Abstract
A portable electronic device comprises a battery, a display, a switch and a processor. The battery is for supplying operating power. The switch includes a magnetic element and a sensor configured for detecting the magnetic flux of the magnetic element. The sensor has a first predetermined value for turning on the switch. The switch is turning on in response to the magnetic flux of the magnetic element detected by the sensor being equal to the first predetermined value of the sensor. The processor is coupled to the switch, the battery and the display. The processor responsive to turning on of the switch for controlling supply of operating power from the battery to the display. The processor maintains supply of operating power from the battery to the display in response to turning on of the switch.
Claims18
