Abstract

The invention discloses a power supply method and first electronic equipment. The power supply method comprises the following steps: obtaining the power supply priority of a first input interface of the first electronic equipment as a first priority, and obtaining the power supply priority of a second input interface as a second priority; when a detection result shows that the second electronic equipment is connected to the first electronic equipment through the first input interface, controlling a first power supply access which at least comprises the second electronic equipment and the first input interface to be under a condition state so as to supply power to the first electronic equipment; and when a detection result shows that third electronic equipment is connected to the first electronic equipment through the second input interface and the second priority is higher than the first priority, controlling the first power supply access to be regulated to a disconnection state from the conduction state at a first moment, and controlling a second power supply access which at least comprises the third electronic equipment and the second input interface to be under the conduction state at the first moment so as to supply power to the first electronic equipment.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a power supply method and a first electronic device. Background technique [0002] With the development of science and technology, electronic devices such as notebook computers and tablet computers are becoming thinner and lighter and more portable. However, it also brings some problems, among which, the most typical problem is: the electronic equipment has few built-in ports, which cannot meet the user's functional requirements for the electronic equipment. [0003] In the prior art, in order to solve the above-mentioned problem of few self-contained ports, a docking station has appeared. The main function of the docking station is to expand the functions of electronic equipment, such as drivers, large-screen displays, keyboards, printers, Various external devices such as scanners. [0004] In the prior art, in addition to expanding the functions of the electronic ...
