DC power jack repair
Fixing DC power jack
Fixing a DC power jack on a laptop can be difficult. Not knowing what you are up against is a sure sign that you won?t ever get it back together. However with the proper steps, repairing a DC Jack can be accomplished with little headache.
As step zero, it is important to make sure that you identify a bad DC jack. If a laptop isn?t charging when it?s plugged in combined with a very loose power jack port usually indicates you have a bad DC jack. I have also seen DC Jacks that are just fine, however when looked inside, you see it has been physically destroyed on the rear end of the jack itself. Each case is mostly different, but you will run across 3 possible scenerios.
1. The DC jack has cold solders and it just needs to be resoldered (the most common).
2. The DC jack has been broken in unseen areas of the jack itself (common diagnosis is the wiggling of the jack with the adapter).
3. There is nothing wrong with the DC Jack and it?s an issue with something else onboard.
