  When we were using the power adapter, we suddenly found that the power adapter indicator light is not on. There are many factors that the indicator light does not turn on. So what are the reasons for the power adapter indicator light off? Next, the power adapter manufacturer will explain it in detail.

Analysis of the reason why the indicator light of the power adapter does not light up(图1)

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

  2. Check whether the external adapter is correctly 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 repair point for repair or 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 to see if the fault can be eliminated, or all are normal but the light does not light, so it may be that the indicator light is aging.

  Consumers don’t know much about the aging test. The aging test is very important in the power adapter to detect what is wrong with the power adapter. Next, the power adapter manufacturer will explain in detail why the power adapter needs the aging test. .

  In fact, many power adapter products on the market have not undergone aging tests. Why do you say that? First, most of the power adapter products that flow out of the production line already have all their functions and can be used directly .

  However, if you don’t do the aging test, then there may be many problems in the initial stage of the power supply, such as short circuit, no voltage, no current, and even explosion. However, these problems can be completely avoided after the aging test. Of course, use a If there is a problem in a year or more, it is a problem with the life of the power supply, and there is no way to control this.

  Of course, this problem cannot be said to be so absolute. Our analysis is only a theoretical result, because it does not rule out that you have bought a copycat product that has not been aging tested, but it is no problem to use it, maybe it takes a year or two. There is a problem, but the power adapter products that have been aging tested are safer.
