I have a new white macbook 2.4GHz 160GB. does anyone know the functions of the two lights next to the webcam? when I have iphoto open, the right light fluoresces green, but I have yet to see the left light turn on. does anyone know what color it's supposed to be/when it should turn on/what function it serves? just want to make sure my mac is in working order. let me know, thanks!
