Patent ID: 8782445

Claim:
An information processing apparatus comprising: an optical disc apparatus comprising a tray configured to receive an optical disc; modules other than the optical disc apparatus; a power-supply controller configured to control a supply of electric power from a power supply to the optical disc apparatus and each of the modules; and a receiver configured to receive a command to eject the tray in the optical disc apparatus, and configured to transmit information about the command to the power-supply controller, wherein, when the supply of electric power to each of the modules is stopped, the power-supply controller is configured to continue the supply of electric power to the optical disc apparatus during a time period, wherein, when the power-supply controller receives the information about the command within the time period, the power-supply controller is configured to eject the tray and to stop the supply of electric power to the optical disc apparatus, wherein the power-supply controller is configured to determine whether the power supply is connected to an external power source, and wherein, when the power-supply controller determines that the power supply module is not connected to the external power source, the power-supply controller is configured to stop the supply of electric power to the optical disc apparatus.
