My new MacBook is totally flawless... no dead pixels, no case warping, no whine or moo. BUT the MagSafe charger makes a very weird high frequency whine. It's definitely NOT the MacBook, it's the charger. It's almost a staticy sound. Anyone else with this issue? I'm going to call Apple tomorrow. I don't want a new MacBook, though. I'm hoping they'll just exchange the charger.
