Abstract:
1. A power control apparatus of a terminal device, comprising: a power controller for controlling power supplied from a battery to the terminal device, wherein the power controller is configured to determine whether to apply power to a system when the system is shut down by a cutoff mode, the power controller determining whether to selectively apply power according to a state of a flag and determining an amount of power to be applied based on a determination of a first cutoff voltage or a second cutoff voltage; and a memory for storing first and second cutoff voltage values for shutting down the system upon determining that a voltage of the battery is lower than the first cutoff voltage or the second cutoff voltage, wherein the power controller sets the flag when the system is shut down by the cutoff mode, wherein if the flag has not been set when the system is driven, the power controller determines whether to apply power to the system based on the first cutoff voltage and if the flag has been set when the system is driven, the power controller determines whether to apply power to the system based on the second cutoff voltage.
