The 5V voltage is missing, it turns on briefly, but then shuts down and restarts.

This laptop is experiencing a restart problem, or it turns on and off for about 2-4 seconds. Then, it shuts down and won't turn on at all. The 5V coil voltage is missing, but other voltages are normal, such as 3.3V, and the charging current is 8.2V. After leaving it for 3-4 days, it restarts with the same symptoms, but it's still not working properly. Could you help me troubleshoot this issue?
