i called apple tonight. i explained to them that i think i have a dead pixel. he suggested i go to the apple store to have a genuis look at it. then i told him the alignment on the powerbook is not correct, which is true. i had this same problem with the 12" i bought a couple of months ago and had to return it for an exchange. the manager at the store even told me it was a known issue and he had no problem exchanging it with no restocking fee. the applecare guy told me again to take it to a genuis at the local apple store. i told him i would do so.
i went to the apple store after i ended the call and believe it or not, the same manager who exchanged my 12" a couple of months ago for the alignment problem. i introduced myself and explained the situation and commented about how he helped me last time. he made the process very simple. he basically had a genius look at it, type in some notes and created a case #, and told me to call apple back for an exchange.
in the end, i will call apple tomorrow (they are closed now) and will have them send me a replacement. i would have done an exchange in the store but mine is a BTO with the 7200rpm drive.
i will let you guys know what happens. thanks for the insight.
