							Updating programs and drivers
HP recommends that you update your programs and drivers on a regular basis to the latest versions
because if you dont, you wont know what youre missing! Updates can fix issues and bring new
features and options to your computer. Technology is always changing and updating programs and
drivers allows your computer to run the latest technology available. For example, an older graphics
card might not work well with the most recent gaming software unless it has a driver that can translate
the newest commands. Without the latest driver, your graphics card might still work, but you would
not be getting the most out of your equipment!
Go to the HP website to download the latest versions of HP programs and drivers. For U.S. support,
go to 
http://www.hp.com/go/contactHP. For worldwide support, go to http://welcome.hp.com/country/
us/en/wwcontact_us.html. In addition, register to receive automatic update notifications when they
become available.
Cleaning your computer
Cleaning your computer and peripherals helps keep them in good working condition. If you dont
clean your computer, dust and dirt particles can build up.
CAUTION:Avoid using the following cleaning products to clean your computer:
Strong solvents, such as alcohol, acetone, ammonium chloride, methylene chloride, and
hydrocarbons, which can permanently damage the surface of the computer.
Cleaning the display, sides, and cover
Gently wipe the display using a soft, lint-free cloth moistened with an alcohol-free glass cleaner. Allow
the display to dry before closing the computer cover.
Use a pre-moistened germicidal wipe to clean the sides and cover. Fibrous materials, such as paper
towels, can scratch the computer.
NOTE:When cleaning the cover of the computer, use a circular motion to aid in removing dirt and
debris.
Cleaning the TouchPad and keyboard
CAUTION:Never allow liquids to drip between the keys on the keyboard, even when you are
cleaning the computer. This can permanently damage internal components.
●To clean and disinfect the TouchPad and keyboard, use a soft microfiber cloth or a static-free
cloth without oil (such as a chamois cloth) moistened with an alcohol-free glass cleaner or use
an acceptable germicidal disposable wipe.
●To prevent keys from sticking and to remove dust, lint, and particles from the keyboard, use a
can of compressed air with a straw extension.
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.

							Traveling with your computer
Taking your computer with you on a trip might seem to overload some people and to others it is a
“must have” to stay connected. Whichever category you fall in, if you have to travel with your
computer here are some things to keep in mind before and during your travel to keep your equipment
safe. Following are some computer travel and shipping tips to help make your trip a little less
stressful.
●Prepare the computer for traveling or shipping:
◦Back up your information to an external drive.
◦Remove all discs and all external media cards, such as digital storage cards, from the
computer.
◦Turn off, and then disconnect all external devices.
◦Remove any media from the drive before removing the drive from a drive bay.
CAUTION:Perform this action before shipping, storing, or traveling with a drive. This will
help reduce the risk of damage to the computer, damage to a drive, or loss of information.
◦Shut down the computer.
●Take along a backup of your information. Keep the backup separate from the computer.
●When traveling by air, carry the computer as hand luggage; do not check it in with the rest of
your luggage.
CAUTION:Avoid exposing a drive to magnetic fields. Security devices with magnetic fields
include airport walk-through devices and security wands. Airport conveyer belts and similar
security devices that check carry-on baggage use X-rays instead of magnetism and do not
damage drives.
●If you plan to use the computer during a flight, listen for the in-flight announcement that tells you
when you are allowed to use your computer. In-flight computer use is at the discretion of the
airline.
●If the computer will be unused and disconnected from external power for more than 2 weeks,
remove the battery and store it separately.
●If you are shipping the computer or a drive, use suitable protective packaging and label the
package “FRAGILE.”
●If the computer has a wireless device installed, the use of these devices may be restricted in
some environments. Such restrictions may apply onboard aircraft, in hospitals, near explosives,
and in hazardous locations. If you are uncertain of the policy that applies to the use of a
particular device, ask for authorization to use your computer before you turn it on.
●If you are traveling internationally, follow these suggestions:
◦Check the computer-related customs regulations for each country or region on your
itinerary.
◦Check the power cord and adapter requirements for each location in which you plan to use
the computer. Voltage, frequency, and plug configurations vary.
WARNING!To reduce the risk of electric shock, fire, or damage to the equipment, do not
attempt to power the computer with a voltage converter kit sold for appliances.

							9 Securing your computer and
information
Computer security is essential for protecting the confidentiality, integrity, and availability of your
information. Standard security solutions provided by the Windows operating system, HP applications,
the non-Windows Setup Utility (BIOS), and other third-party software can help protect your computer
from a variety of risks, such as viruses, worms, and other types of malicious code.
IMPORTANT:Some security features listed in this chapter may not be available on your computer.
Computer risk Security feature
Unauthorized use of the computer Power-on password
Computer viruses Antivirus software
Unauthorized access to data Firewall software
Unauthorized access to Setup Utility (BIOS) settings and
other system identification informationAdministrator password

							Locating your security software
HP Security Assistant provides a starting location for you to quickly access a collection of security
software applications that are organized by task. Instead of searching for each application through the
Start menu and Control Panel, HP Security Assistant allows you to access the applications for the
following security tasks:
●Set up Internet and antivirus security.
●Back up and recover files.
●Manage passwords, user accounts, and parental controls.
●Maintain your computer and install the latest HP and Windows updates.
To open HP Security Assistant, select Start > All Programs > Security and Protection > HP
Security Assistant.
Using passwords
A password is a group of characters that you choose to secure your computer information and to
protect online transactions. Several types of passwords can be set. For example, when you set up
your computer for the first time, you were asked to create a user password to secure your computer.
Additional passwords can be set in Windows or in the HP Setup Utility (BIOS) that is preinstalled on
your computer.
You may find it helpful to use the same password for a Setup Utility (BIOS) feature and for a Windows
security feature.
Use the following tips for creating and saving passwords:
●To reduce the risk of being locked out of the computer, record each password and store it in a
secure place away from the computer. Do not store passwords in a file on the computer.
●When creating passwords, follow requirements set by the program.
●Change your passwords at least every three months.
●An ideal password is long and has letters, punctuation, symbols, and numbers.
●Before you send your computer for service, back up your files, delete confidential files, and then
remove all password settings.
For additional information about Windows passwords, such as screen-saver passwords, select Start
> Help and Support.

							Using Internet security software
When you use your computer to access email, a network, or the Internet, you potentially expose your
computer to computer viruses, spyware, and other online threats. To help protect your computer,
Internet security software that includes antivirus and firewall features may be preinstalled on your
computer as a trial offer. To provide ongoing protection against newly discovered viruses and other
security risks, security software must be kept up to date. It is strongly recommended that you upgrade
the security software trial offer or purchase the software of your choice in order to fully protect your
computer.
Using antivirus software
Computer viruses can disable programs, utilities, or the operating system, or cause them to function
abnormally. Antivirus software can detect most viruses, destroy them, and in most cases, repair any
damage they have caused.
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
software you install on your computer and/or network, or it can be a combination of both hardware
and software.
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.

							Installing software updates
HP, Microsoft Windows, and third-party software installed on your computer should be regularly
updated to correct security problems and improve software performance.
Installing Windows security updates
Updates to the operating system and other software may have become available after the computer
left the factory. 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.
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. Select 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 website and through the updates link in Help and Support.
Installing HP and third-party software updates
HP recommends that you regularly update the software and drivers that were originally installed on
your computer. To download the latest versions, go to the HP website. For U.S. support, go to
http://www.hp.com/go/contactHP. For worldwide support, go to http://welcome.hp.com/country/us/en/
wwcontact_us.html. At this location, you can also register to receive automatic update notifications
when they become available.
If you have installed third-party software after you purchased your computer, regularly update the
software. Software companies provide software updates to their products to correct security problems
and improve functionality of the software.
