Using fingerprint authentication
If your keyboard has a fingerprint reader, you can use fingerprint authentication to replace passwords for
simple and secure user access. To use fingerprint authentication, first enroll your fingerprints and associate
them with your passwords (such as the power-on password, hard disk password, and Windows password).
Use the fingerprint reader and the fingerprint program to complete this procedure.
To use fingerprint authentication, use the fingerprint tool provided by the Windows 10 operating system.
Click the Start button to open the Start menu, and then click
Settings ➙ Accounts ➙ Sign-in options .
Follow the instructions on the screen.
To use the fingerprint reader, refer to the documentation shipped with the fingerprint keyboard or located on
the Lenovo Support Web site at

Using the cover presence switch
The cover presence switch prevents your computer from logging in to the operating system when the
computer cover is not properly installed or closed.
To use the cover presence switch, enable the cover-presence-switch connector on the system board first. To
achieve this, do the following:
1. Start the Setup Utility program. See “Starting the Setup Utility program” on page 35.
2. Select Security ➙ Chassis Intrusion Detection and press Enter.
3. Select Enabled and press Enter.
4. To save settings and exit the Setup Utility program, press F10 or Fn+F10 (depending on the keyboard
settings), select Yes in the window displayed, and press Enter. The cover-presence-switch connector on
the system board is enabled.
The cover presence switch starts functioning. If the switch detects that the computer cover is not correctly
installed or closed, an error message is displayed when you turn on the computer. To fix the error and log in
to the operating system, do the following:
1. Properly remove or install your computer cover. See Chapter 7 “Hardware removal and installation” on
page 59.
2. Start and then exit the Setup Utility program. See “Starting the Setup Utility program” on page 35 and
“Exiting the Setup Utility program” on page 40.
Using firewalls
A firewall can be hardware, software, or a combination of both depending on the level of security required.
Firewalls work on a set of rules to determine which inbound and outbound connections are authorized. If
your computer is preinstalled with a firewall program, it helps protect against computer Internet security
threats, unauthorized access, intrusions, and Internet attacks. It also protects your privacy. For more
information about how to use the firewall program, refer to the help system of your firewall program.
