ABSTRACT:
A computer system is provided with both an auto power off mode and a resume mode. In the computer system, the motor off command for an HDD is kept effective from the time when the system is turned on to the time when the HDD is accessed. During the interval, therefore, no power is supplied to the HDD. When the HDD has just been accessed, the motor off command is made ineffective, to thereby supply power to the HDD. When the power supply to the HDD is started, with the system in the resume mode, the CPU permits data processing to be performed from the state immediately before the power supply is stopped.
