Windows 7: Hibernate - Enable or Disable

   Information

Hibernation is a power-saving state designed primarily for laptops. While sleep puts your work and settings in memory and draws a small amount of power, hibernation puts your open documents and programs on your hard disk, and then turns off your computer. Of all the power-saving states in Windows, hibernation uses the least amount of power. On a laptop, use hibernation when you know that you won't use your laptop for an extended period and won't have an opportunity to charge the battery during that time.

This tutorial will show you how to enable or disable hibernate and restore or delete the hiberfil.sys file in Windows 7 and Windows 8.

When hibernate is disabled, the Hibernate option is missing from the Start Menu (Windows 7 only), Shut Down Windows dialog, Power menu (Windows 8 only) and the Advanced Power Plan Options.

You must be logged in as an administrator to be able to do the steps in this tutorial.

   Note

• By default, the size of the hidden protected OS hibernation file (C:\hiberfil.sys) is 75% of the total amount of installed RAM on your computer.
• In Windows 7, you can set your computer to either use or not use the Hybrid or Hibernate sleep mode option from the Advanced Power Plan Options.
• In Windows 7, you will only see Hibernate listed in the Start Menu power button arrow menu if you have Hybrid turned off in the Advanced Power Plan Options.
• Windows 8/8.1 PCs with InstantGo don't have the hibernate option
• If you disable hibernate in Windows 8 and 8.1, then it will also disable fast startup.
