If I leave my Mac idle for some time it may go to sleep as expected. Most time the screen content will show up right away if I move the touchpad pointer or use the keeyboard. At times however the pointer itself moves on the screen but the rest of the screen will stay black for a while (few seconds up to 10-15 seconds)..
What can that be from?
MacBook Pro with Retina display, OS X Mavericks (10.9)
Hey an1980,
Thanks for the question. I believe you may be experiencing the difference between “sleep” and “deep sleep”:
