1 People for Wake Power detection In short, it is to connect the computer motherboard 20 pin plug, with a wire (such as a thin wire, the specific people to play the imagination) a green line, a black line (there are 8), if the power supply fan

A simple method to increase AC-DC power supply power loss and keep timeAbstract: In some special applications, the conventional AC-DC switching power supply power loss holding time can not meet the requirements, and ultra-long power supply holding

The basic function of the power supply in the computer is to convert 220V alternating current into the low-voltage DC power required by the computer, generally it is difficult to see the effect on the performance of the whole machine intuitively.

Research on Low Power strategy of Embedded Linux Abstract: Power consumption is a very important performance indicator for embedded devices. After the hardware design and selection, the power consumption level depends greatly on the software design.
