Information processing apparatus

An information processing apparatus comprising:

• a connector configured to detachably connect a cable comprising a first signal line for transmitting video signals and audio signals, a second signal line for receiving and transmitting various commands for operation control, the cable comprising a third signal line for retrieving identification information of a connection destination for performing operation control based on the various commands, and a fourth signal line for detecting a state of electrical connection with a connection destination;
• a graphics controller configured to control output of video signals and audio signals from the first signal line, the graphics controller comprising a first retrieving module configured to retrieve identification information of the connection destination via the third signal line when the state of electrical connection with a connection destination is detected by the fourth signal line;
• and
• a power supply control module configured to control power supply for members comprising the graphics controller, the power supply control module comprising a management controller configured to receive and to transmit the various commands via the second signal line, the management controller comprising a second retrieving module configured to retrieve identification information of the connection destination via the third signal line when the state of electrical connection with the connection destination is detected by the fourth signal line,
• wherein the management controller of the power supply control module is configured to deactivate the second retrieving module when the state of electrical connection with the connection destination is detected by the fourth signal line during a power-on state.
