ABSTRACT:
According to one embodiment, an information processing apparatus includes a housing, a power supply incorporated in the housing, a conversion unit which converts a voltage supplied from the power supply, a detection unit which detects a voltage supplied from the power supply, and a control unit which, when the voltage detected by the detection unit has become less than or equal to a specific threshold value, controls the power supply so as to lower not only a voltage output from the conversion unit by a specific percentage but also a voltage supplied to the detection unit by a specific percentage.
