  • Publication number: 20130069436
    Abstract: An apparatus configured to control power off in an apparatus includes a power unit, a battery detachment detector, an input unit, and a controller. The power unit supplies power from at least one of a battery and an auxiliary power unit. When detecting that the battery is separated from the power unit, the battery detachment detector outputs a battery separation signal to the input unit using power from the auxiliary power unit. When receiving the battery separation signal from the battery detachment detector, the input unit generates a power off event using power from the auxiliary power unit. When the power off event occurs from the input unit, the controller performs a power off procedure using power from the auxiliary power unit.
