I just had a quick question that I was hoping forum members would be able to help me with. I have a Core Duo MBP with the old style power brick. The brick gets really hot and a couple times I've had the problem where the LED on the end doesn't show the right charge status. If I take this in to the Apple Store will they replace it for me? Do I need to make an appointment with the Genius Bar or will I just be able to walk up and get help with this non-technical problem? FYI, I'd be going to either the SoHo or 14th St store and they will obviously be crowded.
