• Fully charge and then remove your iBook G4 battery when storing your computer
(especially important when storing your computer for longer than 5 months).
Safety Instructions for Setting Up and Using
Your Computer
Plugging In the Power Adapter
Always leave space around your power adapter. Do not use this equipment in a
location where airflow around the power adapter or computer is confined. Always
disconnect the power adapter and remove the battery before opening the computer to
perform procedures such as installing memory or removing the hard disk.
Connecting a Phone Line to the Internal Modem
Always disconnect the phone cord before opening the computer to perform
procedures such as installing memory or removing the hard disk.
Using Your iBook G4
When using your iBook G4 or when charging the battery, it is normal for the bottom of
the case to get warm. For prolonged use, place your iBook G4 on a flat, stable surface.
The bottom of the iBook G4 case functions as a cooling surface that transfers heat from
inside the computer to the cooler air outside. The bottom of the case is raised slightly
to allow airflow that keeps the unit within normal operating temperatures. In addition,
the computer vents warm air from the back of the case.
Warning: Use only the power adapter that came with your iBook G4 computer.
Adapters for other electronic devices (including other iBook G4 models and other
portable computers) may look similar, but they may affect your computer’s
performance or damage it.
Warning: Do not connect a digital telephone line to the modem, because the wrong
type of line could damage the modem.
Warning: Do not place your iBook G4 on a pillow or other soft material when it is on,
as the material may block the airflow vents, in particular the rear vents, and cause the
computer to overheat. Never place anything over your keyboard before closing the
display. This can cause your computer to cycle on and off which may create excessive
heat and drain your battery. Never turn on your computer unless all of its internal and
external parts are in place. Operating the computer when it is open or missing parts
can be dangerous and can damage your computer.
