Hi there, can i start out by saying that im new to apple, from the experience i've had with my macbook i'll never be returning to the dark side! Its been a bit of a transition but im learning... slowly Last week my air developed a few issues, mainly a very noisy fan (which i can deal with) but more pressingly some other issues 1. No Sound! No sound output what so ever, the keyboard button won't adjust the volume level at all, it also has a little 'no entry' like logo at the bottom. I've taken a photo of this http://i155.photobucket.com/albums/s320/ashleyspencerbest/DSC_0022-6.jpg 2. No keyboard lights the keyboard lights are not working, when i try to adjust them i am greeted with the same no entry style logo on the pop up icon 3. Bad video Trying to watch youtube and other video sites, videos stick and pause themselves the only way to continue playing is to skip a couple of seconds. Any ideas on what i've done or how i can remedy the issues?
