2012 MacBook Pro Powers on By Itself on Rough Roads

The difference here is that I might reasonably be expected to be taking my laptop with me on road trips which could get bumpy. I.E. this is not that much of an extreme case.

OP might have a faulty unit. I never experience this with my Macbook Air, which has similar design of the power key as the new Macbook Pro.

I think it shouldn't wake up when the lid is closed. Am I missing a point?

I keep hearing things like this about the Retina MBPro. Dangit I WANT one, but my spidey sense keeps insisting that this is first round, early adopter technology and that I'll be MUCH happier if I hang onto my early 2008 17" MBPro for another few months or maybe a year until the next laptop line bump from Apple.
