Question: Ok, so I know what hiberfil.sys is, and I want to use hibernation on my laptop.

But I have another hard drive active in my laptop, it's taken from my old one... and I want to get rid of the hiberfil.sys on that drive. But even with admin privileges I can't delete it.

Any ideas?

Answer: 
To delete restore file you can open command prompt with admin privileges and run command

```
powercfg -h off

```

Then reboot, and Windows should automatically delete your `hiberfil.sys`. If it doesn't, you can remove it manually.

Then running

```
powercfg -h on

```

restores sleep and hibernate functionality.

You can start command prompt with admin privileges by starting command prompt (`Windows Key`+`R` (Run), type `cmd`) and then right-clicking command prompt icon on task bar and selecting "Run as administrator".
**Right click the drive**, click **Properties**, and go to the **Security** tab.

Use the **Edit** button to give **Full control** to Users and Authenticated Users.

After that, you should be able to delete the file via the command prompt (make sure that you're using the correct current directory):

```
del /f hiberfil.sys

```

That should get rid of the file. I recommend changing the permissions back afterwards.
