Keyboard won't respond after power surge

I had three our four power surges, and my computer seems to turn on and work fine, as well as my monitor, but my keyboard is acting weird. I plug it in, and the lights flash, but after that, it doesn't respond. I don't know what to do. Is it fried?

It's possible the keyboard was damaged with the loss of power. Do you have another usb slot to try? You can try updating your drivers sure but there is no guarantee that will help either. If you want to do that try using an automatic driver updater. It will quickly identify your hardware and locate the proper drive for each device.click and get a free scan. I recommend scanning your system at least once a month to make sure your driver stay up to date

SOURCE: Flashing power button - no keyboard nor mouse. But PC works... ??

Yes, it may be that the +5v supply from the PSU is faulty, as the PS/2 ports run on 5v and USB runs on 9-12v. Replace the PSU with another of the same form factor and same power rating or better (>=230W). They come at ~£30, so not too expensive. For a little more. Try this:

SOURCE: Emachine with XP home edition doesn't start

Hi hearalso, down to the basic's. Replace power cord.
No help there than, remove the case's side panel to expose the motherboard. (Normally it is the left side panel while facing the front of the PC.)
Look closely for a small (green in color) led light. The power cord must be connected to the PC & connected to you're power strip but do not press the power on button on the PC.
The green led tell's you the board is receiving 5volts. Check all connections. Un-plug & reconnect every data & power connector in your PC. (Double check). There is a fuse inside your power supply that may have blown. Check you're manual page, Approva Statements B-1. Fuse Warning Instruction Caution.
Check fuse in power supply. (Unplug power cord before opening).
If you can not power up the PC after all of the above than if possible, swap out the power supply.
Replacing the power supply is the last step.

If you have more questions, feel free to ask.
Good Luck!

SOURCE: T6520 emachine. when i turn

Based on your previous troubleshooting, with both built-in video and alternate video card, I'd guess you have a bad mobo. Anything else that was wrong with it (RAM, CPU, etc) and you'd get beep codes.

Sounds like it's time for a replacement board. If the eMachine is out of warranty, it might make more sense just to go ahead and upgrade now, as they are so inexpensive. If you are capable of replacing the board yourself, that would be the cheaper alternative.

Hope this helps - remember to rate (and great troubleshooting, btw!)

Lookbook will not power on


A computer that won't start can be both alarming and infuriating, especially if you're on a deadline or you haven't been backing up all your data (like we all tend to do). Don't panic, though-this problem often has a simple solution.

1.If your desktop computer does nothing at all when you try to start it, first check that the power cable is securely plugged in at the back of the computer as well as into a working power outlet. It's amazing how often this is the case.
2.If you're starting from a button on the keyboard, make sure the keyboard is connected to the computer.
3.If the computer is plugged into a surge protector, see if the surge protector has a reset switch that you can push. (If it doesn't have a reset switch and the problem is with the surge protector, it will need to be replaced.) Try plugging a lamp or other device into one of the surge protector's outlets to make sure it's working.
4.If you can hear the computer's fan or hard-disk drive, or if you can see indicator lights on the main unit but the monitor stays dark, make sure that the monitor is connected to a working power source, that it's turned on and that it's securely connected to the computer via the video cable.
5.If the monitor and computer have power but the computer displays a "Non-system disk or disk error" message, check to make sure you didn't leave a disk in the A: drive. If you did, eject it and restart the computer.
6.If the operating system still won't start even though the computer and monitor have power, try restarting with a Windows CD-ROM in the CD-ROM drive or, if you've got a Macintosh, with a Mac OS disc in the CD-ROM drive. (You can start a Mac from the CDROM drive by holding down the C key while starting up.)
7.If the operating system then starts, your problem is probably with the startup hard drive or with the operating system installed on it. If you can't fix the drive, you'll have to replace it. (See also How to Fix Bad Sectors on a Hard Disk and How to Recover Lost Files.)

You can check it here as well:
The minute your computer's hard disk starts to act flaky, make sure you have an up-to-date backup. Then you can do some simple diagnostics and repairs. Both Windows and Mac OS come with built-in hard-disk utility software that scans your hard disk for errors and attempts to fix them.

1. Double-click on My Computer to open the My Computer window.
2. Select the disk that you want to diagnose and repair.
3. Choose Properties from the File menu. You should see the Properties window for the drive that you selected.
4. Choose the Tools tab.
5. Click the Check Now button under Error Checking Status.
6. Depending on your version of Windows, choose either "Thorough" or "Scan for and Attempt Recovery of Bad Sectors."

7. Click on Start.

I searched around on the web and found somebody mentioning the power source. I live in south Florida and we do get power surges almost daily. It seemed too good to be true but I decided to try it so I unplugged my monitor from my surge protector and plugged it into another outlet and BAM!!!!!! Crystal clear and like brand new!

It must have been the surge protector.

So if you have a fuzzy monitor one thing you CAN TRY is to change the power source or outlet. It worked for me and saved me a few hundred dollars.

Hi there,

First, check to make sure the power cable is plugged properly in the back of the monitor and into the surge protector. You can try a different power outlet, but if you're still having the same problem and the light isn't turning on, it's likely you've either blown the fuse inside the monitor, or you had a power surge and blown something inside the monitor. This happens when you don't use a surge protector and just plug the monitor into the wall.

That said, if the above doesn't work then you have a hardware problem with your monitor and it needs to be serviced.

Nothing works on my dell optiplex gx 270


First, are you sure the power supply is coming on? Check by placing your hand at the back of the computer where the power cord plugs in, turn on the computer and see if you feel air blowing. It sounds like your power supply died.

If you're not using a quality surge protector, you may have fried the PS. Wal-Mart sells a cheapie one that goes bad quickly. If you spend less that $39.95 on a surge protector, you're basically wasting your money.

If the power supply doesn't come on, replace it, but you'll have to purchase it from Dell because they use proprietary PS - so generic won't work.
