My 2007 MBP's battery simply dies even though it says there's 2.0hrs remaining. I took the battery out after my laptop turned off abruptly. There was no warning or transition into sleep mode. Look at the two pictures of both sides of the battery. One of them has the backplate lifting about 4mm from the edge. There is a big bump on the edge. I think my Battery is dying. Hoping that my AppleCare will cover it.
