    I just got my new charger shipped over to me in Fiji. So its been a bit voer a month since I have used my macbook air.

    When i charged my laptop, the light was green.

    This is the basic i know of my macbook air -
    1. the light will be red WHILE it is charging
    2. when it is FULLY CHARGED than only will the light turn green

    Perhaps, the light is green when it is plugged in because the battery is SO FLAT?

    Please Help

    Your post is a bit confusing. It sounds like the light is green, even when your battery is not fully charged. I also have no idea what you mean by "so flat".

    Either way, the charger light is sometimes finicky. The best way to tell what is going on is to look at the Battery Usage Information bar at the top right-hand corner of the screen. If it has a little lightning bolt going through the battery, it is charging. If it has a little male connector on the battery, the charger is plugged in but not charging.

    If your computer is not at full charge and has a green light, remove the charger from your laptop and plug it back in again. If that does not work, unplug the charger from the wall, and plug it back in again. If that does not work, try a different outlet.

    I agree about the light, it can be funny sometimes. Mine's sometimes green when it's not full, or even not lighted up at all.

    I do notice it often goes green first then turn orange after a few seconds.

    I think the amber light is when it is fast charging. After it gets close to full charge, the charger tapers off the charge rate and the light turns green.

    This is what I am seeing on mine

    If its a genuine Apple charger, it should work the way you think it will, but if its a fake—not Apple—it won't, and most of those just tell you, with a green LED, that the "charger" is powered-up.

    On Apple's MagSafe connector there is a circuit board that communicates with the laptop, to regulate the charging process and control the LED; the fakes don't have that.

    If you have access to a multimeter, you can check the output of the "charger"—it isn't really a charger, its just a power supply; the charging circuitry is in the laptop. If you measure more than six volts between pins 1 and 2 (or 4 and 5) it is not an Apple charger, and the LED will never tell you anything useful. If its a fake, I recommend that you get an Apple "charger.'

    If its an Apple charger, you can disregard my post.

    Mine goes green for about 3 seconds when first connected regardless of battery charge. After those first few seconds it switches to orange to indicate it is charging. I'm assuming it does this as a test of the charging components?

    My MBA charger turns green for a few seconds as well, then turns amber for charging. I do have trouble when my MBA is connected to my 27" ACD's charger via the MagSafe II Adapter from Apple. That thing is REALLY buggy. It hardly lights at all and doesn't charge the MBA half the time. It lights a very dull green if at all. Apple REALLY messed up with the MagSafe II adapter (and I bought it at an Apple store).
