Abstract:
1. A computer, comprising: a system part to process data; a battery to supply power to the system part; and a control system to determine a residual amount of the battery, to calculate a decreased residual amount of the battery based on a difference between the determined residual amount and a previous residual amount, and to control the power supply to the system part based on comparing the calculated decreased residual amount to a nonzero predetermined value and comparing the residual amount to a predetermined critical residual amount, wherein: if it is determined that the decreased residual amount of the battery is lower than the predetermined value and that the residual amount of the battery is lower than the predetermined critical residual amount, the control system controls to cut off the power supply to the system part; and if it is determined that the decreased residual amount of the battery is higher than the predetermined value, the control system controls to maintain the power supply to the system part.
