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.

Re: Home computer will not turn on

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.

Today we lost power to our home. Blinked first then dimmed and then went out completely. When power was restored, I tried to turn my computer on but the switch light would not come on. No power except...

If the computer was not plugged into a surge protector the computer could be damaged. If it was plugged into into a surge protector see if there is a reset on the surge protector .Try unplugging the computer for a few minutes and the plug it in again and try it. You can try plugging the computer into a different outlet that you know is working(without the surge protector). If you look on the power supply there may be a reset inside the case.
If nothing works you may have only burnt out the power supply in the computer, you could try another power supply from another computer to see if it is just the power supply. If still not working you would have to test and trouble shoot all your parts to see what is damaged.

My daughters xps 200 won't start, she presses the button and nothing. She has checked the surge protector that it is pluged into and it is OK... is there a reset button is there was a power surge??

most surge protectors have some sort of on/off switch and a reset button. If there was a surge then you would need to pres the reset button to get the surge protector to function again. If there was no surge then try using the on/off switch on the surge protector to see if that helps. Also try simply unplugging the power cord from the back of the desktop while the computer is turned off. This will sometime also help.

Tower won't turn on


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,

It wont turn on

Try changing your power supply, in saying that: I assume you checked the obvious; plug at the wall and at the back of the computer, another wall socket, remove the computer from any power strip or surge protector (as they could be defective).

No power to a SR1420NX.

Power supply light on or flashes Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure: CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
  1. Disconnect everything from the computer, including the power cord.
  2. With the power cord disconnected , press the power button on the front of the computer for five seconds. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps. NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply
  3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America. Performing this step ensures that the voltage switch is engaged and set correctly for your country/region. Figure 4: Voltage selector switch c00517964.jpg Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
  4. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
  5. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it. NOTE: If you find the device that was causing the problem was a surge protector, resetting a breaker or fuse on the surge protector may fix the issue.
  6. Remove all attached devices except for keyboard, mouse, and monitor.
  7. Remove any internal component that was recently added, such as video card, memory, CD, DVD, and hard drives. An added device may take more power than the power supply is rated for. If the problem goes away when the component is removed, the only option is to upgrade the power supply to power supply with a higher wattage rating.
  8. Check the power switch:
    1. With the power cord disconnected, press the power button on the front of the PC. The button should release easily and not stick in the socket.
      • If the button sticks, it should be replaced or serviced.
      • If the power button does not stick and appears to be functioning, continue using these steps.
    2. With the power cord disconnected, remove the case or side panel.
    3. Follow the wires from the power button on the front of the computer to their connection on the motherboard.
    4. Look at the power switch cables connected to the motherboard. If the cable has become disconnected, connect the power switch cable connector to the connector on the motherboard. Figure 5: Power switch connector on Motherboard c00517968.jpg
    5. Replace the side panel, plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.

Last night I turned-off my PC througg Windows and when I pushed the power button this morning nothing hapened. There is no sign of "life" from the PC.

Check the power source to the computer (both ends of the cord), if a surge protector is in line with the power , remove it and plug the computer straight into the wall. also check the wall plug with a lamp or something to ensure power there. make sure the switch on the power supply hasnt been changed to the 220v side.
If no power at the wall- check your breaker box in the house
If it works plugged straight into the wall- check the surge protector
If power at the wall and plugged straight into the computer (no surge protector) and nothing lights up when you turn it on- have your power supply checked.

Computer power won't turn on

First thing to do is try to plug the pc in another wall socket to see if it goes on, If not, the MB could have gotten fried, even though the other plugs seem to work. Hopfully you just need another surge protector as that could have gotten damaged.

How old is your computer? Did you recently have a power outage or anything? Most the time if a computer won't turn on, something in it went bad OR an outlet is bad. Try this:

1. Make sure that the power switch is on, the switch in the back (on the power supply itself) is turned on, and everything along those lines is functioning.
2. If that doesn't work, and it will not power on AT ALL, make sure the cords are plugged firmly in place, including the surge protector and/or the power cord itself.
3. Try resetting the surge suppressor and/or plug the computer into a different outlet in the surge suppressor. Try other items in that surge suppressor (or even in the wall outlet, if that's what you're plugged into) to make sure that the outlet itself is working.
4. If your computer is plugged directly into a working wall or surge suppressor outlet, try a different power cord.
5. If your surge suppressor works, your wall outlet has power to it, and you are using a known-good power cord in the computer, you will have to go into more in-depth investigation as something inside the computer likely went bad. It could be the video card, motherboard, CPU fan, power button, or the power supply itself. Start by testing the video card and the power supply by (one at a time) swapping out a known-good component for the one you suspect may be bad. If it won't turn on after that, try swapping out the next and try it again. If it still will not work, it could be something more serious such as the motherboard or power button.

Good luck!

it could be a bad power supply or a bad motherboard. Other problems might cause issues, such as a bad video card.
