Abstract: An on-vehicle computer includes a hardware timer. The hardware timer is started when a vehicle accessory switch changes to its OFF position. A suspending request is transmitted from a BIOS to an application program and a BIOS timer is started when the vehicle accessory switch changes to its OFF position. A suspending permission answer is returned from the application program to the BIOS and an application program timer is started in response to the suspending request. A first turn-OFF command is generated when an elapsed time measured by the application program timer reaches a first predetermined time interval (T2). The BIOS is enabled to generate a suspending command in response to the suspending permission answer. A second turn-OFF command is generated in cases where the suspending permission answer continuously fails to be returned to the BIOS until an elapsed time measured by the BIOS timer reaches a second predetermined time interval (T1).
