ABSTRACT:
Electric apparatus, computer apparatus, controller, and battery switching method and program is provided to prevent a system shutdown caused by a reduction of electric power from a battery. A computer apparatus is constructed to be able to accept and be powered by a rechargeable main battery and a rechargeable sub-battery. An embedded controller in the computer apparatus monitors a remaining capacity at a pre-specified temperature of the sub-battery under discharge by receiving information from CPU. When the monitored temperature exceeds a predetermined temperature and when the monitored remaining capacity becomes less than a predetermined capacity, the embedded controller receives electric power from the main battery by switching the power supply circuit to provide power from the main battery instead of the sub-battery.
