My wife was using her mid2009 13" MacBook Pro when her dog jumped over her, knocking over a "nearly empty" coffee cup. She claimed that only a small amount of coffee (not decaf, black) hit the top deck to the left of the trackpad. But now the 1, q, a, z, vol+, vol-, and delete keys are non-responsive. The key feel is fine. What is the most likely damage? What is the most likely remedy? The life of that dog may be hanging in the balance.
