Drawing battery power in SCSI disk mode
Your Macintosh PowerBook continues to draw battery power when you use it
as a hard disk. Therefore, it is preferable to connect the power adapter
whenever you use the computer in SCSI disk mode.
IMPORTANT
If you use the PowerBook in SCSI disk mode under battery
power, the battery may be drained and the computer shut down without a
warning appearing on the screen.
In some instances a low power indicator may be displayed. This symbol is a
blinking low-power warning on the PowerBook’s screen, like the icon below.
If you see this warning while using your computer as a hard disk, either plug
in the power adapter or quit SCSI disk mode, as described in the next section,
so you can recharge the battery.
Quitting SCSI disk mode
1Shut down the computer your PowerBook is connected to.
2Press the Power (
π
) key once on the PowerBook to get the Shut Down dialog box.
3 Turn off any other SCSI devices in the chain.
4Disconnect the PowerBook from the adapter cable.
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.
5If necessary, disconnect the adapter cable from the other computer or its SCSI chain.
Your equipment is now ready for normal use. If you disconnected the adapter
cable from the other computer or SCSI chain, make sure that the SCSI chain
is properly terminated.
