What OS are you using? If windows 8 or 8.1 I would suggest you do not turn it off.

Are you running Command Prompt with administrator priviledges?

The Hiberfil.sys hidden system file is located in the root folder of the drive where the operating system is installed. The Windows Kernel Power Manager reserves this file when you install Windows. The size of this file is approximately equal to how much random access memory (RAM) is installed on the computer.

The computer uses the Hiberfil.sys file to store a copy of the system memory on the hard disk when the hybrid sleep setting is turned on. If this file is not present, the computer cannot hibernate.

To have us disable and enable hibernation for you, visit the "Fix it for me" section. If you prefer to fix this problem yourself, visit the "Let me fix it myself" section.

Just manually delete it, along with assumably your page file (i'm guessing you disabled paging too)
