If it happens on a 17" it's game-over...
...but the user won't easily notice until it burst into flames.
{Puts on Apple fanboy mask}I had that happen to my 2006 MBP battery last year. It was on the floor and hissed and popped and shut off. I flipped it over and the battery was bulging. I ran down to the Apple store because I use it for work and had to buy one. They would not/did not cover it (or at least the person I talked to did not)
Apple does not make bad batteries
I think this wont be an issue with the new unibody 17" MBP's because Apple tested each one 3 times before they left the factory, thats why most come with 3 cycles already.
As I was packing up my computer this morning, I noticed something horrible...
...my MBP's battery was bulging.
I thought that was a 2006-2007 thing, but bulging batteries in 2009?
Now, will Apple replace this battery for me?
This part is true, because Apple does not make batteries.
My MBP battery might be in the early stages of this. The outside layer is starting to separate a bit.
don't you mean...apple doesn't make computers
Apple just replaced my three year old MBP battery today after it was bulging. (The battery was already replaced once when a few months old.) They didn't give me a hard time; I was impressed since my computer is long out of warranty.
