Windows Tip: How to Disable Hibernation in Vista

Hibernation has got to be one of the good things that Windows offers for mobile computing. But if you don’t have a real use for it, then why not just turn it off. While there are some good things about it – not losing what you’re doing when you need to shut your computer down – there are some kinks to it that I don’t like to deal with. Like the hibernation file taking as much space as you have physical RAM. And I have 2GBs of RAM and only 120GBs of hard drive space and I’ve actually used a great deal of that. Another 2GBs of data just to store a current session isn’t too attractive at all.

With Vista, there are two ways to disable hibernation. Pick your poison.

Via Disk Cleanup

  • Click Start and type disk cleanup and hit Enter
  • Select All files from this computer (be sure to have administrator privileges here as User Account control will bug you)
  • Select the drive where Vista is installed
  • Wait for Vista to finish scanning the files
  • Check the Hibernation File Cleaner option then click OK (just take note of the other options that are checked)
  • If prompted to delete files, click the Delete Files button

Via Command Prompt

Now I clearly don’t get it why disabling Hibernation doesn’t appear in the Power Options but you can do a manual override via command prompt.

  • Click Start then type command prompt, right-click on the icon and select “Run as Administrator”
  • Acknowledge the UAC prompt
  • In the command prompt window, type powercfg –h off
  • Close the command prompt window

    You don’t have to type ‘command prompt’ you can simply type ‘cmd’. Just an FYI

    by the way you can type ‘powercfg -h off’ right into the vista start menu search and hit enter and it will automatically launch CMD, works with other command line commands also
