How to Enable or Disable Hibernation

Hibernation copies your computer’s memory to the hard disk so that the computer can turn off without shutting down completely. After you’ve put your computer into hibernation, starting it back up only takes a few seconds while it reads the contents of memory from the hard disk.

Hibernation is VERY useful. Unfortunately, it consumes disk space equal to the memory in your computer. I have 2GB of memory in my laptop, so keeping a hibernation file uses up 2GB of valuable disk space. Because of this, many people choose to turn hibernation off.

Here’s the catch: Windows Vista doesn’t provide a user interface for turning hibernation back on after you’ve turned it off (wha…?). Fellow MVP Alun Jones discovered this and found the solution: an administrative command prompt. These are documented in Microsoft Knowledge Base article 920730, How to Disable and Renable Hibernation on a Computer that is Running Windows Vista. Here are some easier instructions, though:

To disable hibernation:

Click Start. Type powercfg /hibernate off.  Press Ctrl+Shift+Enter.

To enable hibernation:

Click Start. Type powercfg /hibernate on.  Press Ctrl+Shift+Enter.

A command prompt will appear and disappear. The program doesn’t give you any feedback anyway, so you’re not missing anything.

Yes, I really do love the new Start menu, and that Ctrl+Shift+Enter shortcut to run a program as an Administrator.

why does microsoft have to make things sooooo complicated!!!!!

I understand that sleep mode is better because you do not have to have 2 gb available on your hard drive but if you have a laptop and you want to turn off the power in order to move it around and then turn it on and keep on working you really need hibernation why make it so unintuitive how to turn it on or off?????!!!!!!!!
