Low battery. You can connect the headset to the power cord to see if it can be charged normally. The indicator is damaged. After connecting the power cord, the indicator light is not bright, but open the mobile phone, you can normally check the headset power and charging capacity, and the headset can also be used normally, which proves that there is a problem with the indicator light. In this case, you can go to the official direct store for after-sales maintenance. There's a problem with the headset battery.
The Bluetooth headset into the charging bin does not light up may be due to a variety of reasons, bagThese include battery problems, charging bin problems, or connection problems. Battery problems: The Bluetooth headset is not properly charged, or the battery has been damaged, which may be the cause of the failure to light up the charging bay. Try using a different charging cable or replacing the battery to fix the problem. Charging bay issues: The charging bay may malfunction or be damaged, resulting in incorrect charging.
may be the reason why the Bluetooth headset has not been used for a long time, the headset itself has a "self-protection" function, in a "closed" state, if this happens, you can charge for a few minutes or dozens of minutes to see if the indicator light is on.The connecting wires connected to each socket fall off and oxidize, and the connecting screws of the wires through the core are not tightened. Air switch trips or breaks. The neutral line of the plug bar is broken, and as long as there is a live line in the socket, the indicator light will be lit without the neutral line.
Check the power adapter indicator light, if the indicator light is on, it is generally believed that there is no problem between the power supply and the adapter, and it must be ensured that the indicator light itself is not broken. Check that there is no electricity between the power adapter and the computer.

1, the main power line between the knife and the lamp is damaged, so it is the same fault. Regular wiring, are divided into floors, electrical appliances, the use of different distribution boxes, so set up a large current with (kitchen, bathroom, socket, air conditioning), small current with (lighting, outdoor lights, storage room lights), these two circuit wires are from the main gate out of the branch knife, the load is separate out of the line.
