ABSTRACT:
To provide a power control apparatus for reducing power, wherein the user can specify a time interval to stop driving a system, such as a computer system, there are provided a system-state detecting unit for detecting the drive state of the system, measuring unit for measuring a drive-stop designation time period Toff from the time when the system finishes processing to the time when the user designates drive-stop for the system, and for measuring a drive-start designation time period Tcont from the time when the system finishes processing to the time when the user designates drive-start for the system after the system is automatically stopped, a power-off-time determining unit for determining the automatic-drive-stop time period from the time when the system finishes processing to the time when the drive automatically stopped, according to the drive-stop designation time period, a time reporting unit for measuring the idling time from the time when the system finishes processing to the time when processing is started again and for reporting that the idling time has exceeded the automatic-drive-stop time period, and a system control unit for stopping the driving of the system according to the report.
