Fingerprint readers can be located on the touchpad, on a side panel of the computer, or on the top cover
below the keyboard.
IMPORTANT: To verify that your computer supports fingerprint reader sign-in, select the Search icon
in the taskbar, type Sign-in options in the search box, and then select the Sign-on options app. If
Fingerprint recognition is not listed as an option, then your notebook does not include a fingerprint
reader.
