Method for fast resuming computer system and computer system

Abstract

A method for fast resuming a computer system from a shutdown state is provided. The computer system comprises a basic input output system (BIOS), a system memory and a storage device storing a system memory data of the system memory and a used system memory block address table before the computer system enters the shutdown state. The method comprises receiving a starting signal for power supplying the computer system and starting the storage device. A fast boot built-in program of the BIOS is started and, according to the used system memory block address table, the fast boot built-in program sequentially reads the stored system memory data from the storage device and writes the read system memory data into the system memory with a use of an optimized read-and-write block size as a read-and-write unit. The computer system enters a suspended state and is resumed from the suspended state.

Description

technical field [0001] The present invention relates to an operating method and a computer system, and in particular to a method for quickly waking up the computer system and the computer system. Background technique [0002] In the Advanced Configuration and Power Interface (ACPI) standard, in addition to the working state (that is, the S0 state), the state of the computer system also includes a sleep state (sleeping mode) that consumes less power. . According to different power consumption and recovery speed, the sleep state can be divided into several levels such as S1 state, S3 state, S4 state, and S5 state. In S1 (power on suspend) state, the computer system only turns off the screen, so it can quickly return to the working state. And in the standby state S3 called memory dormancy (suspend to ram), except the memory and its controller need power to keep data, other devices all stop power supply. The S4 (suspend to disk) state is to store the data in the memory on the...

Execution of the above actions will cause the startup time of the computer system to become very lengthy

[0004] In addition, when the computer system enters the S3 state, it must continue to supply power to the memory to save the memory content. Otherwise, once the power supply to the memory is stopped, the memory content will be lost and the computer system will not be able to return to the operating state before entering the S3 state.

As a result, when the computer system is in the S3 state for a long time, the battery must continue to supply power, so it is easy to reduce the service life of the battery
