Abstract
An information processing apparatus driven by an AC power supply or a rechargeable battery has a charge directing unit which initiates charging of the battery from the AC power supply, provided that the remaining amount of power of the battery is lower than a predetermined charge-start-criteria level and that the information processing apparatus is driven by the AC power supply. Also included is a drive history storage which stores a drive history including information indicating which of the AC power supply and the battery was driving the information processing apparatus in each time period in the past. A recharge-start-criteria-level-setting unit sets the charge-start-criteria level on the basis of the drive history.
