    Hello all,

    Just a quick question to all you macbook and apple cinema displays owners out there, can you turn on the macbook once it has been shutdown using the ACD power button on the side of the panel?

    I believe that only works on the older (plastic) ACDs. I could be wrong though. I have yet to plug my new MacBook into either of my ACDs.

    No. The ADC interface on the older Macs video cards and ACDs carried the power for the display, so they could turn on the Mac (if you set System Preferences to allow it).

    The new ACDs use DVI which does not carry power.

    It is not called "ACD"

    Just for those of you who didn't know, and for those who may be searching for "ADC" instead of "ACD", the connector is called an "ADC" connector. It stands for Apple Display Connector. Anyways, Just wanted to let you know.

    CWallace is right, DVI does not carry power, and thus cannot power on a machine.
