Obviously it is a Dell XPS M140 with the dreaded AC plug issue (what a biotch!) Doing a little searching online comes up with many posts, but this is the best forum I found so I want to share and see if we can figure this out together.
Has anyone successfully resoldered the AC plug? I have the motherboard out but I can't see any obvious burnt or broken solder joints.
Cold solder joints are not always visible. Now that you have the board out. Apply a small amount of flux on all the pins on the power jack. Then retouch each joint with a low wattage iron. My suspicions tell me there's more wrong then the power jack.
