I think you can fix it.
I had the same thing happen. I loaned my computer out, someone tripped over the cord and broke the female side of the charging mechanism inside the laptop. No charge light unless it was pushed in hard or tweaked just so. With nothing to lose, as I thought it was gonna die anyway, I took apart the laptop and the whole
casing is plastic.
The charger sits in a plastic holding case inside that laptop, and the holding case was snapped on one side. Can't use superglue (heat) I could have soldered a whole new jack piece but I've never soldered before and the laptop was just a year old! I'd thought I'd fry it trying to solder! One drip in the wrong place and it's all over.
Long story short (er) I used pencil erasers. Shaved just the right thickness with a razor, wedged it this way and that until it was solid. Still holds to today
There's lots of info here
. Maybe it'll help?
It's not an uncommon issue, apparently.
They have the new jack parts at Radio Shack, lol. Regular stock. If you want to weld in your own, new. Then it's super solid. It's a small space to work in tho, a 1 inch space inside the corner of the laptop. One side was bust on mine, so the eraser parts worked well for me. It's not a difficult fix. Maybe while your in there you can fix the keyboard too. Might just be easier than you think!
