DISABLE HIBERNATION IN WIN8, WIN7

HOW TO DISABLE HIBERNATION IN WIN8, WIN7?

What is hiberfil.sys

Windows has two power management modes that you can choose from: 

Sleep Mode - it keeps the PC running in a low power state so you can almost instantly get back to what you were working on. 

Hibernate mode - it completely writes the memory out to the hard drive, and then powers the PC down entirely, so you can even take the battery out, put it back in, start back up, and be right back where you were.

Hibernate mode uses the hiberfil.sys file to store the the current memory state of the PC, and is managed by Windows, so you can’t delete the file.

Disable Hibernate on Windows 8, Windows7

open command prompt in  administrator mode by right-clicking on the command prompt in the start menu, and then choosing Run as Administrator. Type in the following command:

powercfg -h off

You will notice that the Hibernate option is gone from the Shut down menu.
