ABSTRACT:
A power saving process in a computer system that can be suspended, allowing for immediate restoration of an operating state just before the power saving process without waiting for completion of the process. During the power saving process, the contents of the main memory are saved to a hard disk drive in memory block units. Every time the saving of a memory block is completed, the key buffer of a keyboard controller is checked to confirm the existence of any key input. When a key input is detected, the power saving process is suspended, and the system is restored to the previous operating state.
