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.
