Securing your wireless network
When you set up a WLAN or access an existing WLAN, always enable security features to protect
your network from unauthorized access. WLANs in public areas (hotspots) like coffee shops and
airports may not provide any security.
Backing up your software applications and information
Regularly back up your software applications and information to protect them from being permanently
lost or damaged through a virus attack or a software or hardware failure. For more information, see
Backing up, restoring, and recovering on page 49.
Using an optional security cable lock
A security cable lock, purchased separately, is designed to act as a deterrent, but it may not prevent
the computer from being mishandled or stolen. Security cable locks are only one of several methods
that should be employed as part of a complete security solution to help maximize theft protection.
The security cable slot on your computer may look slightly different from the illustration in this section.
For the location of the security cable slot on your computer, see Getting to know your computer
on page 4.

2. Insert the key (1) into the security cable lock (2).

security cable lock with the key.
4. Remove the key and keep it in a safe place.
