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 preintalled 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 “Help and Support” on page 117.

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-daysubscription. After 30 days, you must renew the license to continue receiving the antivirus software updates.

Note: Virus definition files must be keptup-to-dateto guard against new viruses.

Chapter 5. Installing or replacing hardware

This chapter provides instructions on how to install or replace hardware for your computer.

Handling static-sensitivedevices

Do not open the static-protectivepackage containing the new part until the defective part has been removed from the computer and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage computer components and parts.

When you handle parts and other computer components, take these precautions to avoid static-electricitydamage:

Limit your movement. Movement can cause static electricity to build up around you.

Always handle parts and other computer components carefully. Handle PCI cards, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.

Prevent others from touching the parts and other computer components.

Before you replace a new part, touch the static-protectivepackage containing the part to a metalexpansion-slotcover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity from the package and your body.

When possible, remove the new part from the static-protectivepackaging, and install it directly in the computer without setting the part down. When this is not possible, place thestatic-protectivepackage that the part came in on a smooth, level surface and place the part on it.

Do not place the part on the computer cover or other metal surface.
