For computer novices, the motherboard's power switch pinout may be confusing. PHP editor Strawberry will provide detailed guidance to help you connect the power switch pins correctly to avoid computer startup problems. The following content will provide you with step-by-step instructions and clear pictures, making it easy for you to understand and operate.
1 USB is a set of 8-wire 10-hole plugs. The side with the black wire should be inserted in the direction of one less pin on the motherboard.
2 The RST pin is connected to the reset button on the panel. ·The PO-ON pin is connected to the power-on button on the panel·(Plug it in, no requirement)
3 HD-LED is the hard disk read and write indicator light·(Note that if the positive and negative poles are plugged in, if they do not light up, reverse them That’s it.)
4 PWR-LED is the host power indicator light·(note that if the positive and negative poles are plugged in, if they don’t light up, just reverse them)
5 SPEAKER is buzzing The black wire of the device pin is negative and the red wire is positive·
6 Panel headset·The motherboard pins are a row of 10-pin double rows of pins·The second one in one row has one less pin·The actual 9 pins·
The panel connection plug is a set of 5-wire or 7-wire 10-hole plugs, one or two of which are empty (no wires). Just insert them in the direction corresponding to the motherboard pin with one less pin
1. You can open the case and find the wire connected to the power button of the case.
There are two pins on the corresponding motherboard. Shorting those two pins will turn on the computer.
Pressing the button is actually a short circuit, and the motherboard receives the signal to turn on.
(The power supply of the chassis is actually always powered on, and it is not a true power-off shutdown)
2. The power supply is plugged into the interface on the motherboard, which has more than ten wires in a bundle. Interface, short any two black and orange wires to turn it on.
3. The power switch of the chassis is connected to the motherboard of the computer through a wire. If you unplug this wire from the motherboard, you will find two pins. Use the key to shorten the two pins. That's it.
4. Pull out the motherboard electromagnet and put it back after 30 seconds. Or replace the jumper on the side of the solenoid.
The computer case has a bunch of wires with plugs. These plugs are marked with power on, reset, speak and other characters. Power on is the plug corresponding to the switch wire, and reset is the plug corresponding to the reset button. There is a row of pins on the motherboard, and there are characters marked next to it. You just need to plug these plugs into the corresponding pins on the motherboard.

Motherboard pin
The power switch cable on the motherboard needs to be plugged into the power interface. The specific plug-in method is as follows: First, find the "PWR_SW" or "POWER SW" logo on the motherboard, and then find the power switch cable from the chassis. Generally, It is a two-pin or three-pin interface, and then plug the power switch wire into the corresponding "PWR_SW" or "POWER SW" interface on the motherboard. Pay attention to the order of the two or three pins when inserting. Inserting it backwards may cause the computer to turn on. Can't stop the machine. In addition to the power switch cable, there are many other interfaces on the motherboard, such as USB interfaces, audio interfaces, SATA interfaces, etc. Each interface has its specific function. Correct insertion of the interface is a prerequisite for the normal operation of the computer. Therefore, in Before assembling a computer, you must first understand the interface types and functions of the motherboard, and follow the instructions to wire the connections correctly.
The so-called beauty is on the water side.
The residual clouds bring away the summer heat, and the new rain brings the autumn mist.
The bamboo path leads to a secluded place, and the Zen room is deep with flowers and trees.
The night comes wind and rain, Whispering Colour.
The southern neighbor is even more memorable, but the winter has not been redeemed.
Three or two branches of peach blossoms outside the bamboo are the duck prophets of the warm water in the spring river.
The bright moon of the Qin Dynasty was close to the Han Dynasty, and the people who marched thousands of miles have not yet returned.
The lake light and autumn moon are harmonious, and there is no windshield on the lake surface that has not been polished.
With the continuous updating and development of technology, many motherboards are no longer equipped with parallel port pins during design. The parallel port pin is an interface used to connect peripheral devices such as printers and scanners. However, with the popularity of USB, LAN, wireless and other interfaces, the parallel port pin is gradually eliminated. Despite this, there are still some older motherboards or applications in specific fields that require the use of parallel port interfaces, so these interfaces still exist on some motherboards for specific users or applications.
Step process:
Generally speaking, you can plug it into the position of the motherboard according to the relevant logos of the power switch, restart reset, power light, and hard disk light jumper (9Pin) on the motherboard. Basically, It's a two-pin socket.
The detailed introduction is as follows:
1. First is the power switch (POWER): The plug of this switch has two pins, one of which is indicated by yellow or black, and the other The wiring is usually white. After this plug is connected, the computer can be started through the buttons on the front panel of the chassis. In addition, it can also be started by directly shorting the POWER pin on the motherboard; there will be Power SW or PWR SW, PW, PW SW or PS logos on the motherboard;
2. The plug of the reset switch (RESET) also has two pins. One of the wires is usually purple or blue, and the other is white. The connecting plug is generally marked with the words RESET SW, and the English abbreviations near the pins at the corresponding positions on the motherboard are generally RESET, RST, RS or RE, etc.;
3. Power light (POWER LE3. Power light ( POWER LED): The power light connection is also a two-pin plug. One connection is generally indicated by green and the other is white. The plug connected to this switch is usually marked with POWER LED, and the corresponding plug on the motherboard. The English abbreviations near the pins are generally PW LED, Power LED, PWR LED or PLED and PLED-, etc.;
4. Hard disk light (HDD LED): The hard disk light connection is also a two-pin plug, with two wires connected The wires are usually one red and one white. The plug is usually marked with HDD LED, and the English abbreviations near the corresponding pins on the motherboard are generally HDD LED, HD or IDE_LED and IDE_LDE-, etc.;
Note: HDD LED is the hard disk indicator. Power is the power supply (switch). Power is the power indicator light. Restart is the restart.
1. The four red, blue, yellow and green wires on the computer motherboard. There is a problem with the connection between the cable and the motherboard. The specific connection method is to connect the front panel of the chassis to the motherboard connector, which includes the power button plug, the reset button plug, the power indicator light, and the hard disk indicator light. Find the specific corresponding position and each plug from the front panel.
2. They are all printed with corresponding English logos. Look carefully next to the corresponding pin sockets on the motherboard. They are marked with corresponding identification letters and correspond to the plugs. The pin definitions are marked for insertion. That's it, then power on and test the machine to check whether the corresponding functions are correct.
3. If there are any errors, just unplug the plug and reinsert it. Some computer motherboards are specially designed by the manufacturer, and their motherboard manuals have wiring markings. The legend guides users on connection operations, just follow the instructions
The above is the detailed content of How do I insert the pins on the power switch on the computer motherboard?. For more information, please follow other related articles on the PHP Chinese website!
