That happened the day after I bought my iMac i5 (week #51) from Best Buy. I used the power button to bring it to sleep mode, and after about 2 minutes, I tried to wake it up using the power button (instead of KB/mouse). I could hear the HD spinning sound (it did come back from sleep), but the screen remained dark, and in the end, I could only powered it off by holding the power button.
The problem has happened only once so far (I bought it on Jan 1st) and I couldn't reproduce it.
Any suggestions? Should I do something about it? Exchange for a new one? Or wait until it happens again?
