Hibernation is a power saving option which was designed primarily for laptops. Unlike “sleep mode” which puts the open documents and files into the memory, hibernation puts all the open files and documents on to the hard disk and shuts down the computer without drawing even a small amount of power. Thus hibernation becomes an excellent way to save power and resume Windows back to the state where it was left off.
