I use Hibernate all the time when complete shut down is not wanted. Very often after a while on hibernate, my computer suddenly switches on by itself. I am using Windows XP. This is not good at all, since I may be away for a while and the purpose of hibernate is to put the PC into an almost no-power state whilst retaining screen data. If it switches on, then I may as well have left it on in the first place. Has anybody a clue how to stop this ?
