Getting to Know Your New PowerBook Because your PowerBook 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 PowerBook, 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 PowerBook while discs are spinning. When using your PowerBook or when charging the battery, it is normal for the bottom of the case to get warm. For prolonged use, place your PowerBook 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 drives. For example, your hard disk and optical drives may whir and click as they access information or load and eject discs. After the PowerBook runs for some time, a small fan may turn on to cool it, producing a faint sound. Small noises are part of the PowerBook's normal functioning. For more safety instructions about handling and using your PowerBook in different locations, be sure to see Appendix B, "Care, Use, and Safety Information," on page 65. 19 Adjusting Your Display Once you begin working with your new PowerBook, you may need to adjust your display so that the screen is easier to see.
