    is there a light on the magsafe charger?



    before exchanging it, do one thing first:


    SMC reset

    1. Shut down the computer.
    2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    4. Release all the keys and the power button at the same time.
    5. Press the power button to turn on the computer. 
      : The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.


    Still same?



    On a new macbook Air, there is no need to fuss with it, return it for another Air in exchange. 


    Messing with it / diagnostics at this point are fruitless when you can exchange it, especially on a power issue.
