Abstract

Method and apparatus for enabling a suspend-to-disk (S2D) state to be associated with a hard disk to which the operations of a personal computer (PC) have been suspended, rather than with the PC itself. In a preferred embodiment, responsive to initiation of an S2D operation, a partition table stored in a partition sector of the hard disk is copied to a known address within an S2D partition of the hard disk and the copy of the partition table stored in the partition sector is altered such that the S2D partition, rather than a native operating system (OS) partition, is designated as the active partition. The S2D operations continue in a conventional manner, with the state of the PC being saved to the hard disk, at which point the PC is powered off. When the PC is subsequently powered back on, the PC boots up from the S2D partition. A resume-from-disk (RFD) program writes the copy of the partition table previously stored in the S2D partition back to the partition sector and then restores the state of the PC.
