The invention discloses a system power state reset processing method and system after a computer platform resumes power supply, which is mounted on a computer platform to provide the computer platform with a system power state reset processing function after power restoration; the system at least includes: power supply restoration An event response module, a power button pressing event response module, and a sleep mode activation event response module. After the computer platform restores the power supply, the system power supply state reset processing method and system of the present invention set the state flag (AFTER_G3) and the status flag (AFTER_G3) and The associated ACPI system power state (S0, S1, S4, S5). The method and system for resetting the system power state after the computer platform restores the power supply of the present invention are applicable to various computer platforms that are not equipped with BMC and SIO, and thus have wider cross-platform effects in application.
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...
