I can't speak for this model, but the power jack is typically soldered
directly to the board, and all-too-frequently, surface-soldered
(soldered on the same side as the component), and very difficult to do
by yourself by hand. If it's on a sub-assembly, you might be better
served by replacing the sub-board, but looking at the external pics, I
have my doubts that this is the case--it would require a whole logic
board replacement.... aha. And I found this:

and the opposite side:

It looks like my suspicions are confirmed. On this site, the board
sells for 129£ (not dollars). It shan't be an easy job. I have had a
couple laptops lose either sound or power in this way--I always had to
replace the boards. In my experience, Dells have been fairly easy to
open and look at, so that part I wouldn't see as a problem--but
resoldering that plug...
