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.

Eddy,
Most likely the connector just loose and has to be re-soldered.
It’s necessary to disassemble the laptop, remove the motherboard and resolder the jack.

I have a question. My laptop connector works provided that I place an item, such as a pen, under the charger plug that goes into my laptop. I don’t know if the connector is loose or simply damaged. Can this be fixed?

Ron,
It’s possible that the laptop will not charge the battery because the “+” wire is not soldered properly.
On some motherboard you have to provide “+” power to BOTH sides of the motherboard. When the power jack is installed, both sides of the motherboard are connected through the copper sleeve inside the “+” hole on the motherboard. Thus, you plug in the power adapter into the jack and both sides of the motherboard gets power.
In your case the power jack is missing and it’s possible that the copper sleeve inside the “+” was damaged, it’s common. Take a look at this guide for more info:
http://www.laptoprepair101.com/laptop/2008/10/28/fortify-damaged-power-jack-connection-in-laptop/
It’s likely, that your guy soldered the “+” wire only to one side of the motherboard and the other side is not powered. That’s why the battery is not charging.
Hope you understand what I’m talking about.

Thanks!
Since the lappy now does not have a DC connector at the back and only 3 wires come out of it, I have cut off the connector from the power supply and hardwired it to the wires coming out of the lappy. It works fine this way but no yellow flashing light to indicate battery is charging. Do I take it that whatever problem I have now is not connected to the way the laptop is now powered?
