How to Enable or Disable Hibernation on Windows 7

Do you want to learn how to disable hibernation on Windows 7? On this post, I will show you some easy ways to disable hibernation.

Hibernation is a state in which you can put your computer instead of turning it off or putting it to sleep.

When the computer hibernates, take a capture of your system files and drivers and save that capture to the hard drive before it is turned off.

This allows your computer to boot faster because it doesn’t need to reset those files or settings.

Hibernation on Windows 7 is a featured enable by default and doesn’t harm your computer, so it isn’t necessary to disable it, even if you do not use it.

However, when hibernation is enabled, this function reserves some system space for that file “hiberfil.sys“, that is allocated to 75% of the computer’s RAM.

If you have 8GB of RAM, your hiberfil.sys file will take 6GB of your hard drive’s storage space; If you have 16GB of RAM, your hiberfil.sys file will take 12GB.

Therefore, the main reason why you would like to disable hibernation on Windows 7 is if you need those gigabytes of space on your hard drive.

Method #1: CMD

When you want to disable hibernation on Windows 7, using the Command Prompt may be the easiest way to it.

To do that, follow these simple steps:

  1. Click on the Start Menu to open the Search box and there write the word: CMD
  2. It will appear in the results a program named Command Prompt, right-click on it and select the option Run as Administrator
    command prompt administrator
  3. A black window will open, once on the Command Prompt you only need to copy and paste the following command to disable hibernation: powercfg /hibernate off

As easy as that you can disable hibernation using the Command Prompt if you want to reenable hibernation follow the same steps but this time use the command: powercfg /hibernate on

Method #2: Control Panel

If you don’t want to use the Command Prompt to disable hibernation, you can also do it from the Control Panel, to do that follow these easy steps:

  1. Click on the Start Menu to open it and then click on Control Panel

Method #3: Registry Editor

The Registry Editor let you change several things on your computer, and somethings can harm your system stability or even broke your computer.

  1. Open the Run window pressing the keyboard shortcut: Winkey + R
  2. In the window type the command: regedit
  3. Press Enter or OK to open the Registry Editor
  4. Once there, go to the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
  5. There, change the values ​​of both HiberFileSizePercent and HibernateEnabled to 0.
    registry editor
  6. After making the changes, close the Registry Editor and restart your computer.

When your computer boots you, hibernation will be disabled entirely on Windows 7, so the only way to reenable will be following these same steps.

Hibernation vs Sleep

When you sleep the computer, the computer automatically goes to a mode of minimum power consumption, only the one you need to keep the RAM on.

In that RAM the current state of the system is stored, so that when you return you will find all the windows and apps that you had open as they were

If you have a laptop with a good battery, it can last for more than a day like this without running out of juice.

When you use hibernation mode almost the same happens, the difference is that instead of storing the current state of the device in RAM, it is stored on your hard drive or in solid storage.

This means that energy consumption will be zero. A hibernating computer is turned off, doesn’t consume power because it doesn’t need to keep any components on.

Sleep the computer is like a deep sleep while hibernating is more like a cryogenization.

What consumes hibernation mode is disk space. Windows hibernation file can occupy a few gigabytes of space, and in addition to this, when you wake up a computer from hibernation the process is usually a little slower than when you wake it from a suspension, although this also depends on the speed of your disk.

Wrapping Up: Disable Hibernation on Windows 7

If you always turn off your computer or never do it, you can disable hibernation to gain some extra disk space. In my Windows 7 32-bit, with a 300GB hard drive, disabling hibernation saves more than 3GB of disk space.

It may not seem like much, especially given the current capabilities of hard drives, but if you don’t need to Hibernate, why not enjoy this free space?
