Sudden Motion Sensor
Your PowerBook has Sudden Motion Sensor technology, built-in protection for the hard
disk that is designed to help prevent disk failures if the computer is dropped or
undergoes severe vibration.
In general, Sudden Motion Sensor protection does not change hard disk performance
during regular PowerBook operation. Occasionally the Sudden Motion Sensor
technology may be activated by unusually strong vibrations at a time when your
PowerBook is writing or reading data intensively, such as when playing or recording
video or audio. Should you experience dropped frames or sound elements in such a
situation, make sure that your PowerBook is in a stable environment without vibration
or abrupt movement.
