CD, HD, floppy, and unplugged both Dimms. Same thing. Googling around, it seems like the brief flash of power is supposed to indicate a short. You're supposed to disconnect all peripherals to isolate. That hasn't helped.

Oh, on ps connector to mb when I unplug it and test with a multi-meter I get 5.0 volts across several of the wires or when grounding them to chassis (through multimeter voltage test). Is this correct?

What should I try next? remove mb, put on antistatic mat, hook up power supply, and jump start pins?

The power supply died on my desktop pc (asus board with amd proc and windows xp home edition with sp3). Replaced power supply and eventually determined that even in safe mode it would
boot as far as mup.sys then reboot.
Running chkdsk from installation cd fixed it somewhat.

It boots ok now and makes it to the desktop with mouse and keyboard working but:
- no start menu or taskbar
- wallpaper and desktop icons are present
- during bootup several messages are displayed saying I don't have permission to change settings in catalyst control center (software for ati onboard video)
- can access/edit/view desktop documents created with apps such as windows notepad, openoffice and google sketchup
- can view saved .pdf files
- can access and view desktop folders
- cannot access files (mp3, mpeg) that use windows media player - nothing happens
- cannot access desktop shortcuts to websites or a saved webpage on desktop (.htm or .mht).
This results in error message "there was a problem sending the command to the program".

I'm stuck.

My brother's computer - which is a custom made system - recently starting having weird issues. The screen and all USB devices would shut off, but the computer still had power. Pulling the CMOS battery would let it work again for a bit of time, but we eventually determined that the motherboard was going bad in some way and replaced it with a brand new, identical motherboard.

That solved that problem.

Not a week later, his power supply gave out. He called me and said he smelled burning and then the system just shut down. I figured it was just a coincidence that both parts went dead in the same week - after all, the thing was running perfectly fine with the new board. So we went to a local store and picked up another power supply; it was a slightly better one, which was probably not necessary as the older PSU had been running in his computer for well over 6 months with no indications that it was underpowered.

You can guess what happened next. Hooked it up and everything was fine. Computer runs for three days, and boom, the brand new power supply is now dead (I assume) as well. He called me tonight and told me he just lost power and it won't turn back on - though no burning/smoke or anything like that to his knowledge.

No idea what is causing this right now. I don't even have any wild guesses left. I need some help.

Hi techies,

Is this a battery problem or is it as I feared, the power section on the board is fried? Do I have to get a new laptop or can that part of the board be replaced?

For the last two weeks, every time I start my Dell INSPIRON E1705 while using the power supply I am greeted with the following message. "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation". I press the F1 Key and everything works fine. I've read about this on other websites and most say it's a design flaw in the power supply after the cord has been properly wound around the supply as designed. Apparently a few of the cords internal wire strands become broken and cause this message. My computer is from June 2006 and shouldn't be having this issue so early...or ever. This seems like a flaw that should have created some type of manufacturers recall since so many people are having this issue. I'm of course out of warranty, will Dell replace this free of charge?

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

My dad said he came home the other day and smelled something "electrical" burning and traced it to the computer, so he unplugged it.

I plugged it in to test it, and got a loud horrible sounding beep (so loud i'm not sure if it came from speakers or the hardware??) and then nothing happens Won't boot up. I just hear a vibrating/sickly humming sound in the box that is in the back of the case, with a fan, and as far as I can tell the fan is still spinning, so the noise most likely isn't the fan. Would this 'box' be the power supply? I am guessing so since this is where the power plug goes in at. Also, if it is indeed the power supply, would this problem inflict damage on other components?

I got a Gateway MX8711 laptop, it was supposed to be just missing an HDD, but the unit is completely dead. I've never got to see any indicator light, any whiff of a fan.

Since the alternative was throwing it away, I took the whole thing apart. All I know is that the PSU tests successfully at 19V, no obvious indications of burns or bad solders near the POS, and there is continuity on the board. The highlighted transistor S1040 gets 19V too*. The battery charge terminals give 0.85V.

A:Gateway laptop completely dead, mobo gets power

Sorry to report this to you, but the Gateway Ml, M7, and MX series of laptops from about 2007 through 2010 or later, have a very high (my term) failure rate... the motherboard goes.... Some technicians believe that the motherboard fails because the CPU cooling fan plugs up with lint, and the board or processor overheats... We have seen perhaps 36 or 37 of them... dead and not repairable... since 2007... except by the replacement of the system board... The average cost of the system board is $127 plus shipping...
Others believe the failure is because of the manufacturer who was in control at the time they were built... The problems appears to be the same whether it was built by Gateway or the other two companies who have been in line for the building process. Gateway was bought out by other companies in Korea about 2003 or 2004... a pretty reliable machine until then
I would contact Gateway or a technician who specializes in Gateway to see what their cost of repair is these days... but we are not sure we would want the repaired one either...
A look on eBay will affirm that there are lots of Gateway parts, but almost never any working Gateway motherboards...
You might want to take it to a certified tech who works on Gateway laptops for his or her evaluation...
But your time will be better spent shopping for a better unit.
