Abstract

Abstract In a power supply control apparatus capable of connecting an AC adapter, it is determined by a controller whether or not the AC adapter is connected. When a battery is set in the apparatus, it is determined whether the battery is in a low battery state. When the AC adapter is connected and the set battery is in a low battery state, charge operation for the battery is started. During charging, a charged state is monitored on the basis of the current value detected by a current detector and a charge time measured by a timer. When the charge amount exceeds a predetermined amount, or the charge time exceeds a predetermined charge time, the charge operation is completed and the battery is used as a power supply.
