Using the Fingerprint Scanner
(Optional)
CAUTION:
For optimal performance, both the scanning surface and the
finger should be clean and dry. Clean the scanning surface
when needed. (See “Cleaning the Fingerprint Scanner” later.)
It is not recommended that you use the fingerprint scanner
in a below-
freezing temperature. The moisture on your finger can freeze
to the scanner’s metal surface when you touch it, resulting
in a failed operation. Besides, touching freezing metal with
your finger can cause frostbite.
The fingerprint scanner (if your model has the feature) provides a strong
authentication mechanism based on fingerprint recognition. You can log on to Windows
and dismiss the lock screen with an enrolled fingerprint instead of a password.
