First, I searched for a solution, but I don't have an external mouse or keyboard at the moment. How do I shut the lid on my MBP or turn my laptop screen off when connected to another source? i.e. 46" Sony TV? I just hate to let my screen burn while a 2 hour movie is going, and I could just lower the brightness to 0, but I just want to close the lid. Everything I have read, you have to have an external mouse hooked up to wake the machine after closing the lid. Really? Apple didn't think of this use, of all things?
