Just received my macbook pro retina with 2.7/16gb/256gb and had an absolute ball using it.
I turned it off now im trying to turn it back on and it wont start up. i plugged the charger in but the charger doesnt light up or anything.
Quite a few have reported this problem. Several have found that unplugging the battery and plugging it back in seems to solve it: Here's another thread in this forum with people with the same problem, and a few who have got things working with the battery unplug solution: https://discussions.apple.com/message/21571912#21571912
