Anybody having issues with the power cord not seating properly to their mac mini? I push really hard and the the light will come on and by the time i place the mac back onto the shelf it goes out. I have to wiggle it and finally i just have to be very careful and it will finally work, but this is unacceptable. I have a BTO so going to the Apple Store to see what they can do. i7 2.6ghz fusion drive
