Excellent instructions. I dismantled my 2006 macbook, and my optical drive, to retrieve an installation disk that mysteriously wasn't booting. Funnily enough, the drive was empty. Ha, ha. Then I noticed the disk on the mantelpiece... . However, the whole experience was educational and kinda fun.
Did I reassemble it? No: almost everything, especially the software was on its last legs, so I succumbed to my wife's persistent demands to put it out of its misery. Lovely machine though. They don't make 'em like that anymore. Sob.
