Hello Alexcb & Jeff Junatas,
Thought I'd add my experience to this thread, as we just came back from dropping off my 1'st gen iMac 1.6 (single cpu) at a Apple store, where I had taken in twice previous for problems... I did bring the Extend Warranty letter, documentation on all of the sad history, and the Genius just nodded sadly and said it was too late for the warranty; But that after hooking up to his laptop and running some diagnostic program, pronounced the Logic Board as bad and that he would take care of it at no charge.
So, left with my iMac empty box and a receipt showing $ 0 due, and they would call me when it was ready.
I
don't know what they replaced on my two previous trips before so don't know if it was another Logic board then. And I didn't see any point in discussing the Extended since he said it was expired, BUT was going to fix it at no cost.
I suspect that they are told not to "extend" the warranty on the 1'st gen's; but then replace it at no cost for customer good will. That way, it makes us feel like they are going out of their way to help, just for this one time.
In any case, I'm pleased not to have to pay for a new Logic Board, so no reason really to pursue this any further. Now I just hope this one is stable.
Good luck, and do post back and let us all know if you have success.
Respectfully,
B. Gallagher
