I thought it was just the notebooks, but yesterday's work proved to me that it happens to iMac's as well.
At first, the customer took it to the "Genius Bar" and they told him some caps pn the logic board was fried. For me, that's gives me the green light to experiment. (After all, what more damage could you do?) I did just that. Opened it up and the caps were all intact. I replaced stupid things like the ram and the 3.6v lithium battery. of course, I have endless installation disks 3 didn't work, the 4th did. The givaway was when I got into Target. That tells me the logic board is functioning in that sense. So I ram disk utility from my Mac Pro (After all, what's the difference between running the OS off disk and the os an external HDD?) BINGO. popped in a new SATA and the bitch is rolling.
Now, I've repaired over 50 MacBooks. Many of times, I've seen a failing drive crash the whole system and prevent it to get past the chime... but never an iMac. WTF is the deal with Macs and crashed hard drives preventing the whole system to do anything?
Nobody knows, do they?
It's just one of those Mac mysteries.
