Home computer will not turn on

I tried unplugging it and plugging it in numerous times through a working surge protector and wall outlet (socket). It does not get any power when I push the push button switch on the computer.

    Same exact thing happened to me. But there is a green light in the back of the power supply flashing. What does that mean? I unplug it and it still flashes.!? Does my power supply still work? Is it something else maybe?

If your computer was left on was off when you got back to it, and will now no longer turn back on, i can say with 80% confidence that you need to replace your power supply. They are usually about $50 at any computer shop. If you don't feel like doing the replacement yourself you can have a shop do it or circuitcity or best buy.

faulty surge protector
They are useless after one power surge and the breaker is probably reading the faulty earth leakage from the protector
logical that it the oven works anywhere but trips on the protector , then the protector is faulty

Locks frequently and restarts sometimes all by itself. Parts of the screen regularly skews in triangular shapes.


  • Verify that the power outlet you're using is good and your power cable is firmly connected to the wall outlet-if using a surge protector, be sure that it's firmly plugged into the wall outlet. Also, try temporarily plugging directly into the wall outlet to eliminate any issue with the surge protector; plug a different electronic device into the same wall socket to make sure the socket works, and also try the iMac's power cable in a different wall outlet.
  • Make sure the computer's power cable is firmly connected to the computer.
  • If any external devices are connected to your iMac, disconnect them and try to turn the computer on again. If the iMac will power up when those devices are removed, but not when they are connected, contact the manufacturer of those devices for assistance.
  • Try resetting the iMac's SMC
  • Remove and reinstall the SO-DIMM memory modules, located in the bottom of the computer.
  • Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve

    1. Shut down the computer.
    2. Unplug the computer's power cord.
    3. Press and hold the power button for 5 seconds.
    4. Release the power button.
    5. Attach the computers power cable.
    6. Press the power button to turn on the computer.

Unplugged my 32LV67U to vacuum behind it and now it will not power up. Yellow LED keeps blinking and I waited several minutes but tv will not power up. Worked perfectly until I unplugged it. Called...


That wall outlet may have frequent surges so try another wall outlet see if it turns back on. If it turns on be sure to use a surge suppressor and never plug the TV directly into the wall outlet. The AC surges will kill the power supply of the TV in short time. See if there's a kill-switch near the ac adapter of the TV if there is turn it on.Get a surge protector/suppressor then try plugging it back in the wall. If still no power then the power board is already damaged, you can send the board too me and I'll repair it for you or seek your local repair center.

Dell C640 will not power up w/ac ad


  1. Verify that the AC adapter brick is receiving power.
    Shut down the computer and unplug the adapter from the system first and then from the power socket. Wait 5 seconds.
  2. Plug the adapter directly into the wall socket, bypassing surge protectors, UPS units, or extension cords. The adapter LED should produce a steady green light.
  3. If you do not get a green light, try the adapter in another wall outlet in another room or verify that the first outlet works with a lamp or hairdryer.
  4. You can also isolate the power problem to a bad adapter by swapping it out with a second adapter - such as one for use with the port replicator.
  5. If the adapter LED lights, check the computer for bad connections.
  6. Examine the system power socket to be sure it does not have any bent, missing, or pushed-in pins.
  7. Plug the adapter connector directly into the computer, bypassing surge protectors, extension cords, etc. Be sure that the adapter connector fits tightly into the computer's power socket.
  8. If you have access to another computer like yours, try your adapter on it or its adapter on your computer.
  9. If your computer is still under warranty and the AC adapter does not respond to troubleshooting, please contact your computer manufacturer.

Can't turn wii back on


Did you unplug it from the Wii, or from the Wall Outlet? You need to unplug it from the wall outlet, not the Wii. If you haven't unplugged it from the wall outlet and left it unplugged for 5 to 10 minutes, then unplug it from the wall outlet and leave unplugged for a good 5 to 10 minutes.

This is a common problem with the Wii. Even if it's hooked up to a surge protector. If there was a power surge, or the power went out, etc...anything, this will happen. The problem is with the AC adapter, not the Wii itself, so power to the AC adapter needs to be cut off.

There is a circuit inside the AC adapter that needs to be reset. Unplug the AC adapter from the wall/surge protector outlet. Don't unlpug it from the Wii, it has to be at the outlet. You have to kill power to the adapter.

Unlpug it from the wall/surge protector outlet, and leave it unplugged for 5 or 10 minutes. This will kill power to the AC adapter, and give the circuit time to reset. When you plug the adapter back into the outlet after 5 or 10 minutes, the red led on the front should be lit up.

Everything is plugged in, and it wont turn on


It seems even 5th or 6th problem is this. The AC adapter needs to be reset. Unplug it from the wall outlet for 5 to 10 minutes (NOT from the Wii, it HAS to be from the wall outlet).

Considering how often I see this problem, I'm amazed Nintendo didn't address it in their FAQ on the Wii.

This is a common problem with the Wii. As I said, I'm very surprised Nintnedo didn't cover this in the owners manual FAQ, considering it happens almost every time there is a power surge or the power goes out, etc.

Even if it's hooked up to a surge protector, this happens. Power comes back on, but the Wii appears dead. It won't turn on, and the LED indicators won't light. If there was a power surge, or the power went out,etc...anything, this will happen. The problem is with the AC adapter,not the Wii itself.

You need to reset the AC adapter to get the Wii to work again. There is a circuit inside the AC adapter that needs to be reset. Unplug the AC adapter from the wall/surge protector outlet. Don't unlpug it from the Wii, it has to be at the outlet. You have to kill power to the adapter.

Unlpug it from the wall/surge protector outlet, and leave it unplugged for 5 or 10minutes. This will kill power to the AC adapter, and give the circuit time to reset. When you plug the adapter back into the outlet after 10 minutes, the red led on the front should be lit up.

32 '' CRT won't turn on afer power surge


Follow these steps to troubleshoot the television not turning on:

Make sure the AC power cord is connected securely to a working wall outlet.
NOTE: If the television is plugged into a power strip or surge protector, unplug it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

Press the POWER button on the television.
Press the POWER button on the remote control that was supplied with the television.
NOTE: If the television turns on and off using the POWER button on the television but does not respond to the POWER button on the remote control, troubleshoot the remote control.

Unplug the television power cord from the electrical outlet for 30 seconds.
Plug the power cord back into a known working electrical outlet.
Attempt to turn on the television.
IMPORTANT for the following models only:

KDF-E42A10
KDF-E50A10
KDL-V26XBR1
KDL-V32XBR1
KDL-V40XBR1
Unplugging the above television models from the electrical outlet may only be a temporary fix. The problem may reoccur after several months of use. To completely resolve the issue, a software update is available.

For all other models, service will be required if the troubleshooting steps do not resolve the issue.

Tower won't turn on


Brandi,

Please check the following:

1. Make sure the the surge protector is securely plugged into the wall. Test this by plugging in a light / lamp to it, to make sure it's working.
2. Make sure that the surge protector is turned on.
3. Check to make sure that the power cable from the computer to the power surge protector is securely plugged in.
4. Check to see if the computer will power on now.

5. If this still isn't working, remove the power strip/surge protector and connect the computer directly to the wall.

6. If this STILL isn't working, try plugging your computer into a different outlet in the house to see if the outlet in your home might be bad.

6. If your computer STILL isn't powering on then I'm afraid the worse has happened, which is one of the following issues:

1. Bad power supply (they are cheap, around $20-40)
2. Bad motherboard (they are sort of pricey, around $50-200)
3. Bad CMOS battery (they are cheap, around $5-10)

I can fix all of the above and order parts for all of the above, if you are in need of parts.

I hope this troubleshooting guide helps you! If this resolves your issues, please mark this question as resolved and select my answer. This will assure customers that I can help them with their issues.

Thank you,
