Abstract

PURPOSE:To obtain a computer system whose power consumption is small, by turning on a power source of a hard disk device, only when the hard disk device is required. CONSTITUTION:A fundamental input/output system 22 decides ON or OFF of a power source of a hard disk device 24 and in case of ON, when the hard disk device 24 is in a non-operating state, the power source of the hard disk device 24 is turned OFF. Subsequently, when an application soft 21 outputs an input/output request (read, write, etc.) of the hard disk device 24 to the fundamental input/output system 22, the fundamental input/output system 22 decides ON or OFF of the power source of the hard disk device 24. In case of OFF, the power source of the hard disk device 24 is turned ON, and there after, the initialization of HDC and HDD is executed, and thereafter, an input/ output processing of the hard disk device 24 is executed. In such a way, the power consumption of the computer system can be reduced.
