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.

Last night I've open my laptop to see if I can do enything with this AC plug. Everythinlg looks OK but You can never tell only by looking on it. I'm wondering if its such a common problem why there's no information on official Dell website? or maybe there is?

I saw a thread somewhere that a Dell Tech asked a few questions to someone having problems then decided that plug was broken and the motherboard should be replaced...they weren't very sorry for the obviously major problem with quality control.
