I just opened the box of my brand new white macbook, 2.4ghz, 4gb ram, max hard drive (250GB?). I turned on the power and immediately there was a fast clicking noise as the welcome video played. After the sound stopped, so did the clicking noise. As I went into the registration, I got my internet to work and then went to register my product. When I tried to type in my email address (which contained a "5"), I was unable to proceed because the 5 key didn't do anything. Is there any way to fix this, or do I have to call apple support and get a new macbook?
