Abstract

The invention provides a computer power supply control method and device. The method comprises the following steps of: acquiring power supply information of a computer in a normal working state, wherein the power supply information comprises battery power supply and external power supply; Obtaining a discharge current or a battery temperature of the battery power supply when the power supply information is supplied to the battery power supply, and controlling the central control unit to operate at a first working frequency or a second working frequency according to the discharge current or thebattery temperature; When the power supply information is supplied to an external power supply, controlling the central control unit to operate at a first operating frequency. The invention can adjust the working 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 be operated stably for along time under special circumstances, and the important data loss or damage caused by the sudden power failure of the computer system can be avoided.

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...
