Old iPAQ 3760 with something fried inside?

[TomeQ]

I've got an old COMPAQ iPAQ 3760 from friend. It was working ok, but one day my friend inserted wrong AC adapter cable (5V too but with reversed +/-). And then iPAQ stopped working (battery was empty) and charging too. Friend give it to me. What part may be broken now? It will be very expensive to repair? Thanks.

You could try another battery, but since this costs quite a bit, my recommendation sadly would be to forget it and get a new/used PDA.
