MacBookPro Battery Explosion
last week, sat down at my MacBookPro in the morning, and noticed the machine was no longer sitting level on my desk. Flipped it over, and realized the battery had expanded severely enough to bend the metal casing.
Luckily the battery was still in warranty (11 months old), and Apple quickly sent me a replacement which arrived the next day.
The Apple customer support dude said it was overheating, and rare to happen. Just glad it didn't frack up my laptop.
