Abstract:
A portable terminal adapted to be coupled to a battery for providing power thereto, said portable terminal comprising:a plurality of peripheral circuits;a control means for individually controlling the supply of power to said peripheral circuit and issuing a remaining battery capacity detection request in response to an external drive request;a voltage detection means for detecting a voltage of said battery, including means for determining if said remaining battery capacity detection request has been issued, said voltage detection means only detecting a voltage of said battery in response to said remaining battery capacity detection request supplied from said control means in response to said drive request; anda judging means which judges the remaining capacity of said battery based on said voltage detected by said voltage detection means, and which further makes a judgment as to whether or not there is sufficient remaining capacity of said battery to satisfy said drive request,wherein when a judgment result of said judging means is that there is sufficient remaining capacity to satisfy said drive request, said control means causes said battery to supply power in response to said drive request.
