حل مشكلة هواوي P9 لايعمل/درجة حرارة البطارية مرتفعة

Huawei P9 No Power On/Battery Temperature

The current is reset to zero at around 129ma. It cannot be turned on normally.

 

1

Firstly, the overall appearance of the machine is detected. The tail screw is not. After disassembling, the shell detection board finds the battery connector interface J1501.

View the circuit diagram. This original is the R1501 pull-up resistor. The main

CPU detects a battery temperature and an 18k resistor is damaged.

The current jump is not normal and does not open.We found a 18k resistor replacement test.

The boot current is normal, and the battery is turned on as shown in the figure

حل مشكلة هواوي P9 لايعمل حيث يعطي قيمة 129 ميلي آمبير ويعود للصفر

و يعطي أثناء الشحن مؤشر درجة حرارة البطارية مرتفعة

تم الحل بإستبدال المقاومة 15 كيلو أوم
