Although this prior art approach can be applied to the same batch of computer motherboards of the same design, for another batch of computer motherboards of different designs, a special design must still be carried out for this batch of computer motherboards, so that it can be applied to The batch of computer motherboards
This kind of prior art causes the cost of repeated design, which virtually increases the manufacturing cost of the computer motherboard

Embodiment Construction

[0027] See figure 1 , figure 2 . For the purpose of disclosing the convenience and easy understanding of the present invention, in figure 1 , figure 2 In the figure, the computer motherboard 20 only shows the hardware components directly related to the present invention, but other components belonging to the computer motherboard 20 are omitted as long as they are not directly related to the present invention. The main function of the electronic device 10 that consumes power when the mainboard of the computer is turned off in the present invention is to isolate the power supply 30 (Power supply), for example: ATX power supply, and its constant power 30a (stand-byPower) from entering the mainboard of the computer 20 Before, for example: 5V (or 3V) constant power. After the computer motherboard 20 is soft off (Soft off), the electronic device 10 cuts off a part of the electronic components on the computer motherboard 20 that consume the constant power 30a, and only supplies...

Abstract

The invention discloses an electronic device for reducing shutdown power consumption of a computer mainboard and a computer mainboard. The electronic device comprises a first device and a second device, wherein the first device is used for controlling the constant standby electricity of a power provider to form a close circuit or an open circuit with the computer mainboard; and the second device is used for receiving power switch signals generated by a power switch, enabling the first device to control the constant standby electricity to form a close circuit with the computer mainboard after receiving the power switch signals, copying the power switch signals, outputting the power switch signals to the computer mainboard and enabling the first device to control the constant standby electricity to form an open circuit with the computer mainboard when judging an S4 state or an S5 state of an ACPI. The first device and the second device are electrically connected to the constant standby electricity. In the invention, the computer mainboard can automatically achieve energy saving just as entering G3 mechanical shutdown of the ACPI when the ACPI is in an S5 soft shutdown state.

Description

technical field [0001] The present invention relates to an electronic device for reducing the power consumption of computer motherboards when they are shut down, and in particular to a computer motherboard that is in the ACPI S5 soft off (Soft off) state, which will cause the computer motherboards to appear as if they have entered ACPI G3 mechanically. Shutdown (Mechanical off) the same. Background technique [0002] At present, the existing computer mainboards that conform to the Advanced Configuration and Power Interface (ACPI) specification enter the S5 soft off (Soft off) state, but due to the hardware design factors of the existing computer mainboards, they still It is impossible to effectively reduce the power consumption after shutdown. At this time, if the existing computer motherboard adopts parts with high power consumption, it will not only fail to save energy, but will consume more power, which will virtually cause waste of electricity bills. [0003] In order t...
