The host switch doesn t respond, and sometimes it can be turned on and can t be opened, what s going

It should be a problem with the switch.,That's the way it is at my house.,It's good luck to press a few times to turn it on.,If you're unlucky, you can't turn it on.。 I'm also too lazy to repair.,Just set the host to power on.,It's pretty good to use.,It's to turn off the power of the host every time you turn it off.,The next time you turn on the power, just turn on the power directly.。 I forgot how to set it up, you can search for it yourself.

Be careful not to turn off the power directly when the computer is shut down, which will hurt the computer. Wait until the system is turned off before turning off the power.

1. Because of your memory, the dust has also been cleaned up, but the CPU fan is not running, which means that the motherboard has no normal voltage input, so you can first determine that there is a problem with the power supply of the host.

2. When the switching triode, rectifier diode, filtering large capacitor, transformer, main IC chip, performance decline, performance is not strong, etc., although there is still voltage, but it has been unable to provide sufficient voltage to drive the host with normal dismantling, and it cannot reach the normal input voltage and current of the host, so it cannot start the computer, but because the power auxiliary circuit of the host is normal, there is a bright light on the keyboard or mouse, and the voltage can also be measured. You can also use an electronic multimeter to further determine the quality of the power supply, short circuit 13 and 14 green wire and black wire (will not be electrocuted, safe voltage), generally at this time the power supply fan will definitely turn, this is a judgment method, there is also a voltage measurement method: short pull the green line and black line, use the black watch pen to connect the black line, the red table pen respectively measure, standby voltage, purple whether there is 5v, whether the red line is about 5 volts, whether the orange line is in, whether the green line is about 5v, whether the blue line is 12v, Whether the yellow line is 12V, if these parameters are normal, it means that the power supply is not ruined, otherwise, it is broken.

3. Through the above two steps, you can determine that the power supply is broken, as long as the power supply is replaced, the problem will be solved, and the machine can be turned on.

There may be several reasons why the switch can't be turned on:

1.Incorrect installation: When the switch is installed, the switch base needs to be fixed on the wall, if the base is not fixed, the switch cannot be hit.

2.Wrong line: If the line is wrong, the switch will not work properly and will not be able to be plugged in.

3.Damaged switch: If the switch itself is damaged, it won't work properly and won't be able to hit it.

4.Uneven wall: If the wall is uneven, the switch will not fit perfectly with the base and will not be able to be hit.

Workaround:1Check whether the base is fixed, if not, relight the new installation.

2.Check whether the line is connected wrong, and if it is wrong, re-wire.

3.Replace the switch, if the switch itself is damaged, you need to replace it with a new one.

4.Trim the wall, if the wall is uneven, you need to trim the wall to make it flat.

There may be several reasons why the switch won't work:

1.Incorrect installation: When the switch is installed, it is necessary to fix the base of the Kaitong rotten off the wall on the wall, if the base is not fixed, the switch can not be hit.

2.Poor wire contact: If the wire is not in good contact, the switch will not work properly. You need to check that the wires are plugged in tightly.

3.Damaged switch: If the switch itself is damaged, it won't work properly. A new switch needs to be replaced.

4.Loose switch base: If the switch base is loose, the switch will not work properly. You need to check if the base is secured.

5.Incorrect Switch Slow Installation Position: If the switch is installed in the wrong position, the switch will not work properly. You need to check that the switch is installed in the correct position.
