Hi all, I have one of the faulty MB's, it only exhibits shutdown issues on cold boot, however at no other time.
This morning I tried holding down the power button with the AC and battery plugged in, the MB made a different beep from that of PRAM reset.
What does this beep mean?. It then started successfully.
So it's a morning routine to zap the PMU and PRAM!! Occasionally that helps. (I need it for work for the next week so i pray it continues to eventually start before i can return it). Only 15 attempts this morning!
I want to smash it when it won't start

and pat it when it's running!
