A APM and GPT riddle

[sjs]

grasping at straws here but can only think of one causal factor, highly improbably as it is.

my macbook has some kind of PMU bug i think... If the macbook is running from battery and you plug in a FW drive (powered) the machine instantly turns off. if it sleeps and gets unplugged from mains power while a FW drive is plugged in, it won't wake up. Reseting the PMU as described by apple solves, temporarily #1 until #2 takes place.

i think they will have to replace my mobo..

how this magically transforms a partition seems unrelated and impossible to me, i know...

i only bring it up because this mac is already acting funny...
