A computer power supply control method and device

Abstract

The invention provides a computer power supply control method and device. The method includes: acquiring power supply information of the computer in a normal working state, the power supply information including battery power supply and external power supply; when the power supply information is battery power supply, acquiring the discharge current or battery temperature of the battery power supply, and According to the discharge current or battery temperature, the central control unit is controlled to operate at the first operating frequency or the second operating frequency; when the power supply information is an external power supply, the central control unit is controlled to operate at the first operating frequency. The present invention can adjust the operating frequency of the central control unit according to the discharge current of the battery power supply or the battery temperature, so that the computer system can run stably for a long time under special circumstances, and avoid the sudden power failure of the computer system causing important data lost or damaged.

Description

technical field [0001] The invention relates to the technical field of computer control, in particular to a computer power supply control method and device. Background technique [0002] With the miniaturization and portability of computers, more and more computers are used in various complex outdoor environments. Therefore, it is very important to ensure that the computer can maintain stable operation under the conditions of indoor power supply and outdoor battery power supply. [0003] When the computer works with only the battery, the greater the CPU load, the higher the battery discharge current and the higher the battery temperature. In order to protect the service life of the battery, at present, when the battery is increased to a certain temperature, It will stop power supply or turn off the device with heavy load. It usually causes the computer not to work stably, and causes important data to be lost or damaged. [0004] In the prior art, in order to reduce the CPU...

AI Technical Summary

Problems solved by technology

It usually causes the computer not to work stably, and causes important data to be lost or damaged.

[0004] In the prior art, in order to reduce the CPU load, the main frequency of the CPU is directly reduced in the power options to reduce the power consumption and heat generation of the CPU. In this way, the processing speed and performance of the computer are reduced when the computer is powered by a stable power supply.
