2 The Basics
This chapter introduces important basics about your
iBook G4 that you’ll want to know.
Getting to Know Your iBook G4
Because your iBook G4 is so thin and light, you can take it with you to the office, library,
class, or wherever you work or play.
Whenever you stop using your iBook G4, wait a few moments to let the hard disk and
any optical disc in your drive stop spinning before you transport the computer. Avoid
jostling or bumping your iBook G4 while discs are spinning.
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 case is raised slightly to allow airflow that keeps the unit within
normal operating temperatures.
As you get to know your new computer, you may hear small noises during startup and
when using your hard disk and optical drive. For example, your hard disk and optical
drive may whir and click as they access information or load and eject discs. After the
computer runs for some time, a small fan may turn on to cool it, producing a faint
sound. Small noises are part of the computer’s normal functioning.
For more safety instructions about handling and using your iBook G4 in different
locations, be sure to see Appendix B, “Care, Use, and Safety Information,” on page 69.
