Trickster

I have an older laptop Dell Lattitude Intel Inside 3.8 GB, 128 MB, 233 MhH that got dropped by accident and the Space Key came off.

A computer guy told me that getting the thing repaired would cost more than a hundred bucks, which I don't have to spare right now as first I have to pay off my credit card statement after last month's party binge.

The other night, after a few ice beers, I decided to try fixing it myself but made it worse after glueing the space key back with Krazy Glue for it became stuck down to the keyboard. I unstuck it with an envelope opener but now when you try to put the space bar into place and push down on it, nothing happens (i.e. the space doesn't go).
Everything else works on the computer but the space bar.

The question I have is should I just trash the laptop?
I was going to donate it but don't know if it's worth the pain.
My question: Do I trash it or donate it or any other idea?
