I have a Macnook Pro 13" Mid 2010 and this evening my wife was on it and the track pad split in half and began to expand. I quickly unplugged and did an hard shut down. I unscrewed the bottom and to took the battery out as quickly as possible before any other damage happen. A peace of the battery bracket that was held down with a screw was broken. the Macbook was working just fine so i believe i saved it before it possibility exploded. Has anyone had something like this happen before?
