Abstract

A reset system of system power supply state after power supply of computer platform is restored comprises response module of power supply restoration event, pressed down event response module of power supply key and response module of dormant mode activation event. The method for resetting system power supply state at time when power supply of computer platform is restored is also disclosed.

Description

technical field [0001] The present invention relates to a computer information technology, in particular to a method and system for resetting the system power state after the computer platform restores the power supply, which is applied to a computer platform, such as a network server, a desktop personal computer, a notebook computer, etc. etc., provide a system power state reset processing function for the computer platform after the power supply is restored, and reset the system power state (System Power State) Reset to the state at the time of the previous power loss condition. Background technique [0002] ACPI (Advanced Configuration and Power Interface) is a high-performance computer status and power management technology, which has been widely used in various computer platforms, including network servers, desktop personal computers, notebook computers, etc. These computer platforms provide a high-performance state and power management function, and the application of...
