zapped iPAQ?

[afalla]

Any advise?
I (dumb me) used the wrong car power adapter on my iPAQ and noticed what I did a little too late....I thought that I just blew out the fuse on the charger, but when I came home and placed it on the cradle I noticed that the battery light never came on and the front panel started overheating.....I thought it might be a bad battery so I swapped it with a spare I had, but I got the same result. The unit works fine, but it just won't charge and now the battery is almost drained out....any advise????

thanks
