The power adapter indicator blinks and is tested in the following ways:
1. Use a multimeter to check if the socket is normal and the power supply voltage is 220V. If the mains voltage is not normal, it is recommended to replace the environment test.
2. Use a multimeter to check if the output voltage and current of the power adapter match the marked ones. If the gap is very large and the mains voltage is normal, you can judge that the power adapter is faulty and you need to replace the notebook power adapter.
