Embodiment Construction

[0013] Such as figure 1 Shown is a hardware architecture diagram of a preferred embodiment of the method for obtaining synchronization of power state of the present invention. The hardware architecture diagram includes a computer 1. In this embodiment, the computer 1 may be a desktop computer, a notebook, a server, etc. The computer 1 includes a power supply system 10, the power supply system 10 is connected to a basic input output system (Basic Input Output System, BIOS) 11 through a signal line, and the BIOS 11 is connected to a baseboard management controller (BMC) 12. The power system 10 includes an advanced configuration and power interface (ACPI) 100.

[0014] The BIOS 11 or BMC 12 sends a command for acquiring the power state to the ACPI 10, and the ACPI 10 feeds back the power state to the BIOS 11 or BMC 12. The computer 1 further includes an operating system 13, and the operating system 13 includes a system management software (SMS) 130. The SMS 130 provides an interfa...

Abstract

The invention relates to a synchronous obtaining method of power state, which is applied in a power system of a computer, wherein the power system comprises an ACPI (Advanced Configuration and Power Interface) and is connected to a BIOS (Basic Input Output System); the BIOS is connected to a baseplate managing controller; the method comprises the following steps of: running an operation system of the computer after the power system is started; when the power state of the ACPI is detected by the BIOS to be changed, entering into a system managing terminal and processing the process by means of the operation system; and sending a demand to the baseplate managing controller and informing the baseplate managing controller of the power state of the ACPI by means of the BIOS. By utilizing the method provided by the invention, a user can synchronously obtain the power state through the BIOS and the baseplate managing controller.

Description

Technical field [0001] The invention relates to a power management method, in particular to a method for synchronously acquiring a power state. Background technique [0002] Advanced Configuration and Power Interface (ACPI) defines a new type of working interface between the operating system, BIOS and system hardware. These new interfaces include mechanisms that allow the operating system to control power management and device configuration. ACPI usually includes six states: S0 ~ S5, each state has important reference significance for users or system administrators. The Intelligent Platform Management Interface (IPMI) specification provides standard commands for obtaining ACPI status, but the traditional way to obtain ACPI status is to report the three general purpose input / output (General Purpose Input Output) , GPIO) signal line is connected to a baseboard management controller (baseboard management controller, BMC). Each GPIO signal can represent two states of power, and th...
