Abstract: According to one embodiment, an information processing apparatus includes an optical disc drive, a data processing module which executes data processing using the optical disc drive, and a power supply management module which manages supply of power to the optical disc drive. The data processing module interrogates the power supply management module about the optical disc drive at the time of activation, and waits until an operating system recognizes the optical disc drive when an instruction is received from the power supply management module in response to an interrogation. The instruction instructs to wait until the operating system recognizes the optical disc drive. The power supply management module shifts the optical disc drive to a power supply on state and returns the instruction to the data processing module, if the optical disc drive is in a power supply off state when the interrogation is received.
