  When we are using the power adapter, we suddenly find that the indicator light of the power adapter is not on, and the indicator light does not light up. Next, the power adapter manufacturer will explain it in detail.

  1. If the indicator light on the power adapter is not on, it may be that the adapter is not connected to the socket, or there is no power at the socket, or the adapter may be broken.

  2. Check whether the external adapter is properly connected to the powered device, and whether the external power adapter is working properly. If you can't find the problem, it is recommended to take it to a professional maintenance point for overhaul or to replace the power supply.

  3. In addition, you can also use a multimeter to check whether the output voltage of the power adapter is normal, whether the socket is loose, and re-power off the power to see if the fault can be eliminated, or all are normal but the lights are not on, so it may also be that the indicator lights are aging.
