Hibernate is a useful power-saving feature in Windows 11 (and Windows 10) that lets you completely power off your computer while preserving your current session. When you turn your PC back on, Windows restores your open programs, files, and documents exactly as you left them, allowing you to continue working without reopening everything manually.
Many users enable Hibernate to save battery life on laptops, while others disable it to free up storage space used by the hibernation file (hiberfil.sys). In some cases, the Hibernate option may also be missing from the Power menu, leaving users unsure how to enable or disable the feature.
In this guide, you’ll learn what Hibernate does, how it differs from Sleep and Shutdown, how to enable or disable Hibernate in Windows 11, and what to do if the Hibernate option is missing from your PC.

What Is Hibernate in Windows 11?
Hibernate is a power management feature that saves the contents of your system memory (RAM) to a file called hiberfil.sys on your storage drive and then completely turns off the computer.
Unlike Sleep mode, which keeps data stored in RAM and continues to use a small amount of power, Hibernate uses no power after the PC shuts down. When you start the computer again, Windows loads the saved session from the hibernation file and restores your apps, files, and windows to their previous state.
Hibernate can be particularly useful for laptop users who want to preserve battery life while keeping their work intact. It is also helpful when you won’t be using your computer for an extended period but don’t want to close your applications or lose your current session.
Some Windows 11 devices have Hibernate enabled by default, while others may have the feature hidden or disabled depending on the hardware configuration and power settings.
Sleep vs Hibernate vs Shutdown: What’s the Difference?
Windows 11 offers several ways to power down your PC, but each option works differently.
Sleep
Sleep mode keeps your current session stored in RAM and puts the computer into a low-power state. Your PC can wake up almost instantly, making Sleep ideal for short breaks. However, because RAM remains powered, the computer continues to use a small amount of electricity or battery power.
Hibernate
Hibernate saves your current session to the hiberfil.sys file on your drive and then completely powers off the computer. Since the PC is fully shut down, it uses virtually no power. When you turn the computer back on, Windows restores your previous session so you can continue where you left off.
Shutdown
A normal shutdown closes all running programs and completely turns off the computer. When you start the PC again, Windows performs a fresh boot and you must reopen your applications and files manually.
| Feature | Sleep | Hibernate | Shutdown |
|---|---|---|---|
| Saves Open Apps and Files | Yes | Yes | No |
| Uses Power While Off | Low | None | None |
| Startup Speed | Fastest | Fast | Slowest |
| Best For | Short Breaks | Extended Downtime | Fresh System Restart |
If you frequently switch between work sessions and want to save battery life without losing your progress, Hibernate is often the better choice than Sleep.
How to Enable Hibernate in Windows 11
If the Hibernate option is disabled on your PC, you can enable it using a simple Command Prompt command. Once enabled, you’ll be able to add Hibernate to the Power menu and use it whenever needed.
Method 1: Enable Hibernate Using Command Prompt
- Press Windows + S and type cmd.
- Right-click Command Prompt and select Run as administrator.
- In the Command Prompt window, type the following command and press Enter:
powercfg /hibernate on - Wait for the command to complete.
- Restart your computer if required.
After running the command, Windows will create the hiberfil.sys file and enable Hibernate support on your system.
Verify That Hibernate Is Enabled
To check whether Hibernate is active:
- Open Command Prompt as administrator.
- Run the following command:
powercfg /a - Look for Hibernate in the list of available sleep states.
If Hibernate appears in the available power states, the feature has been successfully enabled.
How to Add Hibernate to the Power Menu in Windows 11
Even after Hibernate is enabled, the option may not appear in the Start menu Power options. This happens because Windows allows Hibernate to be enabled on the system but hides it from the Power menu.
You can manually add the Hibernate option by changing the power button settings.
- Press Windows + R, type control, and press Enter.
- Click Hardware and Sound > Power Options.
- Select Choose what the power buttons do from the left pane.
- Click Change settings that are currently unavailable.
- Under the Shutdown settings section, check the box next to Hibernate.
- Click Save changes.
After saving the changes, open the Start menu, select the Power button, and you should see Hibernate listed alongside Sleep, Shut down, and Restart.
If the Hibernate checkbox is missing, make sure Hibernate has already been enabled using the Command Prompt method shown above.
How to Disable Hibernate in Windows 11
If you never use Hibernate, you can disable the feature and remove the hiberfil.sys file from your system. This can free up several gigabytes of storage space, especially on computers with a large amount of RAM.
Disabling Hibernate will also remove the Hibernate option from the Power menu.
Disable Hibernate Using Command Prompt
- Press Windows + S and type cmd.
- Right-click Command Prompt and select Run as administrator.
- Type the following command and press Enter:
powercfg /hibernate off - Close Command Prompt.
Windows will immediately disable Hibernate and delete the hiberfil.sys file from your system drive.
Verify That Hibernate Is Disabled
To confirm that Hibernate has been turned off:
- Open Command Prompt as administrator.
- Run the following command:
powercfg /a - Check the list of available power states.
If Hibernate no longer appears in the list, the feature has been successfully disabled.
What Happens When You Disable Hibernate?
Disabling Hibernate does not harm Windows 11 or affect normal computer operation. Your PC will continue to work as usual, but you will lose the ability to save your current session and restore it after powering off the computer.
Here are a few things that happen when Hibernate is disabled:
- The Hibernate option is removed from the Power menu.
- Windows deletes the hiberfil.sys file from the system drive.
- You may recover several gigabytes of storage space.
- Open applications and documents will no longer be saved through Hibernate.
- You’ll need to use Sleep, Restart, or Shut down instead.
For desktop computers with plenty of storage and constant power, disabling Hibernate usually has little impact. However, laptop users who frequently travel or rely on battery power may find Hibernate useful because it allows them to resume their work without draining the battery.
If you later decide you need the feature again, you can re-enable Hibernate at any time using the Command Prompt method described earlier.
How to Fix Hibernate Option Missing in Windows 11
If you can’t find the Hibernate option in Windows 11, the feature may be disabled, hidden from the Power menu, or unavailable because of certain system settings. Try the following fixes to restore it.
Fix 1: Enable Hibernate Using Command Prompt
The most common reason the Hibernate option is missing is that Hibernate has been disabled.
- Open Command Prompt as administrator.

Should You Enable or Disable Hibernate in Windows 11?
Whether you should enable or disable Hibernate depends on how you use your computer.
Enable Hibernate If:
- You use a laptop and want to conserve battery life.
- You frequently leave multiple applications and documents open.
- You want to resume your work exactly where you left off after powering off the PC.
- You often travel and need a way to save your session without draining the battery.
Disable Hibernate If:
- You never use the Hibernate feature.
- You need to recover storage space on a drive with limited capacity.
- You prefer performing a full shutdown when you’re finished using your computer.
- You use a desktop PC that remains connected to a constant power source.
For most laptop users, keeping Hibernate enabled can be beneficial because it provides a balance between convenience and power savings. However, if storage space is more important than the feature itself, disabling Hibernate is a simple way to free up and reclaim disk space.
Frequently Asked Questions (FAQ)
Yes. Disabling Hibernate is completely safe and does not affect the normal operation of Windows 11. The only downside is that you will no longer be able to save your current session and resume it after powering off the computer.
Disabling Hibernate does not significantly improve system performance. However, it can free up storage space by removing the hibernation file (hiberfil.sys), which may be helpful on devices with limited disk capacity.
The size of the hiberfil.sys file varies depending on your system configuration and installed RAM. On computers with large amounts of memory, the file can consume several gigabytes of storage space.
The Hibernate option may be missing because the feature is disabled, hidden from the Power menu, or unavailable due to certain hardware, driver, or firmware configurations. Enabling Hibernate with the powercfg /hibernate on command usually resolves the issue.
Windows does not normally allow the hiberfil.sys file to be deleted manually while Hibernate is enabled. The proper way to remove the file is to disable Hibernate using the Command Prompt command: powercfg /hibernate off This automatically deletes the file from your system drive.
Sleep stores your current session in RAM and uses a small amount of power to keep it available. Hibernate saves the session to the hard drive or SSD and completely powers off the computer, allowing you to resume your work later without using battery power.
