According to one embodiment, an information processing apparatus includes a connector, a graphics controller, a management controller, and a power supply control module. The graphics controller controls output of video signals and audio signals from the connector. The management controller inputs/outputs the various commands via the connector. The power supply control module supplies power for operation to both of the graphics controller and the management controller during a power-off state, and supplies power for operation only to the management controller in a power-on state. Both of the graphics controller and the management controller include a function of acquiring identification information of the connection destination by means of the signal line. And, the management controller deactivates the function of acquiring identification information of the connection destination by means of the signal line during a power-on state.
