1. What should be the cause of contactor if the power fuse of mining machine is not broken
2. Plug in the power supply, if there is no response, this situation should be the problem of the socket, or the main power supply is not switched on
3. After the navigation host is powered on, it does not respond. It is necessary to check whether the fuse of the navigation host is broken or the main board of the host is burnt out.
4. If the system can't start at all, you can't see the power indicator light on, and you can't hear the sound of the CPU fan. At this time, first check whether the connection is well connected, whether the power line is loose, if not, it can be identified as the power part of the fault. Check whether the power cord and socket are powered, whether the power plug of the main board is connected, whether the UPS is powered normally, and then confirm whether the power supply is faulty. The simplest way is to replace it. However, it is impossible for ordinary users to have power supply and other spare parts at home. At this time, you can try this method: first connect the hard disk, CPU fan, or CDROM, Then connect the ATX motherboard power plug with a wire to two pins (the side of the plug protrudes to itself, the upper pin is the fourth from the left and the lower pin is the third from the right, the direction must be correct), and then turn on the ATX power switch. If the power fan rotates, the power supply is normal, otherwise the power supply is damaged. If there is no problem with the power supply, directly short the jumper of the power switch on the main board. If it is normal, the power switch on the chassis panel is damaged.
5. What's the main reason why the computer doesn't respond when pressing the power on key
What's the main reason why the computer doesn't respond when pressing the power on key? I believe that people who use computers often encounter this kind of situation and don't know what to do. Improper operation and computer hardware problems may be the reasons why computers don't respond when they turn on. So what can we do to make computers return to normal when computers don't respond when they turn on
computer hardware problems
the first symptom is that the computer does not respond after pressing the power button of the computer. The most common reason is hardware problems: hardware problems can be specific to various computer components and connecting lines, and can be found through the following methods. One is the computer power aging caused by voltage instability, power shortage, the common symptom is the computer power flash out. At this time, you can try to unplug the power cord and plug it in again. If not, keep looking down< br />

Second, there is a problem with the connection line. Since the power supply is not good, you can try to plug in the hardware connection lines in the computer chassis on the motherboard again. Loose connection lines will also cause the computer to turn on and not respond
thirdly, the computer is not taken care of properly. Compared with the old machine, the st in the computer case needs to be cleaned regularly, otherwise the st on the main board, the st on the CPU fan and the st on the computer power supply may make the computer fail to start. This is a good solution. Just use a cleaning tool to blow the st on the computer carefully< br />

Fourth, there is a problem with the display. When the computer is turned on, it doesn't respond. Sometimes, it means that the computer can run, but the computer display doesn't respond. You just need to change a display to know if it is a problem with the display. If it's a display problem, it can only be repaired at the maintenance point
fifthly, it's the problem of the computer graphics card. In the fourth step above, it can't be displayed after changing a monitor. That may be the problem of the computer graphics card. Most of the problems of the graphics card are caused by the computer memory. Try to open the chassis to clean up the st on the memory and plug in the computer memory on the integrated graphics card again, or try to change a memory< br />

if the above methods can't find the reason why the computer doesn't respond to power on, don't find the reason by yourself. It's recommended to take it to the maintenance point to check the reason. The second symptom is the computer boot chassis reaction, but the system can not get in or error, black or blue screen. This is not the problem that the computer does not respond when it is turned on, but the problem that the computer cannot enter the system when it is turned on. The solution to this problem can be found in another piece of my experience: the computer cannot enter the system when it is turned on.

6. The power supply should not be broken. If the power supply is broken, the host lamp will not be on. It is suggested that you plug in the link line again. This is what happened when you installed a new machine last time!!!
7. There are the following faults in the wireless router when the power light is not on.
fault 1: the power adapter may be aging or damaged.
fault 2: check whether the power adapter is original, and the voltage limit of each router is different, so it can not be mixed
fault 3: replace the socket panel, it is possible that the socket panel and the voltage adapter have poor contact
the above faults can be eliminated, and the router can judge that there is a hardware problem. If it is within the warranty, you can choose the nearest repair site for repair.

8. When I see the similar problems, my personal views are as follows:
1. The fault is locked in the power supply part
2. Check whether the socket has AC 220 V power supply
3. Take off the power supply and test it separately... Plug in the socket with electricity, and use the maintenance tool tweezers to short the green and black wires of the power supply; If the fan turns, it is the normal power supply
4. If it does not reflect, the fault is the power supply fuse or the switch tube is damaged ·
5. It is recommended that you find a professional computer maintenance department to solve the problem····
