On my left palm rest of my powerbook i have notice black little dots. I tried to wipe it off with just water but it didnt come out. On inspection i notice theres a crack in the aluminum. I bought this powerbook last october and i think it comes with 1 year warrenty, correct me if im wrong. I didnt buy applecare. Well before i make my 60mile trip to the applestore if there any hope for me?
