Ouch, the poor thing. Our first A4000 mobo died because of that affliction (I still weep over the loss). Thankfully, our newer mobo had seen the battery being taken out before it was sold to us. There was no visible damage to the board, and we had it taken care of, just in case, as according to the advice of the lovely folk here.
I hope no lasting damage has been made to your board, dEViAN.
