Don't worry. Here comes your help. There are several causes that your desktop PC failed to wake up, such as the Sleep key on your keyboard is configured incorrectly. It is also possible that you are running Windows Vista and have not updated to Service Pack 1 or a later version. You can try to press the Sleep key again, or you can click the Power Management to verify that the Allow this device to wake the computer is enabled.

All you need to prepare is a workable USB and another PC for this. Your USB will be made into a bootable media to wake up your PC. Its data will be erased, so get a backup in advance.
