How to Enable/Disable Hibernation in Windows Vista

Advertisements

When Windows is switched to hibernation mode, Windows saves the current state into a file called hiberfil.sys. This files size is very huge and will extend to several GB. In case you are not using hibernation, you can disable it to save hard disk space. To disable hibernation, open Start-> All Programs-> Accessories-> Command Prompt. Right click and select Run as Administrator in case you are not logged in as admin account.

In the command prompt type “powercfg.exe –h off” to turn off hibernation (without quotes).
