Embodiment Construction

[0039] In the following embodiments, when the computer system enters the standby / shutdown state, it can stop supplying a part (or all) of the electronic components' standby power, and enter a simulated no-power state, and when there is a work demand (such as receiving wake-up event) can return to the normal working state from the simulated no-power state in time, in order to achieve the best power-saving effect. In addition, in the following embodiments, the normal working state includes S0, and the standby / off state includes one of the standby state S3, the sleep state S4, and the shutdown state S5, and the simulated power-off state is represented by G3' or G3" The simulated no-power state G3' / G3" referred to here is similar to the no-power state G3 in the Advanced Configuration Power Interface (ACPI) power management system, wherein the output provided by the simulated no-power state G3' / G3" The power supply type only includes battery power V BAT as well as a fraction of th...

Abstract

The invention provides a computer system for saving power consumption in standby / power-off state and a related method thereof, the method comprises a plurality of electronic components and a switching control circuit. In the invention, when the computer system receives a standby / power-off instruction in a normal operation condition, the switching control circuit controls the computer system to switch to a standby / power-off state from the normal operation condition and stops outputting a standby power source containing at least one standby voltage level to at least a part of the electronic components in a plurality of the electronic components, and at this time, the computer system enters a simulated state without power from the standby / power-off state. The number of the electronic components which are supplied power by the standby power source when the computer system is in the simulated state without power is less than that of the electronic components which are supplied power by thestandby power source when the computer system is in the standby / power-off state.

Description

technical field [0001] The present invention relates to a computer system and related method capable of saving power consumption, especially a computer system and related method capable of saving power consumption in standby / shutdown state (such as power state S3, S4, S5). Background technique [0002] In recent years, there is an increasing demand for energy saving in electronic products. According to the specifications of the Eco-Design Requirements for Energy Using Products (EuP) announced by the EU in 2005, the design of future computer products must meet the specifications before they can be imported into the EU. The first stage is to stipulate that the power consumption of the computer system in the standby / off state must be less than 1 watt, and after 2013 AD, the power consumption of the computer system in the standby / off state must be less than 0.5 watts. In order to meet the requirements of the new law, the present invention proposes a power-saving mechanism for t...
