Security Slot and Keyboard Lock
You can purchase a security cable and lock to protect your PowerBook. With a lock, you can
secure your computer to a desk or table.
Your PowerBook also comes with a keyboard locking mechanism. When the keyboard is
locked, users will be unable to easily access the internal components of the computer,
including the memory, hard disk, and optional AirPort Card.
The keyboard locking mechanism is in the small plastic tab to the left of the Num Lock key,
which also contains the Num Lock indicator light. Your PowerBook comes with the keyboard
unlocked.
To lock the keyboard, use a small flathead screwdriver to the turn the screw clockwise 1/2
turn. A small tab prevents the keyboard from being removed.
Note: The screw that turns the plastic tab has a small notch on one side that you can use to
determine if the keyboard is locked. If the notch in the screw is on the top, the keyboard is
unlocked. If the notch in the screw is on the bottom, the keyboard is locked.
