Abstract
An electronic device is provided. The electronic device includes a plurality of expansion connector modules, a power supply path switch circuit, a system load and a controller. The power supply path switch circuit includes a plurality of input ends connected to output ends of expansion connector modules respectively. The system load is coupled to the power supply path switch circuit. The controller is coupled to the expansion connector module and the power supply path switch circuit. The controller determines whether a first power supply source is coupled to one of the expansion connector modules through the expansion connector modules. When the first power supply source is connected to the one of the expansion connector modules, the controller detects the power of the first power supply source via the expansion connector module connected to the first power supply source. Then, the controller adjusts a power supply direction between the expansion connector module connected to the first power supply source and the system load according to the power of the first power supply source.
