Problems solved by technology

However, the graphics card does not automatically adjust the corresponding operating parameters according to the operating mode of the motherboard. Therefore, in terms of overall computer power management, whether it is performance improvement or energy saving, the coordination of convenience and power adjustment needs to be strengthened.
[0004] In addition, since the operating voltage and frequency of the motherboard and the graphics card are not necessarily the same, in the known technology, when the motherboard performs dynamic energy saving, the graphics card will not automatically adjust to an appropriate working mode, resulting in a gap in power efficiency and making the overall computer The energy-saving benefits of the

Abstract

The invention relates to a power management method for a main board and a display card thereof. When the main board is switched to a second efficiency mode from a first efficiency mode, a microcontroller in the main board can output an adjusting signal to the display card through a special connector to correspondingly adjust the working parameters of the display card, thus the integral effects of a computer on saving energy and improving efficiency can be better.

Description

technical field [0001] The invention relates to a motherboard, and in particular to a motherboard and a power management interface capable of simultaneously managing the power usage efficiency of the motherboard and a graphics card. Background technique [0002] The issue of global warming has made energy-saving concepts popular, and computer-related equipment has begun to pay attention to the related designs of energy-saving concepts. Various motherboard manufacturers have also begun to incorporate designs with energy-saving concepts into their motherboards. Current motherboards can apply dynamic energy-saving technology to reduce power consumption. Dynamic energy-saving technology mainly uses multi-stage power circuit design, so that the power module can provide different power for the motherboard according to different loads and power requirements. Thereby, the power consumption of the motherboard can be reduced and the power efficiency of the motherboard can be improved....
