How to Enable or Disable Hibernate in Windows 11

What is Hibernate?

Hibernate saves your open files and programs to your hard drive, then completely turns off your PC, using very little power. When you press the power button again, Windows reads that saved state back into memory and puts you where you were.

Hibernate is especially useful if you won’t use your laptop or tablet for a long time and won’t have a chance to charge it. Sleep slowly drains the battery because it keeps RAM powered. Hibernate does not.

Things to Know About Hibernate

This mode uses zero power while letting you resume your work much faster than a normal boot, though the system file can take up a lot of storage space.

Before you change anything, here is what happens when you switch hibernate on or off:

• Windows saves hibernate info in a hidden file called C:\hiberfil.sys. This file usually takes up about 40% of your computer’s RAM size. On a PC with 16 GB of RAM, that is several gigabytes on your system drive.
• If you turn off hibernate, Windows will delete this file to free up space on your hard drive. You get the space back right away, and you can turn hibernate on again later to recreate the file.
• Turning off hibernate also disables a feature called fast startup, which helps your PC start faster after shutdown. Fast startup relies on the same file, so if you care about quick boots, think twice before turning hibernate off.
• When hibernate is off, you won’t see it as an option when you click the Power menu. If hibernate is on but the option is still missing, open Control Panel, go to Power Options, click Choose what the power buttons do, then Change settings that are currently unavailable, and tick the Hibernate box under shutdown settings.

How to Turn Hibernate On or Off

Method 1Using Commands

1. ⚙️ Requires Admin Privileges: Right-click the Start button ⊞ and choose Windows Terminal (Admin) or Command Prompt (Admin). If Windows asks whether you want to allow the app to make changes, click Yes. A terminal window opens with a prompt. Make sure it is the administrator one, because the commands fail with an access error in a normal window. This works the same on Home and Pro.
2. To turn on hibernate, type this command and press Enter:
   
   powercfg -h on
   
   The command normally prints nothing when it works. The prompt simply returns, and Windows creates the hibernation file.
3. To turn off hibernate, type this command and press Enter:
   
   powercfg -h off
   
   Again, expect no message. Windows deletes the hibernation file, and fast startup is disabled with it. Use only one of these two commands. To undo your change, run the other one.
4. Close the terminal window when done. Restart your 🔄 computer so the change is fully applied, then check the Power menu to confirm Hibernate appears or is gone, depending on which command you ran.

Method 2Use Local Group Policy Editor

1. ⚙️ Requires Admin Privileges: Open the Local Group Policy Editor, then navigate to Computer Configuration\Administrative Templates\System\Power Management\Sleep Settings. This editor is only included in Windows 11 Pro, Enterprise and Education. On Windows 11 Home it is not available, so use the command method above instead.
2. Select Specify the system hibernate timeout (plugged in/on battery). Double-click it to open its settings window.
3. Set it to Enabled and enter 0, then click Apply and OK. A timeout of 0 means Windows never hibernates automatically. Note that this policy does not delete the hibernation file, so it will not free disk space. To undo it, set the policy back to Not Configured. Restart your 🔄 PC afterward.

Extra Tip: What if Hibernate Option is Missing?

Modern Standby (a power state that keeps your PC connected to the network while asleep) turns off the hibernate function by default on many newer computers. If you cannot find the hibernate option in your power settings, you need to change your system power configuration to bring it back.

The usual fix is to run the turn-on command from the Command Prompt section above in an administrator terminal, then restart. After that, check the Power menu. If Hibernate is still not listed, tick the Hibernate box in Power Options as described earlier. On some hardware the manufacturer blocks hibernate entirely, and you may need a BIOS or firmware update.

Summary

Choosing to turn on hibernate windows 11 gives you a fast way to resume your exact workflow, while turning it off frees up valuable disk space on your hard drive.

The main points to remember:

• Hibernate saves your work and turns off your PC using very little power.
• It's great if you won't use your device for a while and can't charge it.
• Turning off hibernate frees up disk space but disables fast startup.
• You can turn hibernate on or off easily using commands, from an administrator terminal. Run the opposite command any time to undo it.
