OK, here's a weird one. I was playing with my iMac (10.6.8) and put it to sleep manually. Then I tried to wake it and it wouldn't wake. Huh? So I pressed the power button on the back to restart it. Nothing. Pressed it again. Nothing. Aargh. Probably the power supply or the logic board. So I take it in, and show the repair folks. Yep, won't start up. Nothing at all. No screen, no chime, no fan or disk clicks. Nothing.
A few days later, they get a chance to look at it in the lab, and it boots right up. No problem. Checked the memory and SMART status on the disk. No problem.
Whaaaa?
We had a lighting storm a few days before, and the power flickered, but that doesn't happen infrequently. It is not on a UPS or even on a surge protector (my bad). I am told that the power supply can "self protect" by going into a mode that it doesn't come out of for many hours. Is that true? Of course, there was nothing to protect it from when it stopped working.
Anyone heard of this kind of thing before? I've been using Macs for decades, and have several, but I've never run into this before.
