Apple PowerBook (500 Series) - Manual (Page 41)

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.
Quitting SCSI disk mode
1 Shut down the computer your PowerBook is connected to.
2 Tap the Power On (
P
) key once to turn the PowerBook off.
3 Turn off any other SCSI devices in the chain.
4 Disconnect the PowerBook from the adapter cable.
If you regularly plan to connect your PowerBook to the same computer, you
can leave the adapter cable attached to the SCSI chain or the other computer.
IMPORTANT Do not leave the adapter cable attached to the PowerBook. If you
do, the computer will behave as though it is still in SCSI disk mode when you
try to restart.
5 If necessary, disconnect the adapter cable from the other computer or its SCSI chain.
Your equipment is now ready for normal use. Make sure that the SCSI chain
is properly terminated.
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.
