    I've got a MacBook Air 13 (2012)

    It's starts with a generic Ac power adapter but it does not charging the battery and the MagSafe LED never lights...

    When i try a official power adapter; it's not turn on, it's not charging and the led dont' light....

    with the generic power adapter, i've got this informations on the Mac :

    Informations de l’adaptateur secteur :

    Connecté : Oui

    Identifiant : 0x0000

    Révision : 0x0000

    Famille : 0x0000

    Nº de série : 0x00000000

    En cours de chargement : Non

    When i try "without SMC", both power adapter work... with the fan very fast , but not charging and without led on the magsafe.

    but none recognized by the mac, no info.

    to sum up the situation :

    with SMC

    generic power adapter : turn on the mac, don't charging

    official power adapter : don't turn on the mac, don't charge

    "without SMC"

    generic power adapter : turn on the mac, don't charge

    official power adapter : turn on the mac, don't charge

    the magsafe LED never lights.

    it's could be a problem of the i/o board ?

    help !!! please. (sorry for my english)

    I belive there was a change in the mag-safe connections over time. My wife has a 2012 MBP and I am waiting for a reason to update by older 2010 AIR. There was a 2008 MBA in the house and depending on where we plug them into to charge some will not charge with certain mag-safe ends.

    Note: all are original Apple connections.

    I try with a old official power adapter (mavbook pro 2010) with a magasafe converter.
    Same problem. The macbbook air (2012) don't turn on and there is no light on the magsafe..

    I'm waiting for a I/O board, i just ordered...

    I hope this will solve my problem
