My 2011 MBA worked last night without a probem and I charged it for the first time on a MB charger mybe this is the reason why. This morning it wouldnt turn on. I saw the sign in page (where you enter your password when the screensaver goes on) Went to get a coffee and Nothing! when I plug in the magsafe The Led is green. I tried the following: Press the power button for 10 seconds Tried 3 differents magsave adapters Reset the pram (did nothing when I pressed the buttons) reset SMC (Pressed the button no reaction) Took the battery and the Ram out of the MBA and reinstalled them. I´m working on a boat at the moment where we travel a lot and I called all the apple stores in the area but they need 1 to 2 weeks to look at it, so this is not aan option. However i can get all the parts no prob. thanks a million!!!
