This is my solution and it works on my MacBook Air 11” (1) Disconnect the battery, plug in, do the resetting SMC (2) Turn on. (Test unplug, it still turn off) (3) Plug in. (Auto turn on) and normally shut down the mac (4) Do the resetting PRAM (Option + Command + P + R after pressing power button. Release after second chime) (5) Turn on. Unplug. IT WORKS!

I have this same problem too!!!. How did you fix it?
