I have a 15" Revision D High-End MBP, that I have a few questions about... 1. I run this through an external display. I have no desire for an extended desktop or mirroring, so I run it with the case closed. That's the only way I've been able to figure out how to run just the external monitor. Is there another way I'm missing? 2. Is running it with the case closed bad? Sure seems to get warm. I'm wondering if heat is supposed to be released through the keyboard. 3. What are the proper steps to take when I want to disconnect the MBP from my external display, FW drives, USB connections, etc? Is shut down and unplug the preferred option? Thanks.
