Apple PowerBook (Duo 270C) - Manual (Page 256)

s Warning: Use only the power adapter that came with your
PowerBook Duo. Adapters for other electronic devices
(including other portable computers) may look similar, but
they may damage your computer.
s
If you are connecting only an external floppy disk drive, a
keyboard, and/or a mouse, you don’t need to plug in the power
adapter.
3. If you are connecting an external monitor, plug the
monitor’s power cord into an electrical outlet or power
strip. Then connect the monitor’s video cable to the
video port (marked with the icon ™) on the Duo
MiniDock.
You may find that your monitor’s power cord is designed to
plug into the power receptacle on the back of a computer,
rather than into an electrical outlet. Your Apple-authorized
dealer can supply a power cord with the correct plug.
