Working with a Powerbook Duo System
This section summarizes
n
how your PowerBook Duo behaves when it is docked, or
when it is moved from one Duo Dock to another
n
how to take advantage of the Duo Dock’s features
Your preferences
The PowerBook Duo uses your preferences—including desktop
pattern, window views, and so forth—when you dock it. This
means that your computer will be customized the way you like it
no matter where you work.
The PowerBook Duo can also remember certain selections that
apply only when you are docked (such as an Ethernet network
setting). Each time you dock, these settings take effect again
without any action on your part.
Battery recharging
A docked PowerBook Duo draws power from the Duo Dock, not
from its own battery. The battery recharges while the computer is
in the dock.
You can remove the battery before docking if you want to
recharge it in a recharger. You can also remove the battery from
the computer while it is docked if you want to recharge a second
battery inside the computer.
Power conservation
A docked PowerBook Duo does not sleep. You cannot put the
PowerBook to sleep as long as it remains docked.
The microprocessor in a docked PowerBook Duo does not
cycle on and off, because there is no need to limit its power
consumption.
