To enable the cover-presence-switch connector on the system board, do the following:

2. Select Security ➙ Chassis Intrusion Detection and press Enter.
3. Select Enabled and press Enter.
4. Exit the Setup Utility program. See "Exiting the Setup Utility program" on page 63.
When the cover-presence-switch connector on the system board is enabled, if the cover presence switch
detects that the computer cover is not correctly installed or closed, an error message will be displayed when
you turn on the computer. To bypass the error message and log in to the operating system, do the following:
1. Properly install or close the computer cover.
2. Start and then exit the Setup Utility program. See "Starting the Setup Utility program" on page 59 and
"Exiting the Setup Utility program" on page 63.

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 the
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.
To use Windows Firewall, do the following
1. Depending on your Windows version, do one of the following:
• For Windows 7: Click Control Panel on the Start menu.
• For Windows 10: Click the Start button to open the Start menu, and then click Windows System ➙
Control Panel.
2. View Control Panel using large icons or small icons, and then click Windows Firewall.
3. Follow the instructions on the screen.

Protecting data against viruses

The 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 the 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.
