The question is: When you unplug the AC power from the computer while it is connected, closed, to the display, does the computer immediately go to sleep? I know it does this on older models like the one I have because there wasn't enough power from the battery to run the DVI out. It'd be real nice to know if Thunderbolt didn't require insta-sleep when not connected to AC power. I ask because my cat recently discovered he can unplug the MagSafe connection on my aging MBP (and thereby cause me a great deal of attention-generating consternation) with a good solid paw-whack a few inches down the cord. I'd love to know if the newer model I'm about to upgrade to has this same problem. It's actually easier to solve on the newer models since all the ports are on the same side and I can just basically put it in my desk backwards so he can't get to it, but I'd love to know before I rearrange everything.
