My Lenovo S939 suddenly turn off and when power on back, it just beeping or vibrating. I put it on charger and red led lights up (meaning is charging) for few minutes then stop. Some people says it is motherboard problem but i wish to know what part specifically cause it. Is it charging fault or ic damage? No drop or water damage happen just before it turn off suddenly.
If it is continuously beeping and vibrating then it is a logic board problem, it’s hard to say exactly what is wrong with the board but you wouldn’t really be able to change the boards components without special devices so…
