ABSTRACT:
An apparatus driven by an output voltage of a battery when the power is ON includes a voltage detection circuit for detecting the output voltage of the battery, a judging circuit for judging whether or not a remaining capacity of the battery is greater than a predetermined value based on an output detection signal of the voltage detection circuit, and a control circuit for carrying out a resume process only if the judging circuit judges that the remaining capacity of the battery is greater than the predetermined value when the power is turned ON. The resume process returns a state of the battery powered unit to a state at a time when the power was previously turned OFF.
