PC or laptop is off

Desktop Computer

If your desktop computer isn't powering on there is a few things you can check before you go out and buy a new Power Supply. If all of these fail, try getting a new Power Supply to see if it solves your problem. If it doesn't then contact your manufacturer.

* Make sure the power cable from the computer to the AC outlet is plugged in at both ends.
* Make sure the monitor's power cable is also plugged in and the monitor is turned on.
* If the computer is plugged into a power strip or surge protector, make sure the light is on and it is powered on.
* Check that the AC power from the wall is working. Try plugging something else into the socket instead of the computer. If there's no power, check for a blown fuse or circuit breaker.
* Look for an on/off switch on the computer's power supply and make sure it is flipped on.
* Try a different power cord.

Laptop Computer

A laptop may not power on due to a bad battery or an AC adapter. Try these things and see if it helps. If none of them help, you may need to replace your battery or AC adapter.

* If you're trying to run a laptop on battery power and it doesn't power on, make sure that a battery is in the battery compartment.
* If the battery is in place, try connecting the AC adapter. If that solves the problem, recharge or replace the battery.
* Make sure the AC adapter securely plugged into the computer and into the wall outlet.
* If the computer doesn't work or the battery doesn't charge when the AC adapter is plugged in try plugging in the AC adapter with the battery out. If you get no power then you probably need to replace the AC adapter.

If the AC adapter powers up the laptop but does not charge the battery then you should replace your battery. Check the manufacturer or a local store.
