I bought a Macbook Pro around 4 years ago. While under warranty, the macbook pro battery just bulged and apple replaced it. Around 2 weeks back I had my macbook on my lap and was working on it. Felt a bulge with a thud sound. Guess what? It has happened again. Apple says this is very normal. Wanted to find out if this is something expected or am I just one of those guys out of luck and well conned!!
I got a diagnostics done on the macbook pro from the apple service center and they told me there is nothing wrong with the motherboard. My worry is in the last 3 years this battery bulge issue has happened twice.
I am still using Os X 10.4.11 which pretty much serves my purpose in the classroom.
Currently I dont want to risk buying another battery lest that also fail like this one.
