My MacBook (C2D) makes a whining sound when it's running on AC power, but it goes away if I turn on the webcamera. It's quite annoying when working in a quiet environment. Will Apple actually do anything about this? Also, how come Apple have no support e-mail? Telephone support is free for the first 90 days, but after that, if you have a problem, how do you contact them without paying a lot of money? I don't live in a country that has any Apple stores.
