							8 Maintaining your computer
It is important to perform regular maintenance to keep your computer in optimal condition. This chapter
provides information about improving the performance of your computer by running tools such as Disk
Defragmenter and Disk Cleanup. It also provides information about updating your programs and
drivers, instructions for cleaning your computer, and tips for traveling with your computer.
Improving performance
Everyone wants a fast computer and by performing regular maintenance tasks, using tools such as Disk
Defragmenter and Disk Cleanup, you can drastically improve the performance of your computer.
Using HP 3D DriveGuard
HP 3D DriveGuard protects a hard drive by parking the drive and halting data requests under either of
the following conditions:
●You drop the computer.
●You move the computer with the display closed while the computer is running on battery power.
A short time after the end of one of these events, HP 3D DriveGuard returns the hard drive to normal
operation.
NOTE:Because solid-state drives (SSD) lack moving parts, HP 3D DriveGuard is unnecessary.
NOTE:Hard drives in the primary hard drive bay are protected by HP 3D DriveGuard. Hard drives
connected to USB ports are not covered by HP 3D DriveGuard.
For more information, see the HP 3D DriveGuard software Help.
Using Disk Defragmenter
As you use your computer over time, the files on the hard drive become fragmented. A fragmented
drive means data on your drive is not contiguous (sequential) and, because of this, the hard drive
works harder to locate files, thus slowing down the computer. Disk Defragmenter consolidates (or
physically reorganizes) the fragmented files and folders on the hard drive so that the system can run
more efficiently.
NOTE:It is not necessary to run Disk Defragmenter on solid-state drives.
After you start Disk Defragmenter, it works without supervision. However, depending on the size of your
hard drive and the number of fragmented files, Disk Defragmenter may take more than an hour to
complete.
HP recommends defragmenting your hard drive at least once a month. You may set Disk Defragmenter
to run on a monthly schedule, but you can defragment your computer manually at any time.
52 Chapter 8   Maintaining your computer 
						

							To run Disk Defragmenter:
1.Connect the computer to AC power.
2.From the Start screen, type disk, select Settings, and then select Defragment and optimize
your drives.
3.Follow the on-screen instructions.
For additional information, access the Disk Defragmenter software Help.
Using Disk Cleanup
Disk Cleanup searches the hard drive for unnecessary files that you can safely delete to free up disk
space and help the computer run more efficiently.
To run Disk Cleanup:
1.From the Start screen, type disk, select Settings, and then select Free up disk space by
deleting unnecessary files.
2.Follow the on-screen instructions.
Updating programs and drivers
HP recommends that you update your programs and drivers on a regular basis to the latest versions.
Updates can resolve 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, older graphics components might not work well with the most recent gaming
software. Without the latest driver, 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 external devices 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 or shipping your computer
If you have to travel with or ship your computer, here are some tips to keep in mind to keep your
equipment safe.
●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.
◦Shut down 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 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
54 Chapter 8   Maintaining your computer 
						

							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.

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.
56 Chapter 9   Securing your computer and information 
						

							●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, from the Start
screen, type h, and then select Help and Support.

							Your changes take effect when the computer restarts.
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.
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. It is strongly recommended that you use
the antivirus program of your choice in order to fully protect your computer.
For more information about computer viruses, from the Start screen, type support, and then select the
HP Support Assistant app.
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, Windows, and third-party software installed on your computer should be regularly updated to
correct security problems and improve software performance. For more information, see 
Updating
programs and drivers on page 53.
58 Chapter 9   Securing your computer and information
