How to arrange the switch wires of the host and how to plug in the switch wires of the computer host

1. Generally, in the lower right corner of the motherboard, in the corner of the south bridge, there should be small words next to some pins marked with the role of the pins

Reset key, PW, power switch, HDD

LED --- hard drive indicator PW

LED --- power indicator speaks

-The speaker has no polarity except for the indicator light, and the line black of the LED corresponds to the pole.

Color correspondence + pole.

2. The switch line of the computer is power

There are English words on the sw connector) directly plugged into the first row of three or four to realize the switch on and off the computer, and the restart button corresponds to reste

sw is also directly plugged into the three or four pins of the second row, and the following is the hard disk light, which is the second in the first row and the second in the second row. It's best to just plug in the first or second row of dead power lights.

The main unit refers to the main part of the computer other than the input and output equipment. It is also used to place the mainframe of the main board and other major components. This typically includes CPU, memory, hard disks, optical drives, power supplies, and other input/output controllers and interfaces.

1.Locate the plug with the Power (PWR) logo on the chassis panel, and insert the pins on the motherboard.

2.Often the wiring of the chassis will identify their respective identities because of the English abbreviated subtitles alive, just like the model of the monitor. With this logo, players can easily distinguish them.

It doesn't matter if you don't understand the meaning of these letters, there aren't many kinds of these wiring.

Look at what is written on the motherboard. on off is the switch? It's the upper right corner of the **, you insert the yellow and white needles.

The next two are the restart switch.

The host power sw is the switch. Positive and negative can be indistinguishable.

reset sw is a restart, and positive or negative can be indistinguished.

I sent you an installation tutorial.

Interfaces for different motherboards.

The location is not the same.

But hair extensions are all the same.

The best thing to do is to follow the instructions on the motherboard.

These connectors are located on the upper edge of the motherboard.

The interface is needle-like.

Also called skipping needle.

between the chassis and the motherboard.

If so. The brand of the motherboard.

Let's talk about the specific model.

If the enemy makes you angry, it means that you are not sure of defeating him; If a friend makes you angry, it means that you still care about his friendship.

Power Power Switch REST Reboot HDD LED Hard Drive Indicator Power LED Switch Indicator.

You take a look at the power power switch rest reboot hdd led hard drive indicator power led switch indicator that is available on the motherboard.

There is PW or RESET marked on the motherboard, PW is the power supply, and RESET is the restart.

Marked on the line and on the motherboard.

From the picture, there is no problem, the monitor is connected to a discrete graphics card, and the power supply is plugged in normally. It is recommended to wipe the memory module, graphics card, etc. with an eraser.

This line looks normal.

We need to open the case to see if there are any substances such as metal in the case, which causes a short circuit in the computer host circuit, and then we smell the computer to see if there is a burning smell, and see if there are damaged components around the motherboard and around the CPU.

After inspecting the entire chassis and there is nothing abnormal in the chassis, then we will dust the chassis.

If it can't be turned on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

If the fault still exists, it is likely to be the fault of the memory card, graphics card, CPU, motherboard, etc., at this time, we only need to plug and unplug these hardware, or replace it again, and try to find the cause one by one.

If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can display, then install the motherboard into the chassis for testing until the cause of the fault is found. If the fault persists, you need to return the motherboard to the manufacturer for repair.

The diagram above shows the wiring connection at the rear of the computer's main unit. The switch button connection of the main computer is on the front panel of the main unit. If the boot does not respond, it may be caused by a power failure, a quality defect in the memory, a failure of the CPU or motherboard, a poor contact of the switch button or an incorrect connection with the front panel pins on the motherboard, etc., and you need to check to find the source of the fault.

It is difficult to see what the problem is just from the rear line connection of the main unit in the picture above. You can open the case, temporarily disconnect the hard disk and optical drive, keep only the memory, CPU, and graphics card (if any) on the motherboard, and try to find the source of the fault by booting the system with minimal system.
