Free Fall Sensor
Free fall sensor protects your computer hard drive from possible damage, by detecting a free
fall state caused by accidentally dropping the computer. When a free fall state is detected,
the hard drive is placed in a safe state to protect against damage to the read/write head and
possible data loss. Your hard drive returns to normal operation, when the free fall state is no
longer detected.
FastAccess Facial Recognition (Optional)
Your computer may have the FastAccess facial recognition feature. This feature helps keep your
Alienware computer secure by using the unique appearance of your face to verify your identity
and automatically supply login information that you would normally enter manually, such as
a user ID and password for a Windows account or a secure web site. For more information, click
