    Hi Gang,

    Been doing the "brain transfer" for most of the weekend and I must say that I am really impressed with this thing.

    I was wondering how long it is taking for everyone's battery to charge?

    It seems that mine takes quite a while, maybe 5 or 6 hours, though the charge does last a long time, about the same I would guess.

    Any info would be appreciated.

    Also, is there a particular method to calibrate this battery. I haven't found anything on the Apple site yet?

    Best,

    Tom

    Let it drain out.

    Also if you want to adjust your battery charging times. Takes me only a couple hours to charge the battery fully.

    Do a SMU reset:

    Shut down MBA
    Unplug power adapter
    Hold down left **** key, left control key, left option key and press the power button down once while holding down those keys
    Let go, start up MBA.

    If I got 5-6 hours out of a charge, I wouldn't be unhappy at all if it took that amount of time to charge.

    Thanks for the info, however, I'm not sure what the **** key is?

    That would be the Shift key missing an F. :)

    I am pretty sure it was a typo and he meant the left shift key and the typo was censored out by the forum software.

    Just for future reference and an FYI. The process described is called "COPS" named so because the first letters of all the buttons pressed spell COPS (Control, Option, Power, ShiFt). A number of other posts mention COPS without stating explicitly what it is and I had no idea what they were talking about.
