Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0048] The present invention proposes a "peripheral resume on demand mechanism" in the system resume procedure, and only resumes (resume) the immediately necessary peripheral devices, and allows the non-immediately necessary peripheral devices Remain in a suspended state, or a fakeresumed state that pretends to have been successfully restored, and bypasses the system recovery procedure. After the system recovery process is completed, when the application program puts forward the use demand for the peripheral device in the suspended state or the pseudo-recovery state, it will perform an action of restoring the peripheral device in the suspended state or the pseudo-recovery state. In this way, the system recovery program ca...

Abstract

A system suspending method, a system resuming method and a computer system using the same are provided. The system resuming method of the computer system is applied for resuming the computer system to be a normal status (S0 status) from a suspend-to-ram status (S3 status) or a suspend-to-disk status (S4 status). The computer system includes a plurality of peripheral devices and a central processing unit. The peripheral devices are classified into a first group and a second group. The system resuming method includes the following steps. The central processing unit is powered on. Then, the peripheral devices belonging in the first group are resumed. Next, the computer system is thawed.

Description

technical field [0001] The invention relates to a system suspension method, a system recovery method and a computer system using the same. Background technique [0002] The method of using the hibernation technology (suspend to disk) to achieve fast booting has been widely adopted. In the sleep mode ( S4 ), the information of the memory is written to the external storage medium, and the operation of all peripheral devices is stopped. [0003] In the system suspend procedure of general hibernation technology, the content of the memory will be made into a hibernate file and written to an external storage medium. [0004] In the system resume procedure of the hibernation technology, all peripheral devices are initialized, and the hibernation file is loaded to restore all peripheral devices. However, in such a system recovery process, it takes a considerable amount of time to initialize and recover all peripheral devices, which creates a bottleneck in the execution speed of fa...
