							Sharing optical drives
Although your computer may not have an integrated optical drive, you can access software and data,
and install applications, by sharing an optical drive connected to another computer in your network.
Sharing drives is a feature of the Windows operating system that allows a drive on one computer to
be accessible to other computers on the same network.
NOTE:You must have a network set up in order to share an optical drive; refer to Networking
(select models only) on page 2 for additional information on setting up a network.
NOTE:Some discs, such as DVD movies and game discs, may be copy-protected and therefore
unusable through DVD or CD drive sharing.
To share an optical drive:
1.From the computer with the optical drive you are sharing, select Start > Computer.
2.Right-click the optical drive you want to share, and click Properties.
3.Select the Sharing tab > Advanced Sharing.
4.Select the Share this folder check box.
5.Type a name for the optical drive in the Share name text box.
6.Click Apply, and then click OK.
7.To view the shared optical drive:
Select Start > Control Panel > Network and Internet > Network and Sharing Center.
Using RAID (select models only)
Redundant Arrays of Independent Disks (RAID) technology allows a computer to use two or more
hard disks at the same time. RAID treats multiple drives as one contiguous drive, either through
hardware or software settings. If multiple disks are set up to work together in this fashion, they are
referred to as a RAID array.
For additional information about RAID, refer to the HP Web site at 
http://www.hp.com/support.

Using antivirus software
When you use the computer to access e-mail, a network, or the Internet, you potentially expose it to
computer viruses. Computer viruses can disable the operating system, programs, or utilities, or cause
them to function abnormally.
Antivirus software can detect most viruses, destroy them, and, in most cases, repair any damage they
have caused. To provide ongoing protection against newly discovered viruses, antivirus software
must be kept up to date.
An antivirus program may be preinstalled on your computer and may include a trial offer. It is strongly
recommended that you upgrade the trial offer or purchase the antivirus program of your choice in
order to fully protect your computer.
For more information about computer viruses, type viruses in the Search box in Help and Support.
Using firewall software
Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be a
software program you install on your computer and/or network, or it can be a solution made up of
both hardware and software.
Using antivirus software 47 
						

							There are two types of firewalls to consider:
●Host-based firewalls—Software that protects only the computer it is installed on.
●Network-based firewalls—Installed between your DSL or cable modem and your home network
to protect all the computers on the network.
When a firewall is installed on a system, all data sent to and from the system is monitored and
compared with a set of user-defined security criteria. Any data that does not meet those criteria is
blocked.
Your computer or networking equipment may already have a firewall installed. If not, firewall software
solutions are available.
NOTE: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 resolve the
problem, disable the firewall, perform the task that you want to perform, and then reenable the
firewall. To permanently resolve the problem, reconfigure the firewall.
Installing critical security updates
CAUTION:Microsoft sends out alerts regarding critical updates. To protect the computer from
security breaches and computer viruses, install all critical updates from Microsoft as soon as you
receive an alert.
Updates to the operating system and other software may have become available after the computer
left the factory. To be sure that all available updates are installed on the computer, observe these
guidelines:
●Run Windows Update as soon as possible after you set up your computer. Use the update link
at Start > All Programs > Windows Update.
●Run Windows Update monthly thereafter.
●Obtain updates to Windows and other Microsoft® programs, as they are released, from the
Microsoft Web site and through the updates link in Help and Support.
Installing an optional security cable
NOTE:A security cable is designed to act as a deterrent, but it may not prevent the computer from
being mishandled or stolen.
NOTE:The security cable slot on your computer may look slightly different from the illustration in
this section. Refer to the Getting Started guide for the location of the security cable slot on your
computer.
1.Loop the security cable around a secured object.
2.Insert the key (1) into the cable lock (2).
48 Chapter 7   Security 
						

							3.Insert the cable lock into the security cable slot on the computer (3), and then lock the cable lock
with the key.
4.Remove the key and keep it in a safe place.
Using the fingerprint reader (select models only)
Integrated fingerprint readers are available on select computer models. In order to use the fingerprint
reader, you must set up a user account with a password on the computer. This account allows you to
log on to your computer with a swipe of a designated finger. You may also use the fingerprint reader
to fill in password fields on Web sites and other programs that require a logon. Refer to the fingerprint
software Help for instructions.
After you create your fingerprint identity, you can set up a Single Sign On service that allows you to
use your fingerprint scanner to create credentials for any application that requires a user name and
password.
Locating the fingerprint reader
The fingerprint reader is a small metallic sensor that is located in one of the following areas of your
computer:
●Near the bottom of the TouchPad
●On the right side of the keyboard
●On the upper-right side of the display
●On the left side of the display
Depending on your computer model, the fingerprint reader may be oriented horizontally or vertically.
Both orientations require that you swipe your finger perpendicular to the metallic sensor. Refer to the
Getting Started guide for the location of the fingerprint reader on your computer.

							8 Maintenance
Cleaning your computer
Cleaning the display
CAUTION:To prevent permanent damage to the computer, never spray water, cleaning fluids, or
chemicals on the display.
To remove smudges and lint, frequently clean the display with a soft damp, lint-free cloth. If the
screen requires additional cleaning, use premoistened antistatic wipes or an antistatic screen cleaner.
Cleaning the sides and cover
To clean and disinfect the sides and cover, use a soft microfiber cloth or a static-free cloth without oil
(such as a chamois) moistened with an alcohol-free glass cleaner or use an acceptable germicidal
disposable wipe.
NOTE:When cleaning the cover of the computer, use a circular motion to aid in removing dirt and
debris.
Cleaning the TouchPad and keyboard
Dirt and grease on the TouchPad can cause the pointer to jump around on the screen. To avoid this,
clean the TouchPad with a damp cloth, and wash your hands frequently when using the computer.
WARNING!To reduce the risk of electric shock or damage to internal components, do not use a
vacuum cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris
on the keyboard surface.
Clean the keyboard regularly to prevent keys from sticking, and to remove dust, lint, and particles that
can become trapped beneath the keys. A can of compressed air with a straw extension can be used
to blow air around and under the keys to loosen and remove debris.
Updating programs and drivers
HP recommends that you update your programs and drivers on a regular basis with the latest
versions. Go to 
http://www.hp.com/support to download the latest versions. You can also register to
receive automatic update notifications when they become available.
