Lenovo motherboard jumper connection diagram

On the motherboard, there are generally connection pins marking the chassis panel, which are generally grouped at the lower left end of the motherboard near the edge. Generally, there are two rows of pins, one is * * *, and there are probably 10 groups, which mainly include pins such as power switch, reset switch, power indicator light, hard disk indicator light and speaker.

1 power switch connecting wire

When connecting the power switch cable, first find the two-pin plug marked "power sw" from the chassis panel cable, which is white and brown, and then insert it into the pin marked "pwr sw" or "RWR" on the motherboard.

2 reset switch connecting wire

Used to warm-start the computer. When connecting, first find the two-pin plug marked "Reset sw", which is white and blue, and then insert it into the pin marked "RESET SW" or "RSR" on the motherboard.

3 Power indicator cable

First, find the three-pin plug labeled "Power LED", with one wire in the middle, two wires missing, two white ends and two green ends, and then plug it into the pins labeled "PWR LED" or "P LED" on the motherboard.

Reminder: When plugging in the power switch cable and reset switch cable, you don't have to pay attention to the advantages and disadvantages of plugging and unplugging, you can plug and unplug in any way. However, the connection of the power indicator light is directional, because the LED is used to display the schedule. Some motherboards will be marked with the words "P LED+" and "P LED-". We just need to connect the green terminal to the P LED+ pin and the white wire to the P LED- pin.

4 hard drive indicator cables

First, find two plugs marked "H.D.D.LED", white wire and red wire, and plug them into the pins marked "HDD LED" or "IED LED" on the motherboard. Pay attention to the directionality when inserting. Generally, the motherboard will be marked with "HDD LED+" and "HDD LED-", and the red terminal will be connected with the HDD LED+ pin, and the Bai Duan will insert the pin marked with "HDD LED-".

5 speaker connection cable

First of all, find the four-pin plug of the "speaker", with two wires in the middle, the two ends are red and black, and plug them into the pins marked "Peak" or "SPK" on the motherboard. Red is inserted into the positive electrode and black is inserted into the negative electrode.
