Abstract

The invention provides a power supply method, a power supply system and an electronic terminal. The power supply method comprises the steps of detecting a current voltage valve of a first voltage when a first power supply is used for providing power for an electronic terminal system and a central processor, judging whether the current voltage value of the first voltage is within the range of the first voltage, and controlling a second power supply to provide a third voltage for the electronic terminal system and controlling the second power supply to provide a fourth voltage for the central processor when the current voltage value of the first voltage is within the range of the first voltage.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a power supply method, system and electronic terminal. Background technique [0002] With the increasing popularity of electronic devices, more and more users use commercial desktop computers or home desktop computers or other electronic terminals. Regions or emergencies (such as earthquakes), etc., will cause sudden power failure or interruption of the AC power input, making the voltage and current output by the power supply unit abnormal. When the electronic terminal suddenly has no power supply, resulting in data loss, it will give losses to users. [0003] In order to solve the aforementioned problems, the solution in the prior art is to adopt UPS (uninterruptible power system; uninterruptible power supply), which is an important external device capable of providing uninterruptible power supply. However, in the process of realizing the present invention, the inven...
