Enable or Disable Hibernate in Windows 11

Hibernate is a power-saving state designed primarily for laptops, and might not be available for all PCs. 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 to the hiberfile (C:\hiberfil.sys), and then turns off your computer. Hibernate uses less power than sleep and when you start up the PC again, you’re back to where you left off (though not as fast as sleep). Use hibernation when you know that you won’t use your laptop or tablet for an extended period and won’t have an opportunity to charge the battery during that time.

  • PCs with Modern Standby do not have hibernate available.
  • By default, the size of the hidden protected OS “C:\hiberfil.sys” file is 75% of the total amount of RAM installed on your computer.
  • If you disable hibernate, fast startup will also get disabled.
  • If you disable hibernate, hibernate will no longer show in the Power menu.

Fast startup requires that hibernate be enabled. If you only want to use fast startup and don’t plan on using hibernate, then you can specify the hiberfile type as reduced to significantly reduce the size of the hiberfile (C:\hiberfil.sys) to about half of its full size.

If you want to use hibernate, then be sure to specify the hiberfile type as full.

This tutorial will show you how to enable or disable hibernate and restore or delete the hiberfil.sys file in Windows 11.
