FireWire Devices and Battery Power

FireWire devices, such as certain external hard disk drives, can get power from the iBook G4 FireWire connection instead of a separate power adapter. However, these types of FireWire devices can cause your iBook G4 battery to become depleted faster. If a device will be connected for an extended period, it is a good idea to connect the iBook G4 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. Apple recommends that 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 port may cause problems. If a problem occurs, shut down the computer, remove the FireWire devices, and restart your computer.

Connecting Your iBook G4 to Another Computer Using FireWire

You can connect two FireWire-equipped computers with a FireWire cable to transfer files. Or, if you have a problem that prevents your computer from starting up, you may be able to use FireWire to connect to another computer and access your files. When you start up your iBook G4 in FireWire Target Disk Mode, the other computer can access your iBook G4 as if it were a hard disk.

Note: When using FireWire Target Disk Mode, it’s a good idea to connect your power adapter to the iBook G4.

To connect your iBook G4 to another computer in FireWire Target Disk Mode:

1Make sure that your iBook G4 is shut down.

2Use a FireWire cable to connect your iBook G4 to another FireWire-equipped computer.

3Start up your iBook G4 and immediately hold down the T key. Your iBook G4 display shows the FireWire logo. The other computer’s display shows the iBook G4 internal hard disk icon. You can now drag and drop files between the systems.

4When you are finished transferring files, drag the iBook G4 hard disk icon to the Trash.

5Press the Power button on the iBook G4 to shut it down, and then disconnect the FireWire cable.
