In a battery-driven computer system, a flip-flop circuit selects one of two switches for switching a power supply to the computer system in accordance with the terminal voltages of batteries detected by detecting circuits. When the first switch is switched on, the first battery coupled to the first switch supplies its power to the computer system. In this case, the second switch is switched off and the power from the second battery coupled to the second switch is not supplied to the computer system. When the terminal voltage of the first battgnal representing the power condition of the batteries.
