Hi guys,

I'm working on a Toshiba Satellite A105 laptop. The laptop suddenly went dark while in use and now the screen stays dark. In a dark room, with a flash light on the screen, you can kind of make out a picture. I wanted to confirm that this is most likely a power inverter issue before ordering the part. If anyone could help i'd really apprecaite it, thanks!
**************SOLVED***********************:

Here is the solution for anyone interested: As I did some troubleshooting I found that the screen had a pinkish hue which an article mentioned that that usually means there is a problem with the BULB, not the INVERTER. What had me confused is that unplugging the cable from motherboard to inverter brought the bulb on for a second, but unplugging the BULB from the INVERTER did not bring the bulb on, so I thought 'maybe it is the power inverter.' I then took out the LCD monitor from an old dell laptop and hooked it up the the bad HP laptop with the HP'S POWER INVERTER to rule out whether it was the inverter or the bulb. Monitor came on just fine, which means the BULB WAS THE PROBLEM AFTER ALL, otherwise the bulb would flicker just like the bulb from the hp laptop did. Cheers!

I guess this can go in here since it is kind of hardware.

I am looking into buying a DC to AC power inverter to use in my car so I can watch DVD's on my laptop for long trips. I was wondering if anyone has ever used one of these, and how well they work.

I am planning on getting a 400 or 600 watt one. And I just want to run my ibook off of it.

Any personal experience and notes is appreciated, as I would like to get one soon.
 

A:Questions about DC to AC Power Inverter

Really need one that powerful for just a laptop - or are you going to run something else off of it. Now I'm not real sure on this but I've seen it with car amps, if you run something that powerful you could need a better alternator than a stock one? I had a friend once who when his camero would idle you could literally watch the voltage on the battery decrease, he had to actually drive to keep the battery charged with his speakers going.

Maybe Stormbringer will have a real answer.

Working on a client's problematic laptop...it is a Dell Inspiron 5105.

Laptop was having problems with being unable to power on, and with a darkening LCD when it did power on.

Disconecting the touchpad fixed the power-on problem.

However, the LCD continues to malfunction. I can't tell if the problem is with the inverter, the CCFL, or the LCD itself. The symptoms are as follows:

Sometimes, the screen works fine.
Sometimes, the LCD comes on, but the backlight does not.
Sometimes, the LCD does not function at all.
Video out to a CRT monitor works fine.

There seems to be no way of predicting whether the LCD/backlight will work or not. Just, sometimes it does, and sometimes it doesn't. I've checked to be certain all the connections are secure...

Unhooking and rehooking the connections seems to make little difference. I've reseated the inverter and CCFL, which also seems to make no difference.

Any ideas as to which of the four--inverter, CCFL, LCD or (detachable, ATI) video card--is the problem? Or know how I could determine which it is?

As mentioned before, the computer would not boot reliably until the touchpad was disconnected. Is it likely these two problems are related somehow? I've been assured the laptop did NOT take a lightning strike, but i have only the client's word to go on for this.

ACDelco 100W Power Inverter
100 watt continuous output
Power Surge up to 260 W
Built in fan for cool running

Got so I can use notebook computer in car.

Are these safe to plug notebook computers into? Any assistance appreciated. Dorothy
 

A:ACDelco 100W Power Inverter

I've been using a ninety-five-watt version for about a year now with my Averatec loptop without detectable adverse effects. Mostly, I use it for charging; but, I have on rare occasions used it to run the system.

To be sure yours in sufficient to run the laptop you could monitor the state of the laptop battery's charge to see if it looses, gains or stays the same.

Example: If your laptop needs 130 watts and the inverter puts out 100 watts, your battery would slowly drain and the inverter would run hot and maybe fail after a while.

Frankly, I don't undertsand why so many people spend a hundred dollars or more for a twelve-volt power supply they can plug into a cigarette lighter when they can get one of these inverters for around 20 dollars or less. I got a package of two nintety-five-watt jobs for $20 at Sam's Club. That's only $10 each.

I have an HP DV9000 which had no picture on the LCD. Well, it had a picture, but it was very, very faint as if the back lights were dead. Works fine when plugged into VGA or if you squint/shine light to see the actual screen.

So I replaced the screen with my friends old screen from the identical model, assuming the backlights are part of the screen assembly. Apparently not, because it didn't take care of a thing.

So then I figured it must be the power inverter. Replaced that, too, and exact same problem.

What could possibly be wrong? I know how to replace the parts, I did it right. I can still faintly see. Is the backlight a separate part from the screen? Why else would I have no light at all? I know his screen and inverter work fine.
 

A:Screen and power inverter replaced, still nothing.

Is the laptop motherboard supplying the correct operating voltage and dimming control signals into the backlight inverter?

And yes, the backlight lamps are built-into the LCD panel itself. They have their own power cables and connectors for attaching to the inverter.

Hi guys,

I recently posted about trying to troubleshoot a power inverter vs a backlight. With some troubleshooting and help I was able to trace it to the backlight.

Now I've run into a slightly different problem. The screen is black (very dim and even looking at it in the light its hard to see the icons but you can very barely make them out). When I press the standy switch by the monitor it flashes on for a second with perfect colors (NOT purplish like in most ccfl bulb issues).

I took another ccfl bulb just to hook it up and the bulb did the same thing, flickers on and off. I hooked the laptop up to an external monitor and it works just fine (if i press standy I can see it going into standby on the external monitor).

I would say it is the power inverter at this point but would like a second opinion Thanks!

Hi,

I am looking for a backup solution for my desktop computer (read as: tight budget) which can notify through a software interface about time remaining till batteries run out.

I am trying to run a server on this machine which I'm planning to use to give a demo to some parties from remote location. So basically this desktop will be unattended. I have written a small utility to gracefully shut down the server in case of power failure so that it doesn't look as though it crashed . And this utility needs to read the time remaining till total shutdown from somewhere. So I am looking for a budget backup solution which can provide me this data. (It is doesn't need to log it or so, I'm just happy to scoop it from its process memory if I have to.)

Can you guys suggest any backup-solution or anything which can help me find the time remaining till this desktop shuts down, if running on backup power?

cheers

I'm about to go on vacation with my family and decided to bring my laptop along to keep myself entertained on the long car ride. My laptop only has a 4 hour battery and it's an 8 hour trip. So I bought a 12V to 120V power inverter so I could plug it into the cigarette lighter to power it. However, I noticed that the cigarette lighter port provides 120W of power and the inverter is 160W. My laptop only needs 90W to run (according to the manual). My question is: is it safe to use a 160W inverter when the power port only provides 120W? Would I just get the reduced wattage instead of the full 160W or will something fry when the inverter tries to pull 160W out of a 120W outlet?

Thanks to all in advance.

I have a Toshiba Laptop... A week ago, my screen has started going black and coming back. Just two days ago, my screen went black and did not come back. I thought my screen was dead but then I figured that the back light of my screen was gone because when I look at the screen carefully, I barely see the things on my desktop....When I turn on my laptop, I can see my screen for 3-4 seconds, then it goes black again. Same thing happens when I log on after log off... It again gives me the light about 3-4 seconds after just logging on, then it goes black again. I finally opened up the screen, and found the display inverter... and it again gives me the light 3-4 seconds after I plugged out and plugged in the inverter cable. I am not sure whether the problem is the inverter itself of the inverter cable. I really need help.
 

A:Distinguishing between display inverter and inverter cable problem.

It sounds like the inverter may be sensing an overload on its output(s) and shutting down after a few seconds. Some possible conditions causing it could be 1) the backlight lamp(s) failing, 2) arching of the inverter output cable to itself or the frame of the LCD panel, or 3) a failure of the inverter's overload sensing circuit that makes it think it is being overloaded, when it really isn't.

WARNING: Use extreme caution when working around a CCFL inverter with power applied to it. Portions of it will have hundreds of volts of electrical energy on it. You could receive a nasty (and possibly fatal) shock if you come in contact with the high voltage.

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.

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.

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 bought a Dynex USB 2.0 4-Port Hub last week and have decided to add an external power supply to power the hub.

Radio Shack would be a good place to start although you might have to get one of their adjustable models. A Google search should also turn up something.

A:Power adapter

Hi SUSMI,
The system is designed to support both 45W and 65W adapters - see the specifications here - http://dell.to/2fhPLIf
When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point.
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.These are onboard diagnostics and they might possible pick some error if the hardware is not functional.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.

Hello aaronbaron,

Reseat the power adapter just means make sure the power adapter is plugged in good on the laptop and the wall outlet. I would try powering off the laptop, unplug the power cord, take the new battery out. Reinstall the new battery only and try to power on the computer. If that does not work plug in the power cord and power up with the new battery installed.

http://siliconrepublic.blogspot.com.au/2011/02/arduino-based-pc-ambient-lighting.html

It says I need a 12V DC supply for powering the breadboard. When searching up for 12V DC supplies, I only get power supply's that plug into the wrong wall socket (I live in Australia).
Do I need to get something like the article suggests:
http://www.amazon.com/Garmin-AC-Veh...1KZ6/ref=sr_1_2?ie=UTF8&qid=1297231222&sr=8-2

Or can I get something such as this:

If the first option is the only possibility, how do I get the plug to go into my wall socket?
Also, how do I get the other end plugged into the breadboard when the product just has a single plug on the end?
 

A:What type of power adapter do I need?

You can use the Ebay adaptor, the easiest way to get 2 wires is to get a socket that fits the plug, like this one :- http://www.ebay.com.au/itm/5-5-x-2-...05?pt=LH_DefaultDomain_15&hash=item4167b5b34d and solder 2 wires to that socket.

The circuit at your link uses a 2 wire plug into the breadboard, you would have to get a similar plug OR you could push bare wires into the breadboard.

OR you could cut the plug off to reveal the 2 wires but they will probably be quite thin and may not connect well if pushed into the breadboard holes.

Sounds like the Centre pin has broken away and lodged itself in the plug. I cannot tell you which is positive and which is negative with regards to the rings on the plug.

I'd prefer to have an actual duplicate, not another brand thats just generic and cheap. On Toshiba's website the replacement is $89.00.

Hi everyone.

I know that this is not really entirely related to a Windows 7 computer and especially to these forums, but I really need some advice on this and it would be great if anyone who has experience in voltage, amps and safety for laptop power adapters would be perfect.

My friend has just traveled down to my house for a week but has foolishly forgot his plug for the power socket on his power adapter. He uses this for his computer. Again unrelated becuase it is an Apple 45W MagSafe2 adapter.

So I was wondering if he could simply use a cord like this one below to plug into the adapter?
The black cord is 2.5A 250V~

The adapter is 100-240V~ 1A

These are both for input.

Any help would be greatly appreciated .

A:Power Adapter Problem

That white 'thing' appears to be for an Apple Macintosh MacBook/MacBook Pro [I have a MacBook Pro] and you might not be able use the black cord due to fit, the V-shaped notch in the black plug would have to let it be inserted. But it probably won't hurt to try as it's still a 110/120Volt source.

The MacBook power adapter also came with a piece that replaced that cord and has the prongs to plug directly into a wall socket/extension cord, maybe it's in his Notebook bag.

I recently purchased a Del Latitude 7202 Toughbook.
At same time purchased 12V power adapter.
The adapter was shipped separately.  SKU 469-4546.  The power plug did not fit computer.
It is too fat.  Spent 4 hours with tech support and they told me the wrong part was shipped.
They said they would send a replacement.  10 days later I get a package with an HDMI cable in it.
Call support back, was told they would just issue me a credit and I can purchase one online.
I was told I needed part.  450-AAYR.  Web page for that part lists the 7202 as compatible.
It arrived yesterday.  Still doesn't fit.  I am returning it as well.  
What is required to get the correct part?

Hello!

I received the following message when I am booting up my Dell ATG Laptop. Does this mean I need a new power cord? If so, is there anywhere recommended to purchase or do I just go to the dell website?

The AC Power Adapter Wattage and Type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. Please connect a Dell 65W AC adapter or greater for best system performance. To resolve this issue, try to reset the power adapter. Strike the F3 key (before F1 or F2 key) if you do not want to see the power warning again.

Strike the F1 to to continue. F2 to run the setup utility, Pree F5 to run onboard diagnostics.

I have a Inspiron 15 3541 touch screen and "misplaced" my power cord and adapter. I'm using a Dell adapter from a different computer, but when I turned on my laptop, I get a message requiring a system or admin password even before it boots up. Is this because of the different adapter? How many pins did my adapter have? What problems does a different adapter create?

A:Power adapter pins

The password that is showing up before your computer boots sounds like there is a BIOS password set on the computer.  Unfortunately if you don't remember that password then you are probably stuck.  You can probably go online and search and see if there is a way to reset BIOS on the laptop and get it to default and remove the password that is set on it.  If there is a hard drive password though then the only way to remove that if you forgot it is to install a new hard drive as the password will follow the drive, not the computer.
Your power supply should have only 1 pin.  Dell used the same adapter for their computers for a while, they come in different wattage though and if you use an adapter that is too low then it may not be able to charge the battery while you use it or at all.  If the plug fits and it is a Dell charger you should be okay to at least get the computer up and running.  If it is a low wattage charger and the setting is set in BIOS (usually is by default) you'll get a message from your computer telling you that the charger isn't powerful enough to charge the battery while in use.

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?

thanks

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.

It's an hp 6720s 13 months old, XP Home, HP 65W power adapter.

Laptop running fine on battery only. Laptop runs fine when battery removed and power adapter is connected. Laptop does not run fine when battery and power adapter connected - 100% CPU.

Also, the charge indicator light no longer works and the power icon does not show that the battery is charging, although it is.

I've updated the BIOS, restored factory power settings and tested the power adapter during startup and have the same prob with the CPU usage.

What could cause the power adapter to use 100% CPU? Please let me know if you need more info, cheers.

I have a 90w power adapter from an older notebook that will work with my HP DV5-1015nr. I transport my notebook between home and office. I'd like to utilize the older power brick, so that I won't need to transport a power brick back and forth. The tips on both adapters, of course, are of a different diameter.      My multi-tester identifies that the tip is hot for both adapters. The problem I have is that the older power brick has two wires: core wire (+) and shield (-), and the newer power adapter has three wires: shield that is connected to the core of tip (+), black that is connected to outer part of cylindrical shaft that must be the ground, and white connected to inner part of cylindrical shaft (also negative?). So do the black and white wires on the newer adapter need to be soldered to the shield on the older one?   

A:Wiring for Power adapter?

Just a guess, since it is 90watt, they may have run the extra wire to carry the load, shield is always much larger than center tip wire. Did you measure voltage and ploarity of all three connections with the brick plugged in? Tip is always + and ouside is always - on a HP, not sure what the third is, see if there is any voltage on it, It could also be some sort of sensor wire for the charging system on the mobo. Better to buy another adapter than smoke the motherboard on the lappy taking a chance. If you want to chance it just connect the two wires that are on the center and outside. Leave the 3rd odd one unconnected. probably can be found used for cheap.

Though I had posted this previously, but cannot find it anywhere!

Got an Altec Lansing Multimedia Computer Speaker System ACS41. Apparently they were used on a Gateway 2000 PC.
However, the power adapter was lost.
The speakers do not have any electrical specs on them regarding voltage, amps, and polarity.

Anyone have a similar set of speakers, or,
know of any way this type of info can be found out, in order to get the right power adapter for them. Do not care to fry them with an overkill. The speakers probably came with PCs running Windows 98SE, or Windows Millennium.

Prefer not to go to Radio Shack, they normally are rather expensive, and the people who own this do not want to go that route.

My neighbour was given a second-hand computer and asked for my help setting it up.

It is a Dell Optiplex 755 running Win7.

Currently installed graphics is NVidia Quadro FX 3500.

I looked up the service tag and this is not the original card (Original was ATI HD2400XT).

The issue I have is that the FX3500 is an 80W card, with the PCI-E slot having a max of 75W. On booting I get low power warnings from the NVidia card.

The card has a 6 pin PCI-E connection available for the additional power, but the PSU has no PCI-E power cable.

The only free power cables from the PSU are a couple of 15pin SATA cables. I have seen adapter cables for 15pin SATA to 6 pin PCI-E. Are these any good for my situation?

If not, what are the alternatives? New PSU? Different GFX card?

The Yoga 3 Pro power adapter looks like a normal USB brick, and the cord looks like USB, except with a kink in the connector at the Yoga 3 Pro end. Can I charge my phone or tablet with it?

A:What's with the Yoga 3 Pro power adapter - it's a ...

Yes the Yoga 3 Pro power adapter is a USB charger too!
 

How does it work?

The special "fool proof" charging cord has two extra pins on the AC adapter end and two extra pins on the Yoga 3 Pro end. The extra pins only make a connection when the fool proof cord is plugged in to the Lenovo charger and the Yoga 3 Pro. When a regular USB cord is plugged into either the charger or the Yoga 3 Pro, it makes a regular USB connection.
 

Can I charge the Yoga 3 Pro with any USB charger?

No. The Yoga 3 Pro requires 2A at 20V, which is what the provided 40W Lenovo AC adapter supplies.
 

Can I charge a USB device with the Yoga 3 Pro AC adapter?

Absolutely. In addition to 2A at 20, the Yoga 3 Pro AC adapter supplies 2A at 5.2V (10.4W), enough to charge a phone or tablet. Works for iPad.
 

Where can I buy spare AC adapters and cords?

AC adapters with cords are sold in the accessories section of the Lenovo store.
 

Where do I find the part numbers for the AC adapter and cord?

Look for AC Adapters In the PDF Yoga 3 Pro Hardware Maintenance Manual.
 

What are the USB specs of the Yoga 3 charging port?

It's a USB 2.0 port. It provides enough power to charge an iPhone, but not enough to charge an iPad. If you want to charge an iPad, try the USB 3.0 port on the right of the Yoga 3 Pro.

So.. I see this problem has been posted about before, so I just wanna know what my options are.
This problem actually popped up on me a few months ago, but I was able to remove and insert the power cord a few times and the message would go away and I would be able to charge my battery. But as a month or two passed, it became more finicky, and I had to jiggle with it a little more, but still, I was able to charge my battery and use my laptop wire-free.
Now today, I've been trying all day, and cannot for the life of me get the battery to charge. I get the following message when I plug the wire in.
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation."
Also, I think its worth nothing that a lot of people mention that this error message comes up while they are booting their Laptops, mine only comes up once Vista is loaded and I attempt to reinsert the cord.
So, I have tried another Dell charger, a 90W one, and the same problem does occur (My original is a 65W). I am planning on getting a different battery tomorrow to see if it is the battery, as this ones usable life was getting quite low, down to barely a half hour per full charge.

I ignored this problem for awhile by just hitting F1. However, within the last month, it has gotten worse.

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.

Hi there forum,

I just bagged an Lcd monitor for nowt but have no power supply for it.
The rear panel says 12V 3.0A DC power supply, but I can't find any of this type, I've tried Maplin, play.com etc and all they suggest is 300mA, now I thought 3.0 A was 3000mA?

Do I need to go back to electronic school basics?
Thanks

The section of my adapter has frayed near the point where it plugs in and I have to practically baby it to keep it charging. This is a huge problem, especially considering that I'm planning to go off to college soon. There's so many counterfeits on the market, and I'm afraid that I may get one that'll just give me grief. In middle of the school year I may not even have enough to buy a new cord, so this is a big deal for me. Yes, I have looked it up and what came up were forums about how to avoid counterfeits, which served to confuse me. While they recommend that buyers should avoid "marketplace" retailers like Amazon, Sears and Ebay, they don't exactly say where exactly to go. There's a bunch of shady websites besides these retailers and I'm not really finding anything too solid at a more legitmate distribution channel...  Of course I'm willing to spend some money. It's just that the 40-70$ price tag I've been seeing for the cord on relatively trustworthy sites seems steep, especially considering that I got the laptop (power cord incl.) for 200$ a few years back. It hasn't given me any trouble, but it's hard to justify spending ~25% of its original value on a cord. I want to spend something from 20 to 30$.  Thanks for the help!

I have the 5110nr, I believe. It's got the GTX960m. I am a tech with over 35 yrs. exp in building and overclocking. I realized that the stock charger seems underpowered, at least the one I received with this unit, which I bought used "like new" on Amazon for $850. I was somewhat let down initially upon testing the system for performance, then I found it would double it's performance when on battery power. This indicated to me that the unit was able to draw more current from the battery than when plugged in. Having an understanding of power requirements and electronics, I realized the unit may benefit from using a higher wattage power supply. I bought this baby intending to run "Project C.A.R.S." which is purportedly the most advanced racing sim ever made, with awesome graphics blowing away all current Xbox/PS4 etc. platforms. I found I could run it reasonably well on battery power with the system dialed in using Intel Extreme and PrecisionX for pushing the CPU & GPU to their comfortable limits. Also something I've learned over the years is it's generally best to use the true HP drivers for GPU, manufacturers tend to custom tweak a given driver for their specififc model giving it the best performance even though the revision is never near the most current. Now, the big reveal... I decided t take a chance and buy a used 230watt HP power supply for $38 amazon, then splice the cord so the power adapter would fit this model. I went from not being able to charge while plug... Read more

I need a new AC power adapter for my monitors. I have three Acer S243HL LED monitors, and the power adapters basically exploded a few months ago (I heard a loud pop, followed by the monitor just turned off). I tested it with a working power adapter (the one I'm using now for my only functional monitor), and the monitor itself is fine. The power adapter is not.

Anyways, to prevent this happening in the future, could someone recommend to me a high quality power adapter which won't short out on me?

The power adapter that I'm using looks like this

A:Looking for a high quality AC power adapter

I think there is no such thing as a high end power adapter, you could buy one with goldplated pins and from a quality brand, but the thing is not to let them get very hot and take good care of them, apart from that i dont know any

Hi -

First post for me - but what a helpful site!

I have a Linksys WRT54GX, ver. 2, wireless G router to which I have lost the ac power adapter. The manual lists it as a 12 volt DC 1 amp (12VDC 1 A).

I have been to Radio Shack, Best Buy, and numerous electronic outlets, as well as exhaustive searches on the net, as well as contacting Linksys directly (they will not sell one separate! Imagine that for tech support!).

You guessed it - I cannot find one. I even went to my pack rat brother who probably has beat Noah and has collected at least one, if not two of everything on Earth - just in case, as he says!

Anyone have any idea where I can get one of these things?

The ones I have found are 12VDC but .5a, 1.something amps, but none are 1 amp.

Anything anyone can chime in on would be appreciated.

(No there is no USB connection on the router to draw power from the CPU, either! Darn!)

Thanks

Noel in Northern NY!

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?

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

Seeing as my PSU is limited in the cable department i had to purchase a 4 pin to 8 pin adapter to power my PC.

Do i have to connect both the 4 pin and molex cable's to it or is it ok just connecting the molex cable like i have done?.

A client brought a laptop to me, saying his daughter had spilled a little bit of water on it, not a lot though. He said one of his dogs eat through the power supply cable and it is sellotaped up, but he said it does work on the charger. However, he came over with it, and I tried it with the charger plugged in, came on for about 10 seconds, no beeps or anything, could hear the hard drive and fan working, but then it went off again (worked on it in my conservatory). I took it in to my home office, tried it, didn't even start up! Not even the light saying it's charging! However, when I put the power cable in, sparks came off it. Because I am not very dexterous, my mate who normally helps me with these things is on holiday.
However, as he said it worked fine on the charger before, it's probably not the laptop. He also said that the laptop doesn't work without the charger plugged in.
Question now is: Should I get a new charger? (While transporting the laptop, a component in the psu might have gone)
It is a Logiq M76T, and it is less than a year old.
(I got told the PSU's made in China don't last long!)
 

A:Dog ate Logiq M76T power adapter

Definitely start with the adapter. Once you rule that out as the culprit you can move on the the psu or motherboard.
