@fun@elly are we talking about the 2006-2007 model with the palmrest that cracks on the edge? those are obvious i wasn't aware the 2009's were fucky, too :/
@Lili I don't think that's possible, unibody was completely re-designed. I've worked on 2008 before, battery was removable from the bottom where you removed the bracket to get to ram slots and the drive, pretty sure layout had changed
