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.

types de mise en veille
In the actual Sleep mode, the computer doesn’t turn off completely and still uses a lot of energy to power the RAM. Monitor and hard disk are turned off, but as soon as you touch the mouse, the computer wakes up.
Hibernate means that the computer essentially turns off, but first the RAM is saved on the hard drive. When you reboot the computer, the RAM is loaded from the hard drive, so that you can continue where you left. This procedure can take a minute or two. (mode S4)
Hybrid Sleep is a mix of sleep and hibernate. The computer will go into sleep mode, but it will also save the RAM to the hard disk. If the battery runs out or power fails while during hybrid sleep, the computer will reboot as if it had been in hibernate. (mode S4)
