    Most likely. I would go to the store and have them take a look at it.

    not necessarily - check the display settings in your system preferences first. there's a pane under "options" (in tiger, can't speak for previous versions of OS X) where you can completely disable the buttons on the cinema display. see the attached screen shot...

    thank u. the bigger issue is now when i start up my computer (it's hooked up to my g4 powerbook ti) it flickers on and off a few times and sometimes the screen starts and sometimes it just stays black (??)

    anyone else have this problem?

    It sounds like it is searching/switching the resolution and it only supports three resolutions, else it goes on black. When it stays black, do you have mirroring on? If so, turn this of, or you have the resolution of your powerbook on a resolution that the ACD doesn't support.

    Man you're my freaking hero. I was wondering how i might be able to get the power button to just turn the display on/off :)

    Now I can leave some downloads going and turn the display off while i'm away. (it does automatically turn off but hey, figure i can help it along a bit instead of waiting 10 minutes)

    I have a 1G Apple Cinema display and the power button no longer works, regardless of the System Preferences setting. The "brightness" button on the front panel works, and the power button glows when I press it, but it seems to have no effect. I used to be able to power down/sleep my system with it.
