1. Arrange all the wires together. According to the above markings, first clarify the definition of each wire:
a. Power switch: POWER SW, possible names: POWER, POWER SWITCH, ON/OFF, POWER SETUP, PWR, etc. Function definition: reset button on the front of the chassis.
b. Reset/restart switch: RESETSW, possible names: RESET, Reset Swicth, Reset Setup, RST, etc. Function definition: power-on button on the front of the chassis.
c. Power indicator light: +/- Possible names: POWER LED, PLED, PWRLED, SYS LED, etc.
How to connect the power-on button wire on the computer motherboard:
1. Arrange all the wires together. According to the above markings, first clarify the definition of each wire:
a. Power switch: POWER SW, possible names: POWER, POWER SWITCH, ON/OFF, POWER SETUP, PWR, etc. Function definition: reset button on the front of the chassis.
b. Reset/restart switch: RESETSW, possible names: RESET, Reset Swicth, Reset Setup, RST, etc. Function definition: power-on button on the front of the chassis.
c. Power indicator: +/- Possible names: POWER LED, PLED, PWRLED, SYS LED, etc.
d. Hard disk status indicator: HDD LED, Possible names: HD LED
e, built-in small speaker (or alarm): SPEAKER, possible name: SPK, function definition: alarm for abnormal motherboard operation.
f. Audio connection cable: AUDIO, possible name: FP AUDIO, function definition: chassis front audio, generally a whole.
g, USB connection to the front interface is generally a whole.
2. Find the location of each pin on the motherboard.
You can connect in the following ways:
1. Find the plug with the POWER (PWR) mark on the chassis panel, find the corresponding marked pin on the motherboard and insert it.
2. The chassis wiring is often marked with their respective identities in English, or English abbreviations, just like the model number of the monitor. Players can easily distinguish them through such logos. It's okay if you don't know what the letters mean, there aren't many types of wiring.
The row of pins on the motherboard where the power cord is plugged in is called the "system panel connector", which is the interface that connects the motherboard to the front panel of the chassis. This interface usually consists of 9 pins and is used to connect the power switch, reset switch, power and hard disk activity indicator lights on the front panel of the chassis. Connections to this interface are made through a simple set of plugs and sockets, usually marked with + and - symbols. Correctly connecting the system panel connector is one of the important steps in installing the computer. It can ensure that the control buttons and indicator lights on the front panel of the chassis work properly, and it can also ensure the normal startup and operation of the computer.
The interface of the Lenovo computer startup switch cable is usually a two or three-pin plug, which needs to be connected to the corresponding position on the motherboard. The specific steps are as follows:
1. Open the manual of the computer motherboard and look for the connector location marked "Front Panel" or "System Panel" on the motherboard.
2. Find the pin definition table of "Front Panel". The function and location of each pin will usually be indicated in the motherboard manual.
3. According to the pin definition table, plug the computer start switch wire into the corresponding pin. Generally speaking, the labels of these pins include: Power SW (power switch), Reset SW (reset switch), HDD LED (hard disk indicator light) and Power LED (power indicator light), etc. These labels are usually identified in the motherboard manual and on the motherboard.
4. Make sure the computer startup switch cable and other cables are firmly plugged in, and the interfaces are not loose.
5. Close the computer case, connect the power cord, and try to start the computer to ensure that the computer is working properly.
Notes:
1. You should be careful when wiring to ensure the pins are correctly aligned and press the plug gently until it is fully inserted.
2. Before connecting the computer startup switch cable, make sure the computer is powered off and the large capacitor on the motherboard has been discharged.
3. If the connector of the cable is not labeled or the label is unclear, you can determine the location of the pins according to the marks on the computer case.
How to connect the desktop computer host’s boot cable:
1. Arrange all the cables together. According to the above labels, first clarify the definition of each cable:
(1) Power switch: POWER SW, possible names: POWER, POWER SWITCH, ON/OFF, POWER SETUP, PWR, etc. Function definition: reset button on the front of the chassis.
(2) Reset/restart switch: RESETSW, possible names: RESET, Reset Swicth, Reset Setup, RST, etc. Function definition: power-on button on the front of the chassis.
(3) Power indicator light: +/- Possible names: POWER LED, PLED, PWRLED, SYS LED, etc.
(4) Hard disk status indicator: HDD LED, possible name: HD LED.
(5) Built-in small speaker (or alarm): SPEAKER, possible name: SPK, function definition: motherboard abnormality alarm.
(6) Audio connection cable: AUDIO, possible name: FP AUDIO, function definition: chassis front audio, generally a whole.
(7) 7USB is connected to the front interface, usually as a whole.
2. Find the location of each pin on the motherboard.
3. After all connecting cables are plugged in, check whether all hardware is installed correctly and is solid. Also check that all connections are correct and secure.
4. After the inspection is completed, press the power button on the chassis and check whether all the indicators are normal.
5. After the indicator light is normal, use a USB flash drive and headphones to check whether the front USB and front audio are normal.
6. Check that everything is normal and then close the chassis. The cable connection work is completed.
Plug in the four wires to start the computer as follows. There are four sets of wires on the computer panel, namely the power-on indicator wire, the hard disk wire and the restart wire. They are two rows of steam on the motherboard. There are four dumplings in a row and five in a row. The top four pins from right to left are the switch line indicator lights, and the bottom five pins from left to right are the hard drive line and restart line
The computer case boot cable is plugged into the power socket on the motherboard. There are generally four sets of cables on the computer case, namely the sound card, hard drive power supply and reset cable. Among them, the plug of the power cable is marked with the word "power". We Find the socket set of the Jixiang line on the motherboard. The two pins in the upper right row are the power cord sockets. Just insert the power plug into these two pins.
The computer motherboard switch is usually located on the lower left front of the motherboard. A computer motherboard, with the CPU at the top and sockets for the mouse, keyboard, USB port, network card, sound card, etc. at the back. The power switch pin is on the lower left front of the motherboard, usually with the reset switch, hard disk indicator light, and power supply. lights together.
