The indicator light of the power adapter keeps blinking, which is usually caused by the unstable internal of the adapter.At this time, it is likely that the internal voltage is unstable.In this case, it is recommended not to use the power adapter.The cause of this situation is mostly the failure of the power quality, such as Built-in rectifier large capacitor cracking or bulging, etc. 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 turn off the power to see if the fault can be eliminated, or all are normal but the light is not on, so it may be that the indicator is aging. If you cannot find the problem, it is recommended to take it to a professional maintenance point for repair or replace the power supply.ģ. Check whether the external adapter is correctly connected to the powered device, and whether the external power adapter is working properly. The indicator light on the power adapter is off, then the adapter may not be connected to the socket, or there is no power at the socket, or the adapter may be broken.Ģ. The internal failure of the power supply has caused hiccups in the power adapter, most of which is due to the failure of the filter capacitor. If the fault persists, we need to check the DC interface to see if it is damaged, such as loose or damaged appearance, it is recommended to try to replace the DC head.Ĥ. If the powered product is other, you can refer to this method.ģ. Press and hold the laptop power button for 5 seconds and repeat 3 times to release the residual charge of the laptop and insert it separately Power adapter, power on test. If the above check is normal, if the powered device is a laptop, we can remove the laptop battery and do not connect the external power adapter. If they do not match, and the mains voltage range is normal, it can be judged that the power adapter is faulty and the power adapter needs to be replaced.Ģ. Use a multimeter to check whether the output voltage and current of the power adapter match the ones marked on the nameplate. If the mains voltage is abnormal, it is recommended to replace the use environment test.ġ. ![]() When troubleshooting, first of all, we use a multimeter to check whether the socket is normal, whether the power supply voltage is 220V, and the maximum does not exceed the range of 100~240V. Or if the output is normal but the indicator flashes, it may also be a problem with the LED display. It may be that the external voltage is too high or too low, and it is more likely that the external short circuit or external overload caused repetitive startup. At this time, the internal voltage is likely to be unstable. If there is a flashing failure, there may be several reasons, which may be caused by internal instability. binder products are used in agricultural and construction machinery, signal equipment, machine tool construction, medical technology, measuring technology as well as sensor and automation technology.The indicator light of the general power adapter only shows whether the power supply is working normally. Our product range extends from sub-miniature connectors to multi-pin machine connectors.
