I never understood the theory of why people even use hibernation. I have this debate with my users at work all the time. They undock, leave their desk to walk 50 feet to a conference room and they think they are saving battery by hibernating.

Personally I never turn my computers off. I'd rather let them run than boot every day and spin the hard drives. They have fans to keep them cooled, no reason to hibernate. I DO use a screen blanking screen saver on the laptops. On the desktops I just power the monitors off. Don't see a reason to hibernate, move all that cached data from RAM to hard drive and back again.
