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, do one of the following:
• For Windows 7, Windows 8, or Windows 8.1: Use the Fingerprint Manager Pro or ThinkVantage
Fingerprint Software program provided by Lenovo. To open the program, see "Accessing a program on
your computer" on page 4. For more information about using the program, refer to the help system
of the program.
• For Windows 10: Use the fingerprint tool provided by Windows. 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 http://www.lenovo.com/support/keyboards.
Using and understanding 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.
The Windows operating system preinstalled on your computer provides the Windows Firewall. For details on
using the Windows Firewall, refer to "Windows help system" on page 123.
Protecting data against viruses
Your computer is preinstalled with an antivirus program to help you guard against, detect, and eliminate
viruses.
Lenovo provides a full version of antivirus software on your computer with a free 30-day subscription. After
30 days, you must renew the license to continue receiving the antivirus software updates.
Note: Virus definition files must be kept up-to-date to guard against new viruses.
For more information about how to use your antivirus software, refer to the help system of your antivirus
software.
