Hibernate is a Windows power feature that saves your current system state (including open documents and running applications) directly to your hard drive or SSD into a hidden file called hiberfil.sys, allowing your computer to power off completely. When you turn the machine back on, Windows reads this file and restores everything exactly where you left it.
Enabling or disabling this feature depends on your needs regarding storage space, drive wear, and convenience. Method 1: Use Command Prompt (Full Enable/Disable)
Using the Command Prompt is the most definitive way to manage the feature. Disabling it this way deletes the massive hiberfil.sys file and completely frees up disk space. Click the Start button and type cmd. Right-click Command Prompt and select Run as Administrator.
To Disable Hibernate, type the following command and press Enter: powercfg.exe /hibernate off Use code with caution.
To Enable Hibernate, type the following command and press Enter: powercfg.exe /hibernate on Use code with caution. Method 2: Use Control Panel (Show/Hide in Power Menu)
Sometimes hibernation is enabled on your system but doesn’t show up as an option when you click the Power button in your Start Menu. You can toggle its visibility through the Control Panel. Enable or Disable Hibernate in Windows 10
