After receiving the machine plug-in data cable, it is found that there is no current, so it is directly disassembled for testing. If the motherboard is not short-circuited, it can be turned on directly by using the regulated power supply, so it can be repaired and charged. After measurement, it is found that the tail plug-in 5v does not reach the motherboard, so it should be that the tail plug-in is broken. A new tail plug-in test 5v can be sent to the motherboard, and the button screen test charging is normal.
