I've put windows 7 on a fairly old machine of my Dad's, though it runs quite happily. To save him time booting I tried to get him to use hibernate (which he hadn't used on this machine previously (with XP)). However, the machine regularly wakes itself up. I've disabled wake for all the hardware that supports it in Windows (keyboard and mouse), not that I think they would wake it from hibernate. I've also disabled all wake options in the bios. Still it does it. Any ideas?
