    -Pressing the power button brings up the backlight only
    -No Chime
    -No Apple Logo
    -No keyboard backlight
    -No Mouse
    -No peripheries work (External monitor, etc)
    -SMC does work (status change on magsafe light)
    -PRAM is not responsive (again this could be due to not ever being truly shutdown)
    -No Function keys respond
    -If left in this state the device gets very warm and fans rev up

    -Holding the power button down for 3-5 (I have held it for longer too) seconds turns the back light off (presumably the computer as well)
    -does not get warm in this state

    -While in the, assumed, off state (no backlight)
    -Unpluging and plugging back in the magsafe plug will bring the backlight back on

    What I have done:
    -PRAM Reset (Many different timings)
    -SMC Reset
    -Let battery drain down (Then tried all of the above)
    -A million powercycle like things that are truly just random

    I should mention that I am looking for any insight I can get. I am not convinced that my MBA is actually being shutdown, is there a guaranteed method to power this puppy down, or is that just holding the power button down?
