Woo! Okay so a few days ago I noticed my battery wasn’t charging, lame right? so I didn’t think too much of it, and thought I’d just figure it out later. After a couple of days I moved the Macbook to the dining room table and noticed that it was lopsided, I figured I was missing a foot (you know the little rubber feet on the underside), it wasn’t that, I noticed the huge lump on the battery. Turns out it was indeed swollen, or exploded, either way– today I called Applecare on the phone, they said to take it to the Apple Store. So I made an appointment, took it in, and even though it was passed its warranty, the battery shouldn’t have been swollen at its age, so they exchanged it out for me, free of charge. Very awesome.
