Lenovo p 1 keeps ticking. What happened?

The following measures are recommended for the failure caused by hardware failure or poor hardware contact:

1, power off, open the chassis, clean up the dust, especially the dust of the CPU fan, and check whether the CPU fan rotates normally. Plug and unplug the hard disk data cable and power cable (this is more important).

2, power off, open the chassis, plug in the memory, use the eraser gold finger, and then plug it in (not the other way around).

3. Plug in and plug in the video card, rub the golden finger with an eraser, and then plug it in (the buckle should be fastened).

4. Unplug the power cord, take out the motherboard button cell, wait for three minutes, and then reinstall the motherboard.

5. If the above operation fails to solve the problem, it is recommended to send it to the maintenance center.
