Important features of the IBM Active Protection System

Enable/Disable feature (user option via utility): User can manually enable and
disable the active protection system using the software user interface.
Automatic ignore feature: Sometimes the user is in an environment that has
associated vibration (such as in a car or airplane where the entire vehicle vibrates).
In these environments, the vibration may be transmitted to the ThinkPad
computer. The Automatic Ignore feature is helpful in this situation. This feature is
enabled by default, but the user can manually change choice at any time via the
software utility.
Cancel feature for impulse-type vibration: This feature cannot be manually
controlled by the user. The Shock Manager ignores impulse-type acceleration
change so as to minimize prediction failures. An adaptive low-pass filter function
inside the Shock Manager performs this function.
Heuristic sensitivity tuning feature: This feature cannot be manually controlled by
the user. The sensitivity for shock prediction is dynamically changed depending on
body posture change with received shocks, vibrations and user input activities.
Administrative lock: This feature restricts users without Administrative system
rights from changing the Active Protection System properties.

Summary

The IBM Hard Drive Active Protection System can greatly improve overall system
reliability by providing enhanced hard drive protection from shock. Using the
latest technology to constantly monitor the movement of your ThinkPad computer,
users can feel confident that their data will be better protected in the event of a
drop or similar potentially damaging event.
