When hibernation is initiated, Windows automatically writes the complete state of physical memory (RAM) to the hiberfil.sys file on the hard drive before the system powers off. This process requires no user configuration and happens unconditionally whenever hibernation is used. Upon next power-on, Windows restores memory from this file, returning the system to exactly the state it was in before hibernation.

Data is saved to the hard disk (hiberfil.sys), not to ROM, which is non-volatile read-only memory that cannot be written to by the operating system at runtime.

Hibernation always saves data automatically without requiring any special configuration; there is no setting that must be enabled to trigger the memory save.

Hibernation specifically prevents unsaved data loss by persisting the full memory state to disk before shutdown, unlike a sudden power loss or a standard shutdown.
