Answer to: Water Damage, Logic Board appears fine...no Boot?Well, I was looking forward to getting the Multimeter out, but replacing the keyboard was the answer (as Louis points out on YouTube, it is a primary suspect). Interesting for someone later, maybe: I had to drill out 10 of the PH000 screws holding down the keyboard backing metal sheet. No big deal. Ordered this keyboard from amazon, and it functionally works, but the screw holes don't line up in 10 locations,so some of keys are not rigid enough. http://www.amazon.com/gp/product/B0065UZ...
