Water damage to laptop

Thanks for the solution! Let's say that it has shorted the power supply, what should I do next? Do I need to replace the a/c adapter?
The green light is still on the adapter but i'm not sure if this means its still working... please advise... thanks..

Power supply damaged, Can I replace it with any other model power supply?


A standard ATX PS won't fit in your low profile case. The plug types can be different too. Usually there's a schematic with a PS that describes the wire color of each voltage. So you could conceivably shove the pins out of one PS plugs and insert them into the different plug, or solder the wires to the correct pins, and leave the PS outside of the case.

try to unplug it fromt he back of your pc and open the side of your case and unplug the 2 or 3 onnectors going fromthe power supply and wait 10 or so minutes amnd plug them back in and see if that changes it if it powers back on that meant it has shut off either due to a short circuit and the system killed power to protect the system from damage or the system has overheated

Computer won't turn on after short in electrical circuit


Hi:
You might just need the power supply on your computer tower replaced. It is about $40, and not that hard to swap out. Most computer stores will test it for you for free too. If they test it and its good, then you might have further damage to your tower from the power problem, but the power supply would be the most likely problem

Two months old dead no power


Hi there,

Check the Power cable of your PC for any damaged or burn/cut. Firmly check the connection on the slot of the CPU Power Supply,

Check the Electrical outlet , or better plug the cord on a different electrical outlet.

If all of this has nothing to do and the problem was still there, possible problem on the powersupply are, it is advisable that you have to replace this part, a possible burnt or a short circuit has happen inside, due to some electrical malfunction on your area.

HOpe this helps.

Let me know for any clarification

Fix graphics card on Dell Dimension E510


something on the motherboard may be damaged, if you replaced a power supply the motherboard really needs to be checked to see if there is any damaged components on it. my best guess is there are damaged components on it and you may need a new motherboard as well

HELP! No video on Sony Vaio VGC-RA710G desktop


Since the power supply wasn't secured properly it actually contacted the motherboard while it was still carrying a charge. For next time, I use zap straps for all of my wires and to secure components. Try removing the motherboard and doing the power supply self test, most likely you will have to replace both the motherboard and CPU though.

A looping beep


Try disconnecting power to all your drives. It's possible one of the drives has a short that is bringing down the power supply (most power supplies will shut down if they sense a short, to avoid damaging your computer). If it's not that, it's either a bad video card (reseating obviously won't help if the card's damaged) or a bad motherboard or processor. If you have another machine you can borrow a video card out of, you can test that. Otherwise, you'll have to replace the motherboard and processor. Never replace just one of the two, as one can damage the other and it's not worth frying your new equipment by putting damaged hardware in.

The flashing power switch and power supply LED on the rear in conjunction with a power failure or surge indicates that there is a defective component; typically the power supply, motherboard, memory, processor or modem. -Disconnect all the power supply leads, drives, and motherboard as well as any USB, firewire and other external devices. -Plug in the 115v power supply cable and look at he LED on the back of the power supply. If it is still flashing the power supply is bad and needs to be replaced. -If it isn?t flashing then unplug the power supply plug in one device, plug in the power cord and watch for the flashing LED again. If it?s flashing you?ve found your culprit, if not move on to the next component and repeat the process until you?ve found it. Don?t forget your plug in cards could also be the problem. Good luck and let us know if you have any other questions. As always please don?t forget to rate this posting.
