I may have just discovered the first problem with the MacBook Pros that Apple just started shipping.
It's more of an annoyance, rather than a problem, but it's one I don't think Apple is capable of fixing (at least with this revision). Apple made the decision to make the new power connector have a magnetic attachment -- the magnet is on the side of the MacBook Pro where the headphone jack and the audio in is on. When the MacBook Pro is plugged in with the MagSafe connector attached, all you can hear is the quiet hum of the fans inside. However, if you detach the MagSafe connector, you will encounter a high pitched buzzing noise very similar to the noise found on the first generation iPod minis. Depending on how much ambient noise is in the area and how sensitive your ears are, you may not notice it.
you mean... while listening with headphones without the adapter in you hear a buzzing?
Nope, it's like a high pitched static hum in the left side, and you don't need to have headphones plugged in.
