The Windows hibernation, unexpected error (0x65b) is mainly because you dont have access to turn off the file. Most times you want to save space as your hard driver is full. In order to get around this if you dont use hibernation on your computer then you can turn off hibernation and save about 3GB of space on your “C” drive which is normally your main drive. Below you will see how to turnoff the hibernation without an error.

If you are trying to get rid of the hiberfil.sys file, with no luck then this is how to to turn off the file. Most will be receiving this error when they try and use the
powercfg.exe -h off command with nothing changing. The error will normally look as follows:

- Type in command in the Windows Taskbar
- Click on Run as Administrator
- The Command prompt then opens
- Now type in the following line
powercfg.exe -h off
- The system will now delete the file as you have administrator privileges.
- Check your hard driver space as it will not show about 3GB of additional space
- You can turn on the file again if you want instead of OFF type in |ON
