I haev a Dec 2006 17" MacBook pro. I noticed a buldge in the battery and popped it out. Luckilly i did as it proceeded to explode while sitting on the shelf over the next few days. As far as i can tell its still growing. Dont have apple care so talked to Apple and they said i was outside the 2 year replacement-Bad luck. Any body else manage to get a replacement. Thought you guys might like to see it.
