The boot button of the main machine is broken, how to turn it on

Find the power or PW pin on the motherboard, if it is still connected to the power button, you can see it along to the motherboard, and use a screwdriver to short-circuit it.

..If you don't disassemble your computer often. I'm afraid it's more troublesome.

The easy way to do this is: Unplug it first! ,, disassemble the chassis, and then find the two wires connected to the boot button and cut it at the place where the button is connected, and then remove the switch with a screwdriver, and then take it to the electronic parts store (or computer city can also be) to buy the same back (generally only the switch part can be bought without the shell) and replace it, and finally tie the wire directly to the same position of the button (if possible, solder it with an electric soldering iron, forget it!

The easiest way: Send it for repair!

Also: Are you sure all the cord parts are fine?

You can change the reset to a switch by unplugging the POW SW from the motherboard and plugging the RST in.

Turn on the power as soon as you connect the positive and negative poles!

Short-circuit the two wires on the button directly to turn on the machine, and separate when you see the fan turning, otherwise it will turn off again.

Lead out the two wires of the boot button by yourself.

If you want to turn it on, you can touch it, haha.

Under normal circumstances, there will be a power on and off button on the motherboard. Temporary transitions are possible. Take a ** go to the computer city to buy a button and come back. If the cable is broken, it is recommended to replace the cable together.

Go buy another one, otherwise it's very inconvenient, it's to change the computer boot button, not to change the computer.

The computer host key is broken, a common hardware glitch. The main reason for this is that the switch is pressed for a long time, resulting in the failure of its internal spring or poor contact of the internal circuit.

Open the case, there is a bend in the front panel of the case to connect to the motherboard, that cable has four rows of pins on the motherboard, one row is the control hard disk indicator, one row is the power indicator, one row is the reset switch, and the last row is the power switch. Each of the four rows of switches has two pins that are positive and negative, and the plastic sleeves of these four rows of wires can be pulled out (but the order must be remembered, because they must be put back according to the position), and their functional names should be clearly marked on these sleeves, and the power supply should be written with power.

Solution: 1. It is estimated that the reason why the switch does not work is either that the wire is broken, or because of the poor conductive contact caused by the oxidation of the metal pin surface on the motherboard. Because the two pins of the power supply on the motherboard are one positive and one negative, you can also turn them on by shorting them with a screwdriver, so you can know whether it is the problem of the pins or the wires.

2. Replace the power switch and restart switch by yourself, that is, socks first unplug the power switch plug-in from the motherboard pin, and then plug the infrequently used restart switch cable into the motherboard power switch pin, and you can use the restart Tianguan as a power switch.

3. If the ability of the expert is limited, it is recommended to send it directly for repair and replace it with a new switch.

The power on and off button can be replaced by yourself, but it is difficult to match it to the same size.

There are many switches that sell on the Internet, and you can buy one.

Then open the case, look at the two pins that the current switch plugs into, and replace the one you bought.

Dismantle the machine box baiI remove the front cover. Remove the boot button. Go to 2 lots and buy the same press.

DAO button. Cut the thread.

Return. Connect the two wires separately. Don't mix.

A single answer to a single does not divide the black. Just pick up the button you bought. If not sold.

Just buy an old machine box 20Left and right I bought it. Just get the power on button down and replace it.

It's more convenient that way. It is better to follow the line directly. If the other side is plugged in, there is no need to cut the wire.

If you are sure that it is a switch problem, you can open the chassis, the switch generally has a pair of wires, you can go to the daily miscellaneous to buy a doorbell switch, cut the original wiring carefully, and connect the two wires of the doorbell switch to the cut wire instead of the computer switch.

I'm going to go.,The switch will also be broken by you.,You said that it crashed after booting up bai shouldn't be.。

The problem with the DU switch is that DAO frequently crashes when using the IE browser? That's your system conflict.,Buy a system disk.,I think sp2 is the most stable.,It's OK to change the system.,If it's switched....Take it to the computer repair place and fix it, it won't be very expensive...

Brother hit it by hand, I'm sorry for your brother if you don't give points.

If you can disassemble the switch, remove it and ask them to repair it at the place where the TV is repaired, the cost is less than one yuan, and you may be charged 5 to 10 yuan for repairing it. If you can't dismantle it, then go with the computer.

If you change the switch, you will definitely not be able to install it, even if there is a part, you can't install it. A lot of editions on the street.

Computer repair center, if you feel that the right maintenance center is unreliable, you can also go to some computer city, digital city. Anyway, it's a large maintenance center If you don't know in**, search for your place on Google Maps, there should be one.

Dismantle it all and then take the switch button down and oil it.

It's still not successful, go to the sleeve computer, where to change the switch.
