OK the situation is as follows: I bought a brand new MBP 13" last week. I was planning to sell my old white macbook (from Jan 2007), but yesterday when i started to put in selling shape (i already have a buyer) i noticed that the battery has started to deform. It's like blowed up from the middle. The battery works still fine, but the deforming has caused a problem. The trackpad won't work because the battery is pushing the button under the battery (the grey circular one) and the battery deforms the case a little bit. I'm planning to call apple this afternoon about the battery. Any wishes that they would change the battery for free? I know it's almost 2,5years old, but I think that can't be normal for a battery...it can be a healthy hazard if it decides to blow up? So any thought about my situation?
