Next Steps
Firewall Software
When you use the notebook for e-mail, network, or Internet
access, it is possible for unauthorized persons to obtain
information about you, your notebook, and your data. Firewalls
monitor all incoming and outgoing traffic on your computer by
including features such as logging and reporting, automatic
alarms, and user interfaces for configuring the firewall. To protect
your privacy, it is recommended that you use
firewall software.
Your notebook comes with preinstalled firewall software. Refer to
the online Help in the firewall software application for additional
information.
✎
Under some circumstances a firewall can block access to
Internet games, interfere with printer or file sharing on a
network, or block authorized e-mail attachments. To
temporarily solve the problem, disable the firewall, perform
the task that is interfering with the firewall, and then reenable
the firewall. To permanently resolve the problem, reconfigure
the firewall.
Protect the Notebook from Power Surges
To protect the notebook from the power surges that may be
caused by an uncertain power supply or an electrical storm:
■ Plug the notebook power cord into an optional, high-quality
surge protector. Surge protectors are available from most
computer or electronics retailers.
■ Provide surge protection on the cable that connects the
modem to a telephone line.
■ During an electrical storm, either run the notebook on
battery power or shut down the notebook and disconnect
the power cord.
