hey all - Next weekend I am sending in my 15Al in for the old white spot issue and now I have found another issue. Sometimes when trying to adjust the volume via the PB's F3, F4, and F5 volume keys weird things happen. Sometimes they act like they should (volume increase actually increasing the volume, volume decrease actually yada yada yada). Recently I have noticed that the increase button will actually dcrease the volume by a few bars and then it will work for a couple bars and do the same thing. The decrease button is sometimes exibiting similar weirdness. Has anyone had a problem similar to this? Normally I wouldn't sweat it but in an office, making the music increase by 3-4 bars can really annoy co-workers. Also, Do you think this will dramatically increase the return time on my PB if I have them fix this problem as weel since it is going back to Apple anyway?
