Was I suppose to sand the light green or dark green part to expose the copper and have new traces to solder the new dc powerjack? I had trouble de soldering the old dc powerjack and got to impatient and damaged the traces in the process. The other side is undamaged and those three traces are the only problem with this motherboard. How can I make new traces to solder in the new dc jack in and power up my computer? I was also watching this youtube vid as an example. Ill post more pics if needed.

Fixed your link for you.. It's the light green you have to scrape off and you still can a bit further back. The main thing is to use wire/solder to attach traces to the pins. Please be more careful than the video shows tho.. Every board is different and the one he was using to demonstrate seems to have a good thick copper base (most don't).

My knowledge of this is limited to a very few DIY projects, but if I'm not entirely mistaken, the pins each connect to their own individual traces here, right? The top left pin to the trace above/to its left, the top right pin to the trace to its left, and the bottom pin to the trace below. I see you've scraped the coating off to the right of the left pin - if my assumptions are correct, connecting the left pin to this would cause a major short circuit. Please, could someone a bit more knowledgeable than me confirm or deny this?

How I believe they should connect (inside the red lines):

From watching the YouTube video, you could probably do with uncovering some more of the trace too.

Thanks for the help mates. People in other boards keep telling me to just buy a new motherboard but I believe this can be fixed by doing it carefully. Before going any further I would like to get more feed back on how to accomplish this and doing it right.

Try as Valantar suggested. My experience is that some Laptop MB have trace in between layers. If that is the case you have your work cut out for you.

Many PCBs have multiple layers. A typical configuration would have the signal layers on the outside with the power layer between. It would be a good idea to look at a detailed schematic to avoid any problems. Most of the time, you can't tell how many layers the PCB has by looking at it.

Then again, if you have nothing to lose by attempting a repair, why not? Be careful and try not cause any further damage to adjacent components.

Put solder rings over it, the solder is probably on the top and bottom of the PCB. Nothing to lose............
