Apple PowerBook (200 Series) - Manual (Page 46)

Simplifying the connection process
If you regularly plan to use your PowerBook as a SCSI disk with the same
computer, you can leave the SCSI disk adapter cable attached to the other
computer or its SCSI chain. When you want to use your PowerBook as a
SCSI disk, simply shut down all devices and connect the adapter cable to the
SCSI port on your PowerBook Duo MiniDock.
Drawing battery power in SCSI disk mode
Your PowerBook continues to draw battery power when you use it as a SCSI
disk. Low battery power is indicated by a blinking low-power warning on the
PowerBook’s screen.
If you see this warning while using your computer as a SCSI disk, either plug
in the power adapter or quit SCSI disk mode, as described in the next section,
so you can remove the battery for recharging.
WARNING Always disconnect your PowerBook from the adapter cable
when you are not using it as a SCSI disk. Your PowerBook will not
work correctly if the adapter cable remains attached.
Connect and disconnect your computer here.
These cables can stay attached to your
other computer or its SCSI chain.
