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.

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?

Ron,
There is no special battery cable. The battery gets charge from the motherboard.
You’ll have to disassemble the laptop and take a closer look at the place where those wires are soldered. Test it with a voltmeter.
And stop shorting blue and red wires, you can kill the motherboard.

Hi,
I live in one of these outposts where it was impossible to find a DC connector that fits my Compaq N610C. The guy from I bought it used, offered to solder three wires and have them come out of the hole at the back! He has since gone overseas and I can’t contact him. BTW the wires are red, green and blue. I put the red to +ve and green to -ve. The laptop powers up and I can work on the AC PSU, but the blue floats now. If I connect the blue to the red it archs and the lappy shuts down!
My question.
How do I figure out which wires to use to charge the battery?
Thanks!

I have unsoldered a broken connector on a acer aspire 9300,the pins were broken off in the holes (my daughter dropped it) and the now empty holes on the motherboard are quite messy. one is even almost connected to the next.Everything is really close together and I cant see any inner sleeves to the holes.
Anyway I have tried soldering a new connector in twice but both times I get a short circuit.
Is there a way of soldering wires to the board through the holes to the underside of the board ?
It works on battery but the battery wont charge.

marcus,
If you can make a guide, I will gladly publish it on this site. Let me know when you are ready.

Dude I couldnt un solder it so what i did was tore he metal plate off and then it was easier and safer to take off the board cause then each metal comes out piece by piece, I should put a better guide out for people who are not pro techs yet.

Nate,
Unfortunately I cannot help you without looking at the laptop. It’s possible that you have to resolder the jack or maybe you have a dead motherboard.
If the motherboard gets power through the jack but the laptop appears to be dead, probably there is a problem with the motherboard.

Hi guys… Maybe someone can answer this. I ordered a new power jack connector, and took the old broken one out, then soldered the new one back in. But, I am still not getting anything to power up. Even though, I know I need a new power adapter, I know I am getting power through it, but, when I am plugged into the DC power jack (laptop)… nothing still comes on. I was reading through some of the other posts. I didn’t clean the new post/tabs before soldering them in place. Should I have done that, and can anyone give me a suggestion on what else I should check, before I order a new power connector board?
I just unfortunitly purchased another used laptop, from a repair shop, before I came across this site. I still plan to keep my old Compaq Presario M2000 though, especially now that I found I could order another Power Connector Board off Ebay.

[...] a case of power connector (power jack) failure either resolder/replace the power jack or replace the whole power connector [...]

Thanks Laptop Tech for the response. The laptop powers up even without the battery. And even if I wiggle while it is on, it does not turn off. I bought another adapter and I don’t know how I should use the laptop, so it won’t go bad. The adapter is working ok so far.
