Abstract

The invention discloses a power supply method, a power supply system and electronic equipment and aims to solve the technical problem that the electronic equipment in the prior art is complicated in structure and realize the technical effects of simplifying the internal structure of the electronic equipment and lowering the manufacturing cost of the electronic equipment. The method comprises the following steps of when a power supply battery in the electronic equipment is in a first power supply state for supplying power to a first working circuit comprising a real-time clock (RTC) and a second working circuit, detecting and acquiring the current voltage of the power supply battery as a first voltage, wherein the power supply battery is connected with the first working circuit and the second working circuit by a voltage stabilizer; the second working circuit is a booting circuit comprising a power switch; judging whether the first voltage is smaller than a preset voltage to obtain a first judgment result; if the judgment result is yes, controlling the power supply battery to be switched from the first power supply state into a second power supply state for supplying power to the first working circuit.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power supply method, a power supply system and electronic equipment. Background technique [0002] With the rapid development of science and technology and the increasingly fierce market competition, the performance and appearance of electronic equipment have been greatly improved. Among them, notebook computers are being loved by more and more people because of their small size, light weight, easy portability, and strong entertainment. , become an indispensable part of learning and life. There are more and more things that users can do with electronic devices, such as: users can communicate, watch videos, play games, etc. through tablet computers with communication functions. [0003] At present, in order to ensure the system time of electronic equipment, it is often necessary to set an RTC battery for the RTC (Real-Time Clock, real-time clock) circuit in electronic equip...
