According to one embodiment, a power supply circuit normally generates a plurality of power supply voltages, which are to be used in an information processing apparatus, from a direct-current power supply voltage generated from an alternating-current power supply by an alternating-current adapter and generates the power supply voltages from a battery power supply when the alternating-current power supply is shut off. The power supply voltages include a specific power supply voltage to be used in a network controller. A power supply controller controls the power supply circuit to inhibit the specific power supply voltage from being applied to the network controller if the alternating-current power supply is shut off while a system operating state of the information processing apparatus is one of a sleep state and a shutdown state.
