Do you have a problem with the power connector on your laptop and want to know how to fix it yourself? This step-by-step power connector replacement guide will be very helpful for you. The guide will explain how to resolder a loose power connector or replace the connector if it’s broken.
Warning! This guide is only for experienced people, who know how to solder. If you are not sure, do not try it at home. You can damage the motherboard.
In order to replace the power connector, you’ll have to disassemble the laptop and remove the motherboard. You’ll find instructions for the motherboard removal for name brand laptops like Acer, Dell, Compaq, HP, IBM, Toshiba, Sony in these service manuals.
Static electricity can kill your laptop. I recommend wearing an anti-static wrist strap while working with internal parts of your laptop.

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:

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?
