ABSTRACT:
A computer system has volatile random access memory ("RAM") and nonvolatile auxiliary storage, a virtual memory operating system with some pages of virtual memory resident in RAM and other pages resident in a paging space in auxiliary storage. A time varying operating state for the computer is definable by reference to contents of the memory. A space in auxiliary storage (a "hibernation space") is allocated for storing a portion of RAM as a hibernation image. A first group of the RAM-resident virtual memory pages is stored in the paging space. A second group of the RAM-resident virtual memory pages is stored in the hibernation space. A hibernation state is entered where the computer system is powered off with the system at a certain operating state. The computer system is returned to operation at the certain operating state, which includes powering on the computer system and reading the second group of pages into the RAM.
