I was running around all over Vista trying to get my Hibernation mode back on - since for some strange reason it disappeared all by itself. An even stranger thing is that I could not pinpoint where the setting which controls it really is. I knew it was around Power Configuration somewhere but dammit - no sign of it for me tonight.
It turns out there's a really easy way to do this, so if you want to turn the hibernation on or off, simply do the following:
1. Click Start, All Programs, and then right click on "Command Prompt".
2. From the context menu click on "Run as administrator".
3. If User Account Control prompts you to allow the action, click on Continue.
4. In the command prompt window, type "powercfg –h off" (or "on" without the quotes) followed by Enter button.
4. Close the Command Prompt window and you're done :)
