  • ELECTRONIC DEVICE AND POWER CONTROL METHOD THEREOF
    Publication number: 20140118367
    Abstract: The electronic device includes a central processing unit and a graphics processing unit. The graphics processing unit is coupled to the central processing unit. The graphics processing unit includes multiple output interfaces. A power is supplied to the graphics processing unit and the output interfaces through the coupling between the output interfaces and an expanded device. Under the condition that the output interfaces are not coupled to the expanded device, the power is stopped supplying to the graphics processing unit and the output interfaces when the electronic device is under a first power supply mode. Moreover, under the condition that the output interfaces are not coupled to the expanded device, the power is supplied to the graphics processing unit and is stopped supplying to the output interfaces when the electronic device is under a second power supply mode.
