Abstract
A computer implemented method resumes a computer from a power-saving state in a short time. Prior to shifting to a power-saving state, a drive sets a status flag indicating a loading state of a disk at a flash memory. For resumption from the power-saving state, the BIOS requests a ready notification from the drive. When it is determined that the status flag indicates not-loading of a disk, the drive skips the detection processing of the disk including initialization of a read/write circuit and a servo mechanism such as a spindle motor and sends a ready notification indicating not-loading of the disk to the BIOS. Receiving the ready notification, the BIOS can continue the resume processing.
