Abstract
An information processing apparatus including a first bus connected a first bus device, a second bus connected to a second bus device, and a bus bridge connecting the first bus and the second bus. A power control unit supplies electric power to the first bus device and the bus bridge when the information processing apparatus is in an operative state, and stops power supply when the information processing apparatus is in a power saving state. A transmission control unit controls transmission of a recovery signal which is entered from the second bus device and transmitted to the power control unit to return the information processing apparatus from the power saving state to the operative state, when the information processing apparatus is in the power saving state. The power control unit resumes the power supply to the first bus device and the bus bridge in response to the recovery signal.
