I've a MacBook Pro with Retina display. running 10.8.2 (and Win7 x64, via Bootcamp).
I somtimes experience trouble coming out of sleep with no external display connected, if the MacBook was connected to an external display when I sent it to sleep and the integrated display's brightness was turned all the way down. Basically, the MacBook's integrated display won't light up. I then need to hold down the power button until the machine powers off, and start it up again. Only then will the display come on, and the machine start normally.
I've been observing this with both an external Thunderbolt Display, and a TV connected through the HDMI port. I don't think this is a Mac OS issue, as I've seen similar behavior on this same machine, running Windows, under Bootcamp.
An example scenario: I'll be using the Thunderbolt Display, or watching a movie on my TV, with the integrated display's brightness turned all the way down, and then, while the display is still connected, I will close the lid - The machine will go to sleep. I will then come the next day, and while the computer is asleep, disconnect the external display, and open the lid. The MacBook's integrated display will not light up, the brightness keys will not respond, and I will need to force-shutdown the machine, and start it again - it will then start up, and usually fall back to the lowest display resolution setting (even though I always use much higher resolutions on both the integrated and external displays).
I'm guessing this is happening because the computer is expecting the external display that was connected to it, during its last operation, to still be available, and when it's not - it panics!
Also, I had times where this happened, and a force-shutdown would not do the trick. I had to actually connect back to the external display, wait for the machine to start normally, take the integrated display's brightness back up, and disconnect the external display. The machine would then resume normal operation, and I would be able to disconnect the external display and work on the integrated display.
Has anyone else experienced this, or anything similar?
