when I opened up my MacBook this morning. At one side it was completely 'swollen' at the left side of the keyboard and it wiggled because the bottom side was also swollen. When I opened the MBA is saw the culprit: the battery had some kind of internal leaking (?) which changed its shape and therefor the shape of the MBA enclosure. It's a MBA from one of the first revision I bought it in 2008. I'm very disappointed because I can not use it anymore, anyone else ever had a similar failure?
