    Using the "wake reason" command in my terminal, i found out that no matter if "acwake" is 0 or 1, my mba wake up when I attach or detach the ac power cord. On top of that, it does not completely wakes, as I still have to perform another action for the screen to successfully brighten.

    From reading on a bunch of places, I thought that acwake 0 meant that attaching/detaching the power would not induce the mac to wake up.

    I tested it doing the following:

    - ACWAKE 0 or 1.

    - with the lid open, pressed the power button and hit the sleep option.

    - attach the power. wait a few secs. detach the power.

    - in both cases nothing happens. It really shouldn't with acwake 0 but with acwake 1 it should. I then have to press buttons in order to do it.

    - Now I go to the terminal and find out that in both cases again (acwake 0 and 1), these lines showed up:

    kernel[0] <Debug>: Wake reason: EC.ACAttach (Maintenance)
    kernel[0] <Debug>: Wake reason: EC.ACDetach (Maintenance)

    This means that in BOTH cases, the mac has woken up, no matter if acwake was 0 or 1, while it should only happen with acwake 1. But even with acwake 1, the screen was black, and I had to press a button in order to wake it up, as described.

    What the hell is going on?

    Any tips?

    If its confusing, please tell me so I can explain again.

    Is there some place else on the net I should try asking this question?
