FireWire Devices and Battery Power

FireWire devices, such as certain external hard disks that get power from the FireWire connection instead of a separate power adapter can be used with your PowerBook. However, these types of FireWire devices can cause your PowerBook battery to become depleted faster. If a device will be connected for an extended period, it is a good idea to plug in the

power adapter.

Note: The FireWire port is designed to support power for FireWire devices (up to 7 watts maximum). You can connect multiple devices to each other and connect the “daisy-chain” of devices to the FireWire port on your computer, but only one device should get power from the computer. The rest of the devices in the daisy-chain should be powered by separate power adapters. Connecting more than one FireWire device that gets power from the computer may cause problems. If a problem occurs, shut down the computer, remove the FireWire devices, and restart your computer.

FireWire Target Disk Mode

If you want to transfer files between your PowerBook and another FireWire-equipped computer, or you have a problem that prevents your computer from starting up, you can use FireWire Target Disk Mode to connect to another computer.

Important The computer you connect your PowerBook to must have FireWire version 2.3.3 or later installed. Use Apple System Profiler, available in the Apple menu in Mac OS 9 and in the Utilities folder in the Applications folder in Mac OS X, to check the version of FireWire installed on your computer.

To connect your PowerBook in FireWire Target Disk Mode, follow these steps:

1Make sure that your PowerBook is shut down.

2Use a FireWire cable with a standard 6-pin connector on each end to connect your PowerBook to another FireWire-equipped computer.

3Start up your PowerBook and immediately hold down the T key. Your PowerBook display shows the FireWire logo, and the PowerBook internal hard disk icon appears on the desktop of the other computer.

4When you are finished transferring files, drag the PowerBook hard disk icon to the Trash.

5Press the Power button on the PowerBook to shut it down and then disconnect the FireWire cable.
