Problems solved by technology

[0003] Due to the stability requirements of its operation, computer systems such as servers are usually equipped with a backup power supply. When the external power supply is cut off, the backup power supply supplies power to the server in time, and the server immediately enters the S3 or S5 working state, and then passes through the BIOS system in the computer system. (Basic input and output system) to restore the computer system to the S1 working state, but because the BIOS system is powered by the battery, when the battery power is exhausted, it cannot restore the computer system to the S1 working state in time, on the other hand, due to the BIOS system settings can easily be modified, thereby affecting the reliability of its power supply control of the backup power supply

Abstract

The invention discloses a computer system backup power supply circuit which comprises a backup power supply, a power supply chip arranged in a computer system, a control unit and a delay trigger unit, wherein the power supply chip is connected to the backup power supply; the control unit is connected to the power supply chip; the delay trigger unit is connected to the control unit; and the control unit is used for controlling the power supply chip to switch the working state of the computer system after the timing operation of the delay trigger unit is over. The invention further discloses a computer system backup power supply method.

Description

technical field [0001] The invention relates to a power supply circuit and method, in particular to a power supply circuit and method for a backup power supply of a computer system. Background technique [0002] According to the ACPI (Advanced Configuration and Power Interface, advanced configuration and power interface) specification, the computer power management system can divide the working state of the computer into five working states from S0 to S5, and the meanings they represent are: S0: the computer is working normally , all hardware devices are turned on or working normally; S1: also known as POS (Power on Suspend), the CPU stops working, and other hardware devices still work normally; S2: the CPU is turned off, but the rest of the hardware devices are still running ;S3: usually called STR (Suspend to RAM, suspend to memory), write the running data into memory and then turn off the hard disk; S4: also called STD (Suspend to Disk, suspend to hard disk), write memory...
