Instruction Manual

If you have system problems

If your docked PowerBook crashes (the screen goes blank or fills with

gibberish) or freezes (the pointer doesn’t move and input devices don’t work),

press the power button on the back of the dock once. Pressing once turns the

PowerBook off. Use the Power On key on your external keyboard to turn the

PowerBook on again.

Pressing the power button erases any information you did not save, but it

allows you to restart the system and continue working.

See the troubleshooting information in the documentation that came with

your PowerBook for more information about handling system problems.

Using security features

The Duo Dock has a key-operated mechanical lock to prevent theft of a

docked PowerBook Duo. You can also lock PowerBooks out of the dock—for

example, to protect information on the dock’s hard disk or to limit access to

a network.

You can lock the dock when the PowerBook is inside or outside the dock.

You can lock the PowerBook inside the dock when the PowerBook is on

or off.

To lock or unlock the dock, turn the key as shown in the illustration.
