Windows Help says that in order to enable Hibernate I need to open Power Options and select the 'Hibernate' tab. Actually I already knew that, so the question is: What do I have to do to enable the 'Hibernate' tab in the Power Options? I'm pretty sure this quation has been asked before but I can't remember the answer. OS = Windows XP-Pro x64. CPU = G840 RAM = 4 GB Plenty of room on the hard disk.
