ABSTRACT:
In a computer system equipped with a hibernation type resume function including standby control functions, a power supply controller detects whether AC power or battery power is used as power for the system. When AC power is supplied, power is kept supplied to a memory even when a power switch is set off. When the power switch is set on later, an AC standby control function to set the system back to the operational state is executed based on the memory contents.
