Do you still have the original battery? It sounds like it might be in range for pros that would burn up and destroy fun things like the keyboard and blow up like a balloon. My son had that happen and the only way to not pay 100% of the repair was to say the words "and it burned me" while on the phone with their customer support. They had him pay the cost of a new battery ($148) and the rest was fixed at a local apple store. Upon return, they told him that regular maintenance was to replace the battery annually. Yah...mkay.
