Two month old 1.83 Macbook started off with slight mooing, which I can live with, gradually developed slight yellow stain to left side of trackpad button, which I can live with, and LAST WEEK IT BEGAN TO SPONTANEUOSLY SHUT DOWN ABOUT 30 TIMES A DAY, WHICH I OBVIOUSLY CANNOT LIVE WITH!!! As you can imagine, this is very frustrating. I am presently trying to arrange to have the replacement logic board sent to my local repair shop before taking the Macbook in to minimize the turn around time.
