Sorry for your trouble...but please try to remember that there is *NO* manufacturer, nor has there ever been, who has never sold a computer hardware product that has had at least some bad units. Apple's defect rate is lower, and their customer service scores higher, than most anyone. But they also use many industry standard components. It isn't possible with the current state of technology and manufacturing, for them to offer you a completely zero percent chance of product defect.
They should be fine about fixing it for you. I'm sure they'd be happy to look at yours, too, although if you can't see a problem, I doubt in this case that they could either. Good luck!
