I've been noticing that my Macbook won't even break the 3 hour mark for battery life... and I'm thinking of doing an exchange through apple care... I've had it for about 5 weeks now.... I just want to know if you've exchanged yours due to battery issues? 1) did you do it at the store or over the phone? 2) what did you say... how did you present your problem? 3) how willing was apple to replace your entire computer rather than just give you a new battery? any info would be great! Thanks Macrumors community!!! you guys are awesome!
