    When my G3 goes to sleep, it wakes but the screen stays dark.

    I can barely see what's on the screen.

    I have to restart.

    The screen appears for a moment, then goes dark.

    I have to push the bright button, even though it's on FULL, to get the screen to illuminate as normal.

    :confused:

    PLS HELP!

    Thanks!

    I had exactly the same problem on my PowerBook G3 after Mac OS X crashed because the battery slipped out and I had to restart.

    It was driving me nuts too... So what to do is booting in Mac OS 9 (+booting the PRAM) and then go into the Preferences folder in your User Library. Apparently the System Preferences file is broken.

    Delete "com.apple.systempreferences.plist" and restart the system in Mac OS X... voilà, everything should be fine again. But don't forget to do a backup for the file... just in case.
