System and method for switching on between operation-state and stand-by state of computer

Abstract

A method for switching over computer from operation state to standby state includes switching off central processor operation power for entering it into standby state but keeping operation power on multiple peripheral devices by power management unit when operation state is switched on standby state, detecting action of computer system by detection unit and switching on central processor operation power for entering it into operation state when a wake up signal is detected up by detection unit.. A computer unit for realizing the method is also disclosed.

Description

technical field [0001] The invention relates to a method and a computer system for switching between a working state and a standby state. Background technique [0002] For computer systems, saving power and reducing heat generation of the computer system are two very important things, especially for portable computer systems such as notebook computers. Especially when carrying this portable computer system, only rely on the battery as the power supply source, so the limited battery power often can only provide the operation time of the computer system for several hours, so how to save power is very important. In addition, in order to be easy to carry, under the premise of light, thin, short and small design, due to the increasingly smaller and denser component design of notebook computers, coupled with the continuous improvement of operating performance, it is difficult to dissipate heat in a small space However, the continuously rising temperature will easily cause crashes...

Problems solved by technology

In addition to the problems of complex circuit design and increased cost

[0006] Moreover, according to the different signal voltage values ​​on the board, such as working power, standby power, and dual power switching between working and standby power, etc., it is necessary to plan different voltages on the board when designing the circuit. The circuit area of ​​electric energy, such as the main power plane, the standby power plane, or the dual power plane, so that there may be circuit components with different power requirements in the circuit design , the so-called cross-cutting circuit design that must cross the circuit area of ​​​​different power, so that the overall performance of the board is not good.

[0007] Moreover, the power consumption and heat generation of the board are mostly caused by the CPU

Therefore, in order to achieve the purpose of saving power of the computer system and reducing the heat generation of the computer system, and to avoid the above-mentioned problems such as startup failure, complicated circuit design, and cross-cutting design, the present invention provides a switch between the working state and the standby state. method and computer system to solve the above problems
