PURPOSE

You need to troubleshoot your computer because it isn't powering up.

PROCESS

1. Check that all cables are securely plugged into the back of the computer and monitor.
2. Check that the power cables are plugged into a power socket and the socket has been turned on.
3. Try using a different power socket or, if you are using a power extension cable, plug the power cable directly into a power socket in the wall.
4. Replace the power cable with one that you know works.
5. Check if there are any lights on the front of the computer.
   • If there are lights on the machine but not the monitor, it's probably a monitor issue.
   • If there are lights on the monitor but not the computer, it's probably a computer issue.
   • If there are no lights on anything, then it may be possible there is a local power outage.
6. With laptops, try removing the power cable and battery.  Hold down the power button for about ten seconds, and plug the battery and power cable in again.  Press the power button to see if it switches on.
