Getting to Know Your MacBook

This chapter introduces important basics about your MacBook. Whenever you stop using your MacBook, wait a few moments to let the hard disk and any optical disc (such as a CD or DVD) in your drive stop spinning before you transport the computer. Avoid jostling or bumping your MacBook while discs are spinning.

Note: Your MacBook uses Sudden Motion Sensor technology to help protect the hard disk if the computer is dropped or shaken. See “Understanding Sudden Motion Sensor” on page 74 for more information.

When you use your MacBook or charge its battery, it is normal for the bottom of the case to get warm. For prolonged use, place your MacBook on a flat, stable surface. The bottom of the case is raised slightly to allow airflow that keeps the unit within normal operating temperatures.

You might hear system sounds during startup and when using your hard disk and optical drive. After the MacBook runs for some time, a small fan might turn on to cool it, producing a faint sound. System sounds such as these are part of the computer’s normal functioning.
