I have a Dell xps m140 (about 3.5 years old) that has been having power issues. The jack was loose and the computer wouldn't recognize the power adapter, which led to the unfortunate circumstance of the battery being unable to charge and thus requiring constant power. From what I read on the webz this isn't really at all uncommon w/ the dells, and the most apparent problem was the dc power jack.

So I went ahead and replaced that and although now at least the plug is a secure fit and thus I don't have to worry about it coming loose all the time, it still won't recognize or charge the battery. This is still the stock dell power adapter. I'm now thinking maybe the power adapter or battery being the issue, but both really seem rather strange for the symptoms (I am greeted upon POST by a message indicating the power adapter is not recognized). Any similar experiences or ideas?

have you tried removing the battery pack out of your laptop and leave the power adaptor connected? If the laptop turns on without the battery pack and the power plugged then it could be the battery not recongnising it or like you said could be the adaptor

Sounds like you may have an issue with a solder connection as well on the board... Ebay has lots of power jacks for all laptops if so...

That's what I fixed. Soldered on a new jack. I'm gonna get a new ac adapter and see if that remedies it.
