Assuming you ordered a laptop on Apple's online store, and you receive a machine with 3 dead pixels. I know that according to the rules, Apple will not replace the machine. But, hypotheticaly speaking, can you claim that there is something else wrong with the machine and try to exchange it at the Apple retail store before 10 days have passed? For example, claim that you are experiencing problems with the superdrive or that the screen blinks once in a while or whatever. I would just like to know what is the exchange procedure at the Apple store. Besides, is it at all possible to replace not a BTO faulty machine that was purchased at the online store at the retail store?
