Abstract

The invention provides a power supply control method and system of a server system, a medium and equipment. The method comprises the following steps: setting an original state recovery strategy in a system management module of the server system; in response to the power failure of the AC power supply in the operation process of the server system, sending a power loss signal to the logic processing module and the system management module through the system power supply module; in response to the power loss signal received by the logic processing module, judging the level state of the received power supply state signal from the central processing unit, identifying the on-off state of the server system, and storing the identification result; in response to the power loss signal received by the system management module, sending an access signal to the logic processing module, and obtaining and storing an identification result; reading an identification result through the system management module in response to power restoration of the AC power supply; and using the system management module to control startup or shutdown based on the identification result. The invention realizes simple and reliable control of a power supply of a server system.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to a power control method, system, medium and equipment of a server system. Background technique [0002] On general-purpose X86-based computers, there is a function called Restore on AC Power loss, which is generally controlled by ME in the PCH, so that the system can automatically restore the state of the computer when the AC (alternating current) power supply is disconnected and restored. Usually this function can be set under the BIOS. If you select Last State in the BIOS, it means that after AC FAIL occurs, that is, after the AC power supply is disconnected and restored again, the system judges which state to restore to according to the state before the last power failure. [0003] In the existing technical solutions, there are two commonly used processing methods: [0004] 1. Perform AC POWER LOSS related settings in the BIOS, and then the related settings are stored ...
