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

Shut down the computer your PowerBook is connected to.

Press the Power (π) key once on the PowerBook to get the Shut Down dialog box.

Turn off any other SCSI devices in the chain.

Disconnect 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.
