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

Firewalls work on a set of rules to determine which inbound and outbound connections are authorized. If

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. Click the Start button to open the Start menu.
2. Click Windows System ➙ Control Panel.
3. View Control Panel by Large icons or Small icons, and then click Windows Defender Firewall.
4. Follow the instructions on the screen.
