1. Damaged power adapter:
①Check if the adapter is plugged into the power socket: First, ensure that the adapter is correctly plugged into the power socket and that the socket is functioning properly.
②Check if the power cord is intact: rule out whether the adapter power cord is damaged, as damaged wires may cause the adapter light to not light up. Try connecting using a different power cord and check if the light is on.
③Check if the adapter is damaged: If both of the above are correct, it is highly likely that the adapter itself is damaged. You can try using another adapter for testing. If the light on the new adapter lights up, you need to replace the damaged adapter.
