I have a late 2010 13" MBP running Mountain Lion. It's mounted in a Henge Dock, connected to my 23" monitor. Every night I put the MBP to sleep by hitting CMD-OPTION-EJECT on the Apple Bluetooth keyboard. Lately, some mornings, it won't wake back up when I hit a key on the keyboard. The Magic Trackpad won't wake it either. Because it's in the dock it's a pain to remove it, open it, hit the power button, close it and re-dock it. I have found that I can plug a USB mouse into the USB extension cable that the Henge Dock uses and that will wake it up. I'm not sure but I think this started before Mountain Lion came out. Any thoughts why this is happening or an easier way that I can wake it when it does?
