Disable Hibernation in Windows Vista

Windows places a file on your hard drive that it uses when your computer goes into hibernation mode. If you do not use hibernation mode, you may want to disable hibernation and clear the file off your hard drive to free up some space (the file will use as much space as you have in physical memory, so if you have 1GB of RAM, it’s going to use 1GB of your hard drive space).

There are two ways of disabling it:

Method: 1) To disable Hibernation using Disk Cleanup

1. Click Start >> All Programs >> Accessories >> System Tools >> Disk Cleanup
2. If prompted to choose a drive, select the drive in which Windows Vista is installed onto and press OK.
3. Disk Cleanup will scan the hard drive and present you with a list of options.
4. Check “Hibernation File Cleaner”, and then click OK.
5. When asked “Are you sure you want to permanently delete these files?” click on the Delete Files
button.

Method: 2) To disable hibernation using the Command Prompt

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” (without the quotes).
4. Close the Command Prompt window.
