v Show hard drive active protection icon on the system tray checkbox: If the checkbox is selected, the icon showing the status of the shock sensor is displayed in the system tray. The active protection system is enabled by default whenever the computer is operating. It is automatically disabled while the computer is: - Loading the operating system - Enter Standby or hibernation mode - Resuming normal operation after being in Standby or hibernation mode - Being shut down - Turned off 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. 6 IBM Active Protection System Whitepaper

System
Enable/Disable
feature
(user
option
via

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

vibration:
This
feature
cannot
be
manually
controlled
by
the
user.
The
Shock
Manager
ignores
impulse-type
acceleration
change
so
as
to
minimize

function
inside
the
Shock
Manager
performs
this
function.
Heuristic

feature:
This
feature
cannot
be

user.
The
sensitivity
for
shock
prediction
is
dynamically

depending
on
body
posture
change
with
received
shocks,
vibrations
and
