@ Laura,
First of all, I would test the laptop with another AC adapter. It’s possible that your adapter not working properly under load. It might output correct voltage when not connected to the laptop but as soon as you plug it into the laptop it stops working as it should. Try another adapter.
If another adapter doesn’t fix the problem, most likely there is something wrong with the motherboard.

Hello, I have a problem with the way my laptop is charging. I checked already the AC cable and the battery themselves and they are fine, the problem is that if I plug in the laptop with the battery on it seems that everything is ok, the light is on and the icon shows that is charging, but is not really working because the battery is going low, and if I take off the battery and leave the laptop only with the AC cable, it doesn’t charge and it doesn’t work. Also when I checked on the device manager and it doesn’t show the three items that it has to have, it is missing the Microsoft composite battery.
Please help me out this is very unusual.

Ken,
Did you test the AC adapter? Maybe your problem is not related to the DC jack? Find a voltmeter and test voltage on the adapter plug. While testing the voltage, try moving the power cord. If power cuts off when you move the cord, apparently there is damaged wire inside. If that’s the case, you’ll have to replace the adapter.

I have a Gateway MX6426 that was not charging/ powering on with the AC adapter. I replaced the moterhboard b/c I thought that would be easier than replacing the jack. The computer works, well….but It did not solve the problem. The computer powers on/charges only if I apply firm pressure to the ac adapter plug while plugged into the laptop. Obviously, this is not ideal. Any suggestions?

dawn,
There is no way I can tell what is wrong without looking at the laptop.
Take a closer look at the DC jack again. Make sure it’s soldered properly. Make sure you didn’t short any trances. Check continuity with a multimeter.
