Problems solved by technology

[0007] To sum up, although the existing S3 method can realize the fast power on and off of the PC, the memory in the S3 state needs power to maintain work. Once the power is turned off, it is easy to cause data loss in the memory; although the existing S4 method does not There will be data loss, but it still takes a long time to switch on and off using the S4 method

Embodiment Construction

[0044] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0045] The present invention applies the nonvolatile memory (NVRAM, Nonvolatile Random Access Memory) to the PC, and is used for valid data in the internal memory of the PC at the time of shutting down, the register state value of the chipset controller, and the register state of the I / O interface. value is stored. When the PC is shutting down, the effective data in the memory at the time of shutting down, the register status value of the chipset controller and the register status value of the I / O interface are quickly written into NVRAM to realize fast shutdown; Quickly read the effective data in the memory at the time of shutdown, the register status value of the chipset controller and the register status value of the I / O interface, and realize the quick recovery of the operating system. In the present invention, no...

Abstract

The invention discloses a method for start-up and shutdown and a computer. By using a characteristic that a non-volatile memory is capable of storing data for a long time and fast reading and writing data under the condition of no power supply, during the shutdown of the computer, a register status value of a chip set controller, a register status value of an input/output (I/O) interface and valid data in a memory are fast written into the non-volatile memory to realize fast shutdown; and during the start-up, the register status value of the chip set controller, the register status value of the I/O interface and the valid data in the memory at the shutdown time of the computer can be fast read from the non-volatile memory to realize fast recovery of an operating system. The method for start-up and shutdown not only can realize fast start-up and shutdown of the computer, but also does not have the problem of data loss due to the off of the power supply.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for turning on and off a machine and a computer. Background technique [0002] With the development of information technology, electronic devices based on processors, such as computers (PC, Personal Computer), have been widely popularized. For a general PC, it needs to go through the basic input and output system (BIOS, Basic Input Output System) power-on self-test, operating system loading and application loading after booting. This process usually takes 1 to 2 minutes. time; and it also takes a long time to back up and save the current working data when shutting down. Especially when the PC has been used for a long time, due to the accumulation of more and more OS files, the loading time of the operating system will become longer and longer, resulting in slower and slower switching speeds. The above-mentioned problems will bring inconvenience to the user when using the PC; b...
