    I was wondering if anybody knew if there's like a physical switch or sensor that let's the MacBook Pro know when its in clamshell mode. I know you need an external keyboard and/or mouse and close the lid as soon as you boot up. I assume there's something that lets the machine know that the lid is closed. The reason I ask is because since my MacBook Pro fell and broke its screen, I'm planning on buying an external display to use. Currently, I have the MBP hooked up to my TV via VGA and keeping the lid closed with only a mouse hooked up. I'm planning on going headless, and I don't want the MBP to think its lid is closed and display in spanning mode. I already opened up the machine to fix the casing and to look at the display, but I didn't notice anything that would tell the machine that the lid is closed.

    Or better yet, is there a way to force the MacBook Pro to use the external display and display in mirror mode only at boot up?

    Part of the hinge as in part of the lid and rest of the display? It didn't look easy to get into that part when I was dissecting the lid.
