Apple PowerBook (Duo 270C) - Manual (Page 259)

Before you dock
Before you connect the PowerBook Duo to the Duo MiniDock,
the computer must be shut down or in sleep.
Shut down for access to all devices
Docking with the computer shut down gives you access to SCSI
devices such as a hard disk drive or CD-ROM drive. The computer
can only recognize these devices when it is turned on (after
having been off ). When you turn the computer on, it recognizes
all attached devices (including an external monitor, floppy disk
drive, and keyboard).
Sleep for access to everything except SCSI devices
Docking with the computer in sleep gives you faster access to
most devices, including an external monitor, floppy disk drive,
keyboard, and mouse. The computer can recognize these devices
immediately when you wake it from sleep, provided they were
attached to the minidock before you connected the computer.
Docking when the computer is in sleep does not give you access
to SCSI devices until you restart the computer.
Don’t dock with the computer turned on
If you try to connect to the Duo MiniDock with the PowerBook
Duo turned on, the computer will turn itself off. This process
erases any information you did not save.
