Since it is a laptop power adapter in use, suddenly smoke out of the water, indicating that the power adapter inside the large electrolytic capacitor damage, flow of the liquid.
This happens, are the power adapter inside the AC 220V rectifier circuit output rectifier voltage filter caused by large electrolytic capacitor damage. There are several reasons for its damage:
Power adapter for a long time work, power tube hot, resulting in electrolytic capacitor temperature damage. Because the electrolytic capacitor is installed near the power tube.
Power supply voltage fluctuation caused. Because the power adapter manufacturers in order to reduce the size and cost of the power adapter, the electrolytic capacitor voltage selection is relatively low, in the mains fluctuation beyond the design range, resulting in electrolytic capacitor breakdown damage.
Itself electrolytic capacitor quality is poor, the common capacitor insulation between the plate damage.
Because the electrolytic capacitor inside the use of electrolyte to increase the capacity, once the electrolytic capacitor shell damage, the inside of the electrolyte will flow out.
DELL1420 notebook computer in use, the power adapter suddenly smoke issued Chi Chi sound, the adapter assembly cracks out of a little light yellow water; I immediately unplug the power, open the adapter, see a small amount of water out there, I would like to ask What's the matter?
