I had noticed over the past few weeks that my trackpad button seemed to be somewhat broken. It worked still but it was very easy to press and didn't click and on the right side, didn't press down. I turned over the computer today and noticed that the battery is bulging out on the side where the battery lock screw is. I took the battery out and now the track pad button works like it should. I'll leave it out till I can get a new one this weekend. Anyone have any luck having Apple replacing the battery when this happens? Battery has 197 cycles and is at 96% health.
