Hi, My Macbook Air notebook (2011 13 inch version) last week suddenly turned off (while it was connected to a wall outlet) and would not power on, no matter how many times I pressed on the power button. Fortunately, the next day, the notebook powered on. I also wanted to add that the notebook has been sent to Apple for repair, for either replacement of the logic board and/or the cable connector that is attached to the battery and logic board. I would appreciate any feedback from members who have experienced a similar situation where their notebook suddenly turned off while attached to a wall outlet. Thanks!
