Does your MBA make a weird noise when sleeping?

    Occasionally when my MBA (2012) falls asleep (lid open) I will hear this strange electrical humming coming from the charger area. It goes away when I wake it up

    When I close the lid however this sound returns and doesn't stop until I open the lid

    Is this normal? :confused: It's not very loud however it's noticeable and quite annoying.

    It's just snoring. :D Seriously, it's perfectly fine.

    I would (if this is really loud and not your OCD):

    Try another charger.

    Clean the Magsafe's port contacts.
