I had a very strange thing happen with my #macbook on a flight. When I plug in the airplane power, the light on the charger turns green and appears to be charging. But the laptop screen immediately goes black and it won't wake up while plugged in. I can't use it plugged in. If I unplug, it works fine. Very weird.
@paco could be the brightness is set to nothing when plugged in. Happened to me once - took me a while to figure out what was going on.
