To execute a series of operations for hibernation and wake-up at a high speed in a system in which an address for saving the content of the main memory serves as a hibernation file managed by the OS file system , when the information processing system enters hibernation mode, the system accesses an area on an external storage device where file allocation information managed by the OS file system thereby obtaining allocation information of the hibernation file and input the information into a buffer. The system uses allocation information in the buffer to save the content of the main memory and VRAM as well as allocation information into the hibernation file. In addition, the address information at the location on the external storage device where allocation information is saved is stored in a predetermined control information area. When the system is woken up, allocation information already residing in the hibernation file is used to restore the main memory and VRAM from the hibernation file.
