Windows 2000 is the first Windows to support hibernation at the operating system level (OS-controlled ACPI S4 sleep state) without special drivers from the hardware manufacturer. A hidden system file named " hiberfil.sys " in the root of the boot partition is used to store the contents of RAM when the computer hibernates.
The Windows power management system is based upon an idle timer. If the computer is idle for longer than the pre-set time, then the PC may be configured to sleep or ' hibernate '. Windows uses a combination of user activity and CPU activity to determine when the computer is idle.

The most common cause of problems with power saving and hibernation on Windows systems is an incompatible device driver.
