My Toshiba Pa3468u-1aca Ac Adapter Has Encountered Such A Problem

A few days ago, my Toshiba PA3468U-1ACA AC Adapter has encountered such a problem: the ac adapter has gone out of work

. That is to say, the notebook computer only works with the laptop battery. This is really troublesome for the battery can last for three hours. And I have to use it while working. I guess its the laptop AC adapter has got broken. As to the exact problem, I am not sure about it unless I have detailed check. Although most of the failures caused by power adapter damage, sometimes the cause relies on the motherboard. If so, its a big expense to have a replacement of the mother board. And its really dedicated and expensive. However, certain knowledge of the laptop Compaq 402018-001 AC Adapter is helpful when you happened to this situation.

Take this Dell 9T215 NADP-90KB AC Adapter for example, if you are interested in the electronics, you can solve this problem by yourself. At the meanwhile, you can save a certain amount cost. And here through the following case, I will show you how to examine the problem.

This laptop with an Gateway ADP-65HB AC Adapter is out of work. I have to plug it again and again. The notebook computer can work. But after several weeks, the adapter indicator has no reaction. When the battery is depleted, the computer cant boot and has response. After analysis, the battery can work without any problems. Then the focus is on the adapter. I suspect that there might be something wrong with the adapter lines inside. Usually, a multimeter can help you finish this step. To my surprise, the output voltage is normal; it seems that the Gateway ADP-65HB BB AC Adapter is within no problem. This indicates that the problem must be on the laptop itself. As I carefully disassembled the notebook laptop, there is a resistance in the interface. According to circuit analysis, this resistance is an insurance resistance. Because of this resistance appears not closely welded, the current can not go through to the motherboard. Then the problem has been solved within a quarter.

In fact, there are some cases that can be solved by ourselves. Consequently, if we acquire some repair and check knowledge about the laptop, there is no need to worry about it when we come across these situations.
