Basically what is said above. Within the last month my Macbook (purchased in August 2006) has been randomly shutting down. It has been running slow (despite the 2 gigs of RAM I just upgraded to) and tonight my iSight is no longer functional. It has never been exposed to heat and never had significant water damage. Three days ago a Sierra Mist lid (damn pepsi) had a problem with it and leaked in my purse where my macbook was, but the case was only damp and it worked fine immediately after, including iSight. I turned it on to use it as a mirror ( i love being a girl) and it flicked black, I tapped it a little and it became a yellow tone but it showed my image, then it went black. I KNOW Sierra Mist didn't reach that (it only got on the case a little, it wasn't even damp and didn't enter any ports, I checked all of them and they were all as dirty and dusty as before). Anyway, all of that said, I have an appointment at a Genius bar. Any ideas of what I should be expecting?
