Abstract
A power control method of an electronic device is provided. The method includes receiving a power-on event in a power-off state of the electronic device and determining whether the received power-on event is a real time clock (RTC) interrupt. The method further includes determining, if the power-on event is the RTC interrupt, whether the power-off state is caused by an abnormal power-off, and performing, if the power-off state is caused by the abnormal power-off, a booting procedure.
Claims15
A power control method of an electronic device, the method comprising:
- receiving a power-on event in a power-off state of the electronic device;
- determining whether the received power-on event is a real time clock (RTC) interrupt;
- determining, if the power-on event is the RTC interrupt, whether the power-off state is caused by an abnormal power-off based on a flag for ascertaining the abnormal power-off;
- and
- performing, if the power-off state is caused by the abnormal power-off, a booting procedure,
- wherein the flag is set to an off-state when the electronic device performs a booting procedure.
