How to Enable or Disable Hibernate in Windows 11
Hibernate in Windows 11 saves your computer’s current state to your hard drive, letting you resume exactly where you left off without using power.
This power-saving feature completely shuts down your PC, unlike Sleep mode which keeps your RAM active. It’s great for when you won’t use your computer for a while.
The hibernation file, called hiberfil.sys, can take up significant disk space, sometimes several gigabytes. Disabling hibernate can help you reclaim this space.
You enable or disable hibernate in Windows 11 using the Command Prompt (Admin) by typing “powercfg -h on” to enable or “powercfg -h off” to disable. Hibernate saves your session to the hard drive, allowing a full shutdown while preserving your work.
What is Hibernate?
Hibernate saves your open files and programs to your hard drive, then completely turns off your PC, using very little power.
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.
Things to Know About Hibernate
Hibernate in Windows 11 saves your open apps and documents to a special file, then completely turns off your PC. This uses no power, like shutting down, but allows for a much faster startup. The file it uses, 📁C:\hiberfil.sys, can take up a good amount of space on your hard drive.- 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. - If you turn off hibernate, Windows will delete this file to free up space on your hard drive.
- Turning off hibernate also disables a feature called fast startup, which helps your PC start faster after shutdown.
- When hibernate is off, you won’t see it as an option when you click the Power menu.
How to Turn Hibernate On or Off
Method 1Using Commands
- ⚙️ Requires Admin Privileges: Right-click the Start button and choose Windows Terminal (Admin) or Command Prompt (Admin).
- To turn on hibernate, type this command and press Enter:
powercfg -h on - To turn off hibernate, type this command and press Enter:
powercfg -h off - Close the terminal window when done.
Method 2Use Local Group Policy Editor
- ⚙️ Requires Admin Privileges: In the Local Group Policy Editor, navigate to
Computer Configuration\Administrative Templates\System\Power Management\Sleep Settings - Select “Specify the system hibernate timeout (plugged in/on battery)”
- Set it to Enabled and enter 0
Extra Tip: What if Hibernate Option is Missing?
Newer computers often use a feature called Modern Standby. This technology turns off the hibernate function by default. If you want to use hibernate but cannot find the hibernate option, you must first turn off Modern Standby. Changing Modern Standby off involves changing two specific system settings related to power management.
Summary
Turning on hibernate in Windows 11 lets you save all your open work and shut down your computer completely, using very little power. It’s perfect for when you’ll be away from your PC for a while, letting you resume exactly where you left off without draining your battery. Disabling hibernate frees up disk space but means you lose this quick resume option.- Hibernate saves your work and turns off your PC using very little power.
