ok day 3 of new powerbook 17" 1) the fan noise is enormous. seems to run about 25-40% of the time. is this normal? pb is just sitting on a table in a very cool room. 2) one stuck (dead?) red pixel. am i just screwed? 3) iChat av doesn't work (iSight camera itself seems ok, just can't connect to anybody....) ADSL speed is way, way slower than it was on my windows system. I've got airport extreme so that shud be faster than my internet connection....do i have the base station set up wrong?
