Using Your iBook G4 When you use your iBook or charge its battery, it is normal for the bottom of the case to get warm. For prolonged use, place your iBook on a flat, stable surface. The bottom of the iBook 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: Do not place your iBook on a pillow or other soft material when it is on, because the material can 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. Understanding General Safety Instructions For your own safety and that of your equipment, always take the following precautions. Disconnect the power plug (by pulling the plug, not the cord), remove the battery, and disconnect the phone cord if any of the following conditions exists: Â You want to remove any parts. Â The power cord or plug becomes frayed or otherwise damaged. Â You spill something in the case. Â Your computer is exposed to rain or any other excess moisture. Â Your computer has been dropped or the case has been otherwise damaged. Â You suspect that your computer needs service or repair. Â You want to clean the case (use only the recommended procedure described earlier). Important: The only way to disconnect power completely is to unplug the power cord and phone cord, and remove the battery. Make sure at least one end of the power cord is within easy reach so that you can unplug the computer when you need to. Warning: Your AC cord came equipped with a three-wire grounding plug (a plug that has a third grounding pin). This plug will fit only a grounded AC outlet. If you are unable to insert the plug in to an outlet because the outlet is not grounded, use the AC plug that came with your adapter, or contact a licensed electrician to replace the outlet with a properly grounded outlet. Do not defeat the purpose of the grounding plug. Appendix B Care, Use, and Safety Information 71

Using Your iBook G4
When you use your iBook or charge its battery, it is normal for the bottom of the case
to get warm. For prolonged use, place your iBook on a flat, stable surface. The bottom
of the iBook 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

computer vents warm air from the back of the case.
