Win 10 will not disable hibernate

I am trying to get rid of the hiberfil.sys file, with no luck.

I tried turning off hibernation in the Settings, with this guide

Turning off "Allow hybrid sleep" did not change anything. Windows doesn't remove the file, and I am not allowed to remove the file.

Typing the powercfg.exe -h off command also did not change anything. I get an error, Windows doesn't remove the file, and I am not allowed to remove the file.

C:\Users\Cogni>powercfg.exe -h off

Unable to perform operation.  An unexpected error (0x65b) has
occurred:  Function failed during execution.

I tried restarting the computer, still nothing works.

How do I fix this?

Solution 1:

Hibernating needs to be off, and only an administrator can change that setting. Then you need to restart to remove the OS's lock on the file, and after the restart, the file is gone.

Solution 2:

Right click Command Prompt and then click Run as administrator. Or we could disable it through Control Panel\All Control Panel Items\Power Options\Edit Plan Settings\Change advanced power settings:

Solution 3:

In most cases the actual reason of Unable to perform operation [...] Function failed during execution error is that being member of Administrators group is not enough. You have to intentionally run Command Prompt as Administrator.

When searching for "Command Prompt" from Start menu, select "Run as administrator" from the right side options. Click on it and when terminal window pops up - you should be able to see "Administrator: Command Prompt" in the window's title bar.

Enter the powercfg.exe -h off command again - now it should turn the hibernation off without 0x65b error.

Solution 4:

A bit late I know but if you are wondering:

Open a command prompt as an admin and type powercfg /h on

And if you want to revert back: powercfg /h off
