ABSTRACT:
A power control method for a portable electronic device. The portable electronic device comprises a power supply unit and a volatile memory for storing data when the power supply unit supplies power thereto. First, the portable electronic device is set to enter a deep sleep mode. Then, data accessed from the volatile memory is transferred to a non-volatile memory. Finally, except for maintaining sufficient power to restore the device, the power supply unit is turned off.
