Hello, I just switched to a rMPB coming from a regular MBP (2011) and I'm experiencing a little "problem" -both systems are on mountain lion-. With the old macbook I used to connect the thunderbolt display and, when I woke the laptop from sleep mode with the lid closed, I was then able to open it without the display turning on (wich is exactly what I want). With the rMBP the display wakes up no matter what, and the only way to keep it turned off seems to be by closing the lid, and keeping it closed. Any idea of why and/or how to fix this? Before you say "just use it with the lid closed": it runs too hot to do that when you use certain softwares, I'd really prefer not to. And powering both the displays at the same time when not needed is a total waste of hardware resources. Hope I was clear enough, english is not my primary language.
