How Can I Turn Off Hibernation?

Hibernation is a feature that allows your system to shut down quickly and save everything that is open in the RAM to be stored on the hard drive until the computer is powered on again.

Windows XP and Windows 2000 use a file called hiberfil.sys to save everything it needs when they go go into hibernation. If you never use the hibernate function, you can turn it off.

When this feature is disabled, the hiberfil.sys file is deleted. This can free up the as much disk space as the amount of ram that you computer has. For example, if you have 1GB of RAM, you could be freeing up to 1GB of hard drive space.

In Windows XP, go to Control Panel > Power Options > Hibernation and uncheck / Enable hibernation.

In Windows 2000, go to Control Panel > Power Options > Hibernate / tab and uncheck / Enable hibernate support.

If you should want to re-enable hibernation, go back in and check / Enable hibernation in XP or Enable hibernate support in Windows 2000.
