The other night, around 2am, I installed the latest QuickTime Update and the newly released iTunes 8. After they installed, my MBP prompted me to restart, so I clicked on the Restart Now button. Then, NOTHING. Nothing. I pressed the power button long, then nothing but the sleep light on. No power up chime, no hard drive whirl. NOTHING. Brought it to Power Mac the following morning and though I am thankful my data's intact, my logic board is gone. The folks at PMC kept asking if there was a firmware update I installed, and I said no, only QT and iTunes 8. Several minutes later, my friend informed me Apple released a firmware update for MBP's via Software Update just then. Is it possible the software updates for QT and iTunes caused my Mother Board to go kaput PRIOR to the Firmware Upgrade???? Just guessing. Could be coincidental but I really wish right now I didn't install the updates. WORST PART: My warranty expired a month ago. !%@^@&*#^*$#&#^@%$!!!!!!!
