ELECTRONIC APPARATUS, POWER SUPPLY CONTROL METHOD, AND POWER SUPPLY CONTROL PROGRAM

PROBLEM TO BE SOLVED: To provide an electronic apparatus or the like, which allows the electronic apparatus to be immediately activated even in the case that a battery to supply power to the electronic apparatus is in a completely discharged state.SOLUTION: An electronic apparatus 1 which is supplied with power from an external power source 2 and a battery BAT comprises: an external supply current acquisition part 102 which acquires information on external supply current supplied from the external supply source 2 having a current capacity smaller than the maximum load current of the electronic apparatus 1; a battery voltage detecting part 103 which detects the voltage of the battery BAT; subfunction executing parts 110 to 113 which execute subfunctions of the electronic apparatus 1; a system control part 105 which determines whether the battery BAT is in a completely discharged state or not on the basis of the detected voltage of the battery BAT; and switching control parts 106 to 109 which restrict the behaviors of the subfunction executing parts 110 to 113 such that the load current of the electronic apparatus 1 is smaller than the external supply current.
