Ethernet to USB adapter (with power supply)

Q: Ethernet to USB adapter (with power supply)

My internet setup is as follows:

Internet > wireless > 4G router > wireless > Main Router > PC (wired) and other devices (wireless)

As you can see the Main Router (which I connect all of my devices to, because it's faster in terms of internal network speeds and has a longer WI-FI range) connects to the 4G router (which is the access point to the Internet) wirelessly.

I want both routers to be wired. However, the 4G router has only a single Micro USB port which also acts as a power supply and the Main Router has no USB ports.

So what sort of (Micro) USB to Ethernet adapter should I buy (suggestions from experience welcome)?

Is it possible to transfer power from the Main Router through its Ethernet port?

If I use an adapter with a separate power supply, will it supply the 4G router through the Micro USB port?

Main Router: Tenda W308R
4G Router: Is an Infomark Biscuit Mini provided and customized by my ISP.

I have a 20 pin motherboard but the power supply I have available has a 24 pin connector. I've read that you can simply plug them together by offsetting the 24 pin one but so far I don't see that working at all (and 'never the twain shall meet', so to speak). I've found adapters but they all say something akin to

'allows you to connect your existing 20 pin power supply to your new 24-pin compatible motherboard'

You can use it the other way around, correct?



A:20 to 24 pin power supply adapter

Some mainboard connectors are 20+4 pins where the 4 pins unsnap from the 20 pins for use with boards with a 20 pin connector. If your power supply doesn't have that feature you would use an adapter such as this.

I want to buy a replacement for my outdoor AP. my AP has injector that has output of 48V and 0.4A.

what is a suitable one?

I know that when you buy an DC adapter, you choose one with the same voltage but for the current you can buy one with the same or higher.(the device is the one pulling the current so you don't want a weaker adapter with lower max current)

I don't know if it is the same for the Ethernet injector

A:choosing Ethernet Power Supply Injector (POE) for AP

Well, 400ma seems pretty standard, but if you find one with more capacity, I can't imagine why it wouldn't work, it's plain DC power.

Am looking for an adapter that will fit a Sony pcv v1/g computer 18 pin motherboard PS connection to a 20 pin normal PS.

It seems difficult to find a replacement PS - Sony only supply registered repairers (any ideas?)

So I hope to use a normal PS, that could have an adapter from 20 pins down to 18 pins - would this work - or would I blow it up ?

I have recently rescued a 15 inch viewsonic lcd monitor from being trashed at my work. I did not find the ac adapter for it and would like to use one of my old PSU's to run it. Since the power requirements for the monitor are 12.0V 3Amp, I assume I can just use the 12.0V rail on a standard PSU and attach a tip to it (which I have from a broken universal wall-wort). Will this work? Can't I use any power supply/ac adapter that is capable of supplying 3Amps or more of current as long as it is 12.0V? Thanks in advance.

BTW...I did try a duracell battery charger ac adapter that ran at 12.0V and 2.5A for a short period (as to not damage the ac adapter) and found that the monitor works fine (just has a little fraying on the VGA cable). So I know it is worth converting a supply for it.

A:Use a Comp Power Supply as an ac adapter?

A 12-volt supply capable of 3 amps or more is all you need. Just be sure the polarity is right.

I have a 12-port network switch in my shop that's been running off a 5-volt leg of an old computer power supply for several years. At the time, the manufacturer wanted as much for the power supply as I paid for the entire switch and power supply the year before. Old computer power supplies are plentiful around here.

The situation: Dell Inspiron 600M. Laptop won't turn on, when I press the power button, no response (at all). I think it's either the power supply or the adapter. The only reason I think it is the adapter is because the green LED doesn't come on, but the user said it hadn't been coming on for some time before the laptop stopped working altogether. The user has already gotten a new computer and really only cares about the data. I'm trying to decide the best direction to go: Adapter or SATA/ATA to USB converter? I'm pretty set on the converter, but want to make sure I won't have to reformat the HD for it to work with the adapter. I think the laptop has a PATA HD connection. Will it work on most of the converters?
Another side note: I have had no success yet finding another adapter that worked. I did try an adapter for an Inspiron e1705 (90W) and when I plugged it in it reset the adapter. I thought the adapter for the 600M was also 90, but I guess not.

I bought my TravelMate 4260 in 2007, so almost 9 years old, but still working fine, except I have changed a screen and power supply adapter. Yesterday, the adapter went out of order again. I am not sure what happened but I assume it was simply too old and run out of its life. So I started to searching for Acer adapters ( I haven't looked at adapters from other Laptop manufacturers as I am not sure if it will work on Acer laptops ). I found this adapter that has the same plug and voltage etc. It says output is 19v 4.74a, which is the same as my old one. So hope to get a final confirmation if laptop power supply adapters could all match together if the plug and output are the same. Cheers ~ TJ4000

I am writing this from my desktop. I just got a new HP Laptop (Pavilion) which came with a 45W power adapter. The power cord section (which plugs into the adapter) is shorter than the one on my older HP Laptop (G60-63OUS Notebook). I would like to have a longer power cord section or, in the alternative, could I/should I use an extension cord to reach the wall outlet I want to use. The older laptop has a 65w power adapter. I have 2 questions:

#1 - Can the power cord section from the 65w adapter be used in place of the one that came with the new laptop? I would, in effect, be mixing the two because the 65w adapter plug is too big for the hole on the laptop.

#2 - Can I get a higher power adapter for the new laptop or should I leave it alone?
Another question I have is regarding the use of cordless earphones to watch TV while working on the laptop. When the laptop is plugged in (to recharge the battery), I get static noise in my left ear. When on battery only, there is no noise. Is there a solution to this?

A:Laptop AC Power Supply Cord and Adapter

#1 Yes, if the older adapter's power cord fits into the new adapter you can use it.

#2 There's no need to get a more powerful adapter, the new laptop must not need as much power as the old one.

Now what? Would you experts trust this drive with a new power supply? Or should I crack it open and put the actual drive into a new enclosure? i feel like a hard drive I can't trust is useless to me. Am I too paranoid? Your opinions here will be greatly appreciated.

I want to buy a Power over Ethernet adapter for my computer. I need to know if this will let me plug a cat5 cable in the adapter and then the other end in my computer and have internet. And I just have a question. Does this take a lot of power? How much on average a month would it cost to use PoE? And can anyone suggest me an adapter that will let me do this with good speeds (if it will let me connect to the internet)? Thanks!

A:Will a Power over Ethernet (PoE) adapter give my computer internet?

Are you expecting to run your computer power wise from this PoE adapter? If so, you need to lower your expectations as all commonly available adapters don't have enough power to do this. The most common spec and one you'll find most PoE devices you purchase through normal channels can only supply up to a max of 15.4W meeting IEEE 802.3af standards.

The other part of the equation is that the device you purchase has to be able to support PoE. So I highly doubt the onboard NIC (or any add in PC NIC adapter) supports PoE.

The adapter you are looking to use is probably an inline power injector to help feed a PoE capable device like a VoIP phone, WAP, security camera, etc. The adapter is used in environments where there is not a capable PoE switch being used.

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.

I have an ethernet cable run in my house. What I need to figure out is if there is such thing an ethernet switch that does not require a power source. (or something that can get this situation resolved)

Here is my situation:
I have a cable ran to my basement, and have a bedroom directly above the basement that needs an ethernet run. It is not possible for me to run a completely new cable from the original starting point, so I was somehow hoping to use the cable going to the basement, put a head on it, put it into a switch/hub/splitter and run a cable out of it to the room directly above, and use the other cable coming out to stay in the basement.

Is there something that can do this for me? Is there a better way to do so? What would you suggest? Thanks!

If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

I just want to have the fracking thing working with the right PSU.

A:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

I'm interested in the Toshiba G25 laptop but have heard that you can't use it on airplane seat power. It comes with a 120W AC power supply (15Vx8A), but I've been told that most airlines limit seat power to 75-90W max. Lind sells a 12V car adaptor for the G25, but specifically won't include an airline plug for this reason (which I can get independently, of course). I've read some interesting electrical discussions on this board. Can ya'll comment on the following or provide any general advice about power consumption?

1) Given that the voltage of the laptop and airline seat power pretty much match up (12-15V), if the amp draw on the laptop exceeds what the airline power supply can deliver, what will happen? Will it damage the laptop to feed it insufficient current? Will it shut down the laptop altogether? Merely dim the screen?

2) If I remove the laptop battery, which requires power to charge it, how much will that reduce the power need of the laptop? I'm not sure how to work the math, but the spec sheet states the battery supplies 4400mAh at 8A output. Does it require the same to charge it?

3) Most importantly, on my 15 hour transpacific flights, will the DVD player work with that ultrabrite screen at the low airline power supply?

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

I have terrible luck with random bsod's and power supplies pooping on me, I want to pick one this time that will last me. Also, I have my power running through a Monster Power HT700, I live in a new apartment so the wiring should be ok, I've dusted out all of the components inside the case, double checked my connections, all that jazz. I've got a cooler over my memory, I am still using my stock cpu cooler, but thats changing soon (I get crashes @ idle too) Any help I could recieve I would appreciate, thanks

You have pretty much the same problem as me (getting BSOD's randomly). For me it's bulging capacitors on motherboard. You should take a closer look for capacitors on your motherboard. Dead capacitors look something like that:

I shut down my Pavilion Elite for 1 week while away and now it will not turn on. The power supply light is on, I replaced the CMOS battery and the power switch is ok.

A:Pavilion elite power supply light on, won't power up

As you did not mention any message or display on the screen, I would use this tutorial for a step by step diagnostic.  It also helps to remove the side panel, and visually watch the CPU and rear case fan movement(s).  As you press the power button, pay attention to the fans. Also does the Power Supply LED stay ON? Or did it go OUT when you pressed the power button?

My first post...

I received my new DVD DL +/-RW drive today and eagerly installed it. I of course unplugged my computer's power supply while doing it. After plugging the power back in, the green LED on the back of the CPU started blinking (never noticed this before), and when I hit the power button, NOTHING happen. No fan turns, no lights, nothing. When I unplug the power supply, the green LED blinking gets slower and slower, and after about 15 minutes it totally stops. I plug the power suppply back in and it starts blinking all over again and still the power won't turn on.

All I did was replace a CD-ROM drive with a DVD Multi drive. I didn't mess with anything else, so there should be no power supply shortage or problem. Any thoughts as to what could be happening?

By the way, I have a 2 year old Compaq computer with 2.0 ghz Athlon 64, 1 gig RAM, no problems thus far.

While installing the new optical drive, you might have inadvertently loosened one or more connectors. Recheck all data and power cables to make sure they are tight, including all those to the motherboard.

Hi !! All,

Happy New Year to all members and technical assistants.

I have a little issue in which I require some help and guidance.
I have a PIII 900MHZ 256 MB memory with a ASUS MB-

Recently it died on me and assumed that the reason I could not get to power
it up is due to my power supply. I went out and spent the money and bought a brand new power supply from a computer retailor. I saw him remove it from a brand new case.
I installed the power supply , trying to power it up, I can see the fan rotate a little bit but not enough to power on. Changed socket and it power on.
It booted up but after 30 sec, it shut itself off and now I cannot power it back on until 15 min. later when I went and change power socket once more.
This time, the power did not stay up very long. As soon it powered up, no more than 1 min later while it was loading windows Xp, it shut itself off nad now again can't power it back on. I have a power extention and power bar in which I used and both shuts the computer off. Anything else plugged to it doesn't seem to do any affect. This is the second new power supply I'm trying.
What else can it be ? I have not tried to place the computer in a different room on a different plug yet. I will try that tonight but in the meantime, what else can I try ?

Thanks for your help and listening.

Cheers !!

Hello, everyone - I have just assembled a new build. It will not power up. I need a suggestion to figure out if the problem is the case or the motherboard.

This is a mini-itx build. The case is Linkworld LC820-01B. This case comes with a 12 volt 65 watt external, laptop-style power supply that plugs into the rear of the case just like a laptop power supply plugs into a laptop - a barrel connector. Inside, this power connection connects to a power supply component that is not like a regular ATX power supply, but is on a printed-circuit board mounted on the case. This has several capacitors and other stuff. From that comes the 20-pin and 4-pin power supply lines for the motherboard.

I assume the 12-volt power supply for this external power supply unit is right, since it came with the case. It was 65 watt.

The processor is an IBM 1155 3220t, with TDP of 35 watts. Lower-powered CPUs can be put in a small 1155, so I assumed the power supply might be under-powered. I ordered a 90-watt 12 volt power supply with the right size barrel - and same polarity (pos inside).

The MB is an ASRock H61MV-ITX. It is 1155, mini-itx form factor.

Still, same problem.

Everything is connected correctly.

When I press the power-on button, an external CD drive I have plugged-in spins up for a while. But no power light comes on in the front of the case, there are no POST beeps, the fan for the CPU does not spin up. No other signs of life.

So, power is getting into the MB - the external CD drive i... Read more

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

Hey, got quite a problem with my laptop.. It's a Medion Erazer X7813, worked well for ~2 years.
I was doing a graphics card benchmark yesterday and it stopped in the middle of it(monitored temperature, it was at ~80 degrees Celsius when it turned off). No bluescreen or anything just off and I couldnt restart after that(no fans nothing). I thought it might be the power supply, so I tested it, but it was doing 19v when not plugged in, but when I plugged it in and unplugged it again it was at 1v. When testing I unintentionally shorted the power supply and it showed 1v after that just as it did after plugging it in, is it shorting inside the laptop? Could it be the battery or something more serious like the MB? Any ideas are welcome!

I'm currently a computing student so I rely on my computer a lot for my studies and was hoping I could get some quick advice/troubleshooting on here. So here goes :

I've had a problem with my computer recently, it's been working fine for a year or so with no problems, and then one day i tried switching it on and nothing happened. I tried once more and then the power short circuited (I then had to turn the power back on from the mains switch).

The strange thing is, my housemate had exactly the same problem, and after searching for the answer , he was told it was due to a static buildup and the solution was to take out components (graphics card, RAM) e.t.c and put them back in.

I tried this and no luck , I was thinking due to the short circuit, there may be a problem with a fuse in the power supply? other then that I'm completely stumped and would appreciate any help given.

Many Thanks for all help received

Hi everybody,

I tried to search on google about this, but it's not really help and it never happen to me before so I post here.

My PC was running normally for a long time, just couple weeks ago I sent my faulty video card (xfx nvidia 8800 ultra) to get warranty service and they sent me back another. The new one works fine, but a week later I tried to turn on my computer and there's no power at all. No lights on, no fan running, just no sign of power. So I check inside if there's any wire from the PSU is unplugged, but everything looks good, nothing seems wrong. I'm sure the power from the wall is good and the power switch on the back is on. So I tried to check the wired again, push the power cable to the mother harder and press the button, it worked. But that doesnt solve the problem, if I put something heavy near the PC or the desk is vibrating a little bit, the power turns off. I press the power button again it would not turn on until I open the case and press the power cable to the motherboard harder, it's on. I then close the side panel, it's off, no power.
This is really annoyed me, I dont know what else to do. What caused this problem? The power supply or the power button? Can somebody help me?

My system specs:
ECS G31T-M mobo, Intel E8400 Duo, 2x2GB RAM

Finally broke down and started building a new system -
I'm too old to game, this all started out as a home video

Anyway - gathered all my components, now I'm working
to assemble them.

The case came with an Okia Model 500-ATX power supply.
But no wiring schematic.

I'm trying to identify the power supply fan plug - what seems
to be it doesn't at all match the connector on the board.
And I've got that positively identified by the board manual.

The board has a small male 3 pin connection. The only thing I
can find that might be the fan connector coming from the
supply is a small 4 pin plug at the end of 1 of the strings of
drive power harnesses. Nothing tucked up behind the
supply case or anything.

Is that likely to be it? Or would that be for a floppy or something?

I tried to Google for a wiring schematic, but could find nothing.
In fact, nothing much at all on this brand of supply - just
a couple places that sell them. Please don't tell me I got
an el cheapo that isn't worth having!

At the risk of getting ahead of myself, in case I need to adapt
something like that to the different style male connector on the
board, in this case or something else I may find as i progress,
is there some type of source for adapters, or what would I do?

A:New power supply, no schematic, looking for power fan plug.

There are basically two voltages available to you: 5V and 12V. Doesn't really matter where you get it from - some pin on the mobo or some wire from the PSU.

From the PSU the yellow wires are 12V and red ones 5V, black is ground. The fan voltages should be written on the fan itself, the black fan wire is ground, red may be 12V or 5V depending on the fan voltage.

Fan headers on the motherboard should be labelled so, check with a voltmeter what pin gives out what.

I have a server that I would like to upgrade to 20 1TB Hitachi HD's. They claim max startup current of 2A. and idling down in the .5A range. The platform will be a 775-series X48 with a 6600 Core Duo. Graphics card is small, does not even require aux power connector. Not needed to just supply the KVM with 1280x1024. No other signficiant sources of 12V drain exist other than the MB/CPU, a slim CD-Drive for installs, a slim floppy, and one additional 30GB SSD startup drive (2W when active).

I am looking at an 850W Corsair. I've heard these are quality supplies and I don't want multiple rails since no one really knows what sort of Voodoo goes on as to how they divide multiple rails up. And I don't want to get into that. I will be using a single-rail +12V PS. I can add a second if I need to but I'd rather not.

Do you think this will be sufficient for handling 20 Hitachi hard drives? "Green" drives are a non-starter since they will drive my Raid 6 controller, and then me, off the deep end with TLER issues. I do have staggered spin-up control of the drives with the controller.

Thanks for any help.

A:Power Supply Question & HD Power Consumption

Power Supply Question & HD Power Consumption, Pt. 2 - Laptop vs. 3.5"

My second question is this - I have a BTV server that needs to be on at all times during the season to record shows during day and evening.

Suffice it to say that you CANNOT reliably put one of the critters into sleep/hibernate mode and expect it to wake up and reliably record a show. It just won't happen.

Now, this is one case where I can use "Green" 3.5" drives, but I am also considering banking 500GB 7200RPM or even 5400RPM laptop drives. These will all be on a raid controller, but since they will be in pass-thru mode or RAID 0 mode the controller won't freak over TLER like it would with RAID 5/6 and mark the drives bad. The controller also has more than adequate cache to handle a 5400RPM spindle as OTA HDTV generates little more than 2.5MB per second per channel. Even 4 channels at once is 10MB/s and that should not tap the ability of a 3Ware controller with cache on 5400 RPM RAID 0 or even pass-thru drives.

My question is this - 2 500GB laptop drives burn much less startup and idle current than a single 1TB 3.5" drive. Has anyone tried running multiple laptop drives on a RAID controller, and what sort of luck have you had? What sort of sustained throuput can you obtain?

Electricity is a huge factor here, at 12 cents per KWh. I can recover the marginal cost of 2 500GB laptop drives vs. 1 1TB 3.5 drive.

I have a generic MB (P-120 CPU ) which I just switched to a different case and power supply. It has an extra "six pin power type connection" in the middle of the board. Only one supply that I have matchs this and the wires are three green and three black. What is the funtion of this connector, it looks from the wire colors to be some form of switch.

Its a case of not wanting to swap out the power suppy from my other unit unless necessary. I have 4 other supplies and none have the extra wire, which is listed as P10.

I'm assuming that in "winipcfg" the dropdown is not showing your NIC as an option.

right-click on Network Neighborhood-select properties
on the installed components list make sure that you have the following...

Client for Microsoft Winfows
Realtek ethernet adapter

If you have any VPN adapters, remove them. also removew any AOL adapters and all protocols other than TCP/IP

reboot and check it out. If the NIC now shows in WinIpCFG, do a "Release ALL", then close out and power system completely off. Then cycle the power on the DSL Modem, wait for it to come completely back up, then reboot the PC

I pressed the power button on the front and got nothing. i checked the power supply's own power on/off switch on the back and got nothing. no light that its on or anything. thought maybe it was the cable so i plugged it into my other pc and the cable works, so i'm thinking maybe the psu went bad or took a hit. Im guessing i just need to replace it. How difficult is it to replace it by yourself. i've never done that before and do you think that its the psu at fault? I'm thinking that if there is not power on light, then something is wrong big with it. my heat temps stay down between 28C and 34C at the highest. Also, can i replace it with just any other 600w power supply or does it need to be a specific kind. company i bought it from online listed it as dual core certified 600w psu. no mention of 12v rail or anything else. i guess i can get that from them if they have it on file.

A:No power to Power Supply, no lights

Well sounds like your power supply took a power surge. Well to start with i would try a power supply. Now about replacing the power supply cheap is not the best way to go, learned from experience. Here is my recommendation:
And for replacing a PSU not hard. If you need help removing it Post back i will walk you through step by step if need be.

My PC suddenly shut off and wouldn't turn on, but the mouse and motherboard lights were still on. A tech took my PC and ran some tests. I assumed that either my Power supply or my Motherboard was unfunctional but he called me back telling me that it was neither, and that the problem was coming from "a part" that gave power to the motherboard. The replacement of this part would cost $80.

Am I getting ripped off? What part could possibly cost $80 and isn't the Power supply?

Ok so, i do know what the problem is, this is more about what i can do to use my computer until i can fix the problem. Ill start off with what the problem is. My computer wont turn on, from the get go i knew the power supply was okay because the mother board has a green light on it showing that its getting power. of course, just in case. i tried putting a new supply in but there were no changes. At first glance the mother board looked good. No blown resistors or anything of that sort, i sent it to a friend to check it out though, once again just to be thorough and sure. Finally after hours of tedious searching, i found the problem. The chip that the power button plugs into has blown out! Very happy thats all it is. Now, my question to all of you, is, is there anyway to bypass using that board so i can run my computer until i replace it? if i just unplug the little board that the button is a part of, the computer obviously does not turn on when i attach the computer to power and i dont know how i can trick it into turning on without having the use of the power button. Any info would be greatly appreciated.


A:Power supply and mobo are 100%, no power

There are some motherboards that have a power on button directly on the motherboard. I don't suppose you have one of those? There are some BIOS' that can enable the keyboard to power on the PC by pressing any key. I'm using one of them now. Of course, the problem with that is to get the PC started in the first place so you can change the BIOS setting (if it has that setting).

What motherboard do you have?

Hi QGamez,

I reckon a 500W wouldn't be enough but a 750W may be the right one. I had a look in a few forums and they had 650W & 750W etc but not 500W.

hey.. I have an interesting problem.
When I plug the atx power supply into my motherboard as soon as it makes contact the psu fan spins about 4 times then stops. which i suspect means its testing to see if it works or something. But i have a computer out of the case and i might have made the fatal mistake of useing a paper clip to "jump start" the motherboard by contacting the power jumpers. now whenever and metal contact is made (paper clip, the actual start mechanism, anything) it won't cut on. Well me, thinking i must have messed up the jumpers, cut the psu green and red cord (i double checked to make sure they were the power on cords) and twisted them togeather and put electrical tape around them. I know its not the best job but i was just testing a theory. When I plug in the psu and its plugged into the motherboard the psu fan becomes turned on (because of the twisted on wires) and spins. But the cpu fan and motherboard remain powerless. I am wondering if i've done something wrong or have screwed something up... any help would be appreciated.
ps. before the problems begain i installed the motherboard into a case because it was just components and i founnd a cheap case. When I installed the motherboard I screwed metal screws into the contace points where the motherboard is supposed to rest. I heard somewhere metal is bad for the bottoms of motherboards so that could be it. thanks

Went to dinner, left PC running. Came back, PC shut down. Would not power, lights, fans, LEDs...nada, zip, zilch. We had a brown out a few days back...I figured the power supply finally crapped out. Tonight installed a new power supply (Antec Smartpower 2.0 350w). No change! I push start button....absolutely nothing.

I have checked:
a) power at outlet OK
b) changed power cords, original is cord OK, but I notice when I insert the plug into the recepticle there is a spark. Now I'm not much of an electrician but I don't think there should be a spark for just plugging it in.
c) I have plugged my backup PC (this one) into the same outlet on the surge protector and it's running fine, soooo... the problem is in the computer.

If I plug the power supply in...shouldn't the PS fan run? It doesn't.
Can there be something bad on the (shudder) mobo, like maybe the start switch or something?

Also confusing me...I have sata HD, this new PS has power plugs for sata. My old power supply only had the regular 4 pin plug that I plugged into the sata HD yet it ran fine. Do I need to use the sata plugs on the new PS?

I have a Windows XP Home Edition SP2 computer.
768MB Ram

Last week I installed SP2 on my computer because I had SP1 and decided to upgrade.

A couple days later when I click on "turn off" my computer restarts NOT shutdown... When I click on "stand by" The screen goes black, then I get a "blue screen" (Like in Windows 98) But it's dark blue and stays up for only a second. Then the computer resets.... The next day my computer stopped that but then As soon as I press the power button the TV in the living room goes all fuzzy.. I turn it off. I remove the power strip thinking that it went bad... I do use every plug, but other power strips in the house are full too....I plug it directly into the wall. The restart stops, still fuzzy. I unplug ALL the connections in the back of my PC except the Power and monitor...... It stops.. Plug it all back in. Put it in another outlet in my room. Does it again.... Change HDD power cable.. (motor could be causing this?) I finally realize that it's the TV tuner card. The cable connection is already being split into 1/7ths! I had a bad plug on the TV splitter so the fuzziness got fixed.. I put the power strip back on and the restart is going on again... I tried on a outlet too....
Why is my computer restarting when I click "Turn Off"? Is the "shutdown.exe" corrupted?

I just formatted my drive and reinstalled Win98SE. I have a 10/100 PCI Ethernet Adapter. The Device Manager is not listing it. I'm pretty sure the driver is missing. I went to the manufacturer's website and downloaded what they listed as the driver for it. When I unzipped it, I got, netrts5.inf and Rt8139.sys. Shouldn't there be a .drv file there somewhere? More importantly, where the heck do I put these files? I don't have a clue.

Thanks for any help you can give.

A:Ethernet Adapter not recognized

If the PC isn't recognizing it at boot up then there might be a problem. Is it showing up in device manager? When installing the drivers you downloaded it will look for the .inf file as a reference to where the fles are and where they will be installed and any registry settings. Put them on a diskette or a folder on your hard drive.

Trendnet doesnt seem to have win 7 (64 bit) drivers. You might be able to use their vista driver if you install them in compatibility mode.

This is really weird... I have been trying to install an Olicom OC-2232 PCMCIA modem/ethernet combo card on my old Win98SE laptop. I downloaded the latest drivers from the net. I installed the card, and the modem part works fine, and the Device Manager says the Ethernet adapter is also working properly (no exclamation mark over it either).

In Control Panel / Network, I see the Ethernet adapter and a TCP/IP protocol entry for it. The bindings and all the settings are as they should be.

But ipconfig and winipcfg don't see the Ethernet adapter at all. The only adapter I see on the menu in winipcfg is the PPP adapter. There are no "standard modem" devices in Device Manager, only the Olicom PCMCIA modem device which works and dials ok, so I do have the Olicom modem/ether combo drivers installed properly.

I have tried uninstalling the whole Communications part of Windows 98SE and then re-installing the networking stuff from scratch. That didn't help either - the Ethernet adapter is not seen at all by ipconfig or winipcfg.

I'd never heard of Ethernet to USB adapters, but they're out there. I can't seem to figure out exactly what they can be used for, though. It appears you can use one (EDIT) to connect to a wired network (/EDIT) if your laptop doesn't have an Ethernet port.

If the signal levels, logic and timing are compatible for the above use, I wonder if I could use one to connect my personal laser printer (not an all-in-one) to my network?

Both my printer servers are WEP only; new ones here are upwards of $80. I just moved into an urban environment where it's prudent to use better security.

Hey everyone,

I haven't posted on here in years, but could use some help now with the system that this board helped me build.

It's an ECS K7S5A AMD Athlon 1.14 ghz processor, I had 512mb of RAM
OS= XP Pro 2002 SP 3.

I had this unit in storage for about 18 months and just began using it again about 5 months ago. Before I stored it, I had installed a larger seagate HD which subsequently failed. I had to reload windows, and ever since then, my performance has been quite slowed, and I get these very short intermittent hangs when typing, searching pages, or watching youtube videos...pretty much everything. I figured it was a memory issue and bought a 1gb stick of RAM, now giving me 1.5gb. I just read maybe 5 minutes ago that the board capacity was 1gb. That change really didn't speed a whole lot up, but it did make some difference, though not enough to prevent the little 'hiccups'.
