发明名称 Method and system for automatically returning an information processing apparatus to a state before power outage
摘要 An information processing apparatus includes a first control unit configured to control a processing unit; a first power supply that supplies power to the first control unit; a switching unit configured to switch on or off the first power supply; a second control unit configured to operate according to a setting and control the switching unit; a second power supply that supplies power to the second control unit; and a setting change unit configured to perform the setting of the second control unit so that the switching unit switches off the first power supply when a voltage of the second power supply is lower than a preset voltage, and perform the setting of the second control unit so that the switching unit switches on the first power supply when the voltage of the second power supply is equal to or higher than the preset voltage.
