Disable Vista’s Hibernation

Windows hibernation is a feature that lets you store your computers memory to the hard disk then enter a sleep state to conserve power. But it uses a lot of hard disk space in the process up to your amount of ram, if you have 2 gigs of ram your Hibernation file can grow up to 2 gigs. If you don’t use this feature you can turn it off and save valuable disk space. My Hibernation file is .99 gigs right now.

So lets disable that Hibernation file,

  1. Click Start. Type powercfg /hibernate off Press Ctrl+Shift+Enter.
  2. Approve the UAC if prompted.
  3. A small command window will open for a second then disappear and then Hibernation will be disabled, and your Hibernation file will be deleted.

If you want to enable it again.

  1. Click Start. Type powercfg /hibernate on Press Ctrl+Shift+Enter.
  2. Approve the UAC if prompted.
  3. A small command window will open for a second then disappear and then Hibernation will be enabled again.

      Yes I am wondering since I just found this file if I delete it through the disk cleaner it says if I delete the file it would disable hibernation. Now does that mean I can’t use hibernation ever or do I have to re-enabled it again?

      @ Michael, I believe Vista will recreate the file after a reboot as long as you don’t run the switch powercfg /hibernate off .
