An electronic apparatus includes a power receiving unit that receives power from an external apparatus connected to an interface unit, a first generating unit that generates a first control signal, a second generating unit that generates a second control signal, a third generating unit that generates a third control signal, a fourth generating unit that generates a fourth control signal using the first to third control signals, a charge control unit that charges a battery with power received from the external apparatus when the fourth control signal is in a low state, and that stops charging the battery when the fourth control signal is in a high state, and a power supply unit that starts supplying power from the battery to the second generating unit when the fourth control signal is changed into a high state.
