How to solve the problem that there is no response when the computer power button is pressed? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

The computer power key pressed the unresponsive solution: 1, check whether the external wiring of the computer is connected properly, reseat each connection to see if the fault is eliminated; 2, open the main chassis to see if there is any excess metal in the chassis, or the short circuit caused by the deformation of the motherboard; 3, clean up the dust on the motherboard.

The computer power button pressed the unresponsive solution:

It may be due to the above hardware reasons, resulting in aging damage of the motherboard, resulting in motherboard failure; or random hot-swappable hardware or random use of metal objects to touch various connectors, resulting in motherboard failure; it may also be caused by dust and static electricity. The following is a detailed description:

1, may be due to hardware reasons above, causing the motherboard aging damage, resulting in motherboard failure; man-made reasons: when using the computer, randomly hot-plug hardware or misuse metal objects to touch a variety of connectors, resulting in motherboard failure; dust, electrostatic reasons: due to dust or static electricity caused by poor contact with the motherboard, short circuit or burn the motherboard chip, resulting in motherboard failure. Causes of bad contact: poor contact of various chips, sockets and interfaces in the motherboard due to corrosion, oxidation, weakening of elasticity, pin de-welding, fracture and other reasons, resulting in motherboard failure

2. First of all, check whether the external wiring of the computer is connected properly, and reseat each connection to see if the fault is eliminated.

3. If the fault continues, then open the main chassis to see if there is any excess metal in the chassis, or the short circuit caused by the deformation of the motherboard, smell the burning smell in the chassis, whether there is a burnt chip on the motherboard, whether the capacitance around the CPU is damaged, etc.

4. if not, then clean up the dust on the motherboard, and then check to see if the computer is normal

5. If the fault persists, then unplug the reset cable and other switches and indicator lights on the motherboard, and then use the cone short-circuit switch to see if it can be turned on.

6. If the computer cannot be turned on, then use the minimum system method to unplug the data cable of the hard disk, floppy drive and CD-ROM drive, and then check whether the computer can be turned on. If the computer monitor shows a boot screen, the problem lies in these devices. Then connect the above devices to the computer one by one, when connected to a certain device, the fault reappears, indicating that the fault is caused by this equipment, and finally focus on checking the equipment.

7. If the fault continues, the fault may be caused by memory, video card, CPU, motherboard and other devices. Then use the plug method, swap method and other methods to check whether the memory, video card, CPU and other equipment are normal, and if there is a damaged equipment, replace the damaged equipment.
