A power supply control device, applied for an electronic device is disclosed. The electronic device includes a case, wherein a user holds the case to operate the electronic device. The power supply control device includes a sensing module, including a first sensing component for sensing whether the user is touching a first sensing area of the case to generate a first determination signal; and a second sensing component for sensing whether the user is touching a second sensing area of the case to generate a second determination signal; and a power supply module, including a first relay, for connecting or disconnecting a system power end of the electronic device from a power supply terminal according to the first determination signal; and a second relay, for connecting or disconnecting a system ground end of the electronic device from a ground terminal according to the second determination signal.

Power supply control device and operating method using the same

An electronic device and a power supply method thereof are provided. The electronic device includes a control circuit, a detachable power supply device, and an auxiliary power supply device. The control circuit is coupled to a power supply terminal coupled to a system load. When the detachable power supply device is assembled to the electronic device, the detachable power supply device is coupled to the control circuit and supplies power to the system load. The auxiliary power supply device is coupled to the control circuit. When the electronic device is not turned on and the detachable power supply is removed from the electronic device, the electronic device is not turned on by the auxiliary power supply device. When the electronic device is turned on and the detachable power supply is removed from the electronic device, power is continuously supplied to the system load by the auxiliary power supply device.
