TOPIC

    On most PowerBook and iBook computers, display brightness and volume keys do not work with Mac OS X 10.0.

DISCUSSION

    Symptom

    You press a function key (or dedicated button on some models), and the expected adjustment to display brightness or volume does not occur.

    Note: The behavior of affected computers varies. On the PowerBook G4, for example, you may adjust volume using the keyboard but not display brightness. Other computers, such as the PowerBook (FireWire), may not be able to use either display or volume keys.

    Products affected
    • PowerBook G3 Series
    • PowerBook G3 Series (Bronze Keyboard)
    • PowerBook (FireWire)
    • PowerBook G4
    • iBook
    • iBook (FireWire)
    • Apple Pro Keyboard (when connected to a PowerBook or iBook)

    Solution
      1. Choose System Preferences from the Apple menu.
      2. Use the Displays and Sound panes in System Preferences to make the desired adjustments.

    Apple is aware of this issue and may address it in a later version of software. This issue does not indicate any failure of your keyboard or computer hardware.
