Information processing apparatus and power supply control method

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, and
• 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.
