Maintenance
It is important that you keep current backups of your
important data, protect against data loss, and perform
simple maintenance of your computer to ensure that it
works at peak performance.
Creating Data Backup Discs
If you ever need to perform a system recovery, the
process deletes data and returns your system to its
factory state. Back up data before a problem occurs.
An external hard disk drive is the best way to back up
important data. Or, use CD or DVD recording (or
burning) software to create backup discs of important
information, including personal files, e-mail messages,
and Web site bookmarks.
When writing data to a backup disc, you should use
software that includes write verification functionality.
This feature compares the data on your hard disk drive
with the data copied to the backup media, ensuring
that it is an exact copy.
If you encounter recording issues with discs, try
alternate media (different types or brands). Also, use
the Windows Explorer tool to view your files and verify
that all content was copied. To open Windows
®
Explorer, right-click the Windows Start Button
and then click Explore.
,
Creating System Recovery Disks
One of the first things to do when you get a new
computer is to create system recovery discs. In the
event of a full system crash, these discs can be used to
return your system to its original factory condition.
Refer to your System Recovery documentation by
clicking the Windows Start Button and then
User Guides.
Security Updates
Keeping your system free from viruses and spyware is
just as important as backing up your files.
To check for security software updates:
1 Click the Windows Start Button, and then
click Control Panel.
2 Under Security, click Check for Updates.
3 Download and install any updates by clicking
Install Updates.
To schedule automatic security updates:
1 Click the Windows Start Button, and then
click Control Panel.
2 Under Security, click Turn automatic
updating on or off.
3 Follow onscreen instructions to schedule updates.
Reviewing Programs that Run Automatically at Startup
Set the Windows Start Menu to open only needed
software programs, to improve system speed and
performance:
1 Click the Windows Start Button, All
Programs, and then click Windows
Defender.
2 Click Tools.
3 Click Software Explorer.
4 In the Category list, select Startup Programs.
5 Select the program that you want to prevent from
running, and then click Disable.
Maintenance 1
Keeping the Computer Free of Dust and Dirt
Physical maintenance of your hardware is required to
keep components working well. This includes cleaning
keyboards, screens, and internal fans in the computer.
You might notice that your computer is getting louder
when it runs. This can be caused by dust buildup on
the inside. When dust buildup gets to a certain point,
the system can overheat, causing automatic shutdown.
Cleaning vents
Air vents keep the computer and monitor cool. To
maintain efficient air flow, keep these vents clean by
using a small battery-operated vacuum cleaner.
(A battery-operated vacuum cleaner eliminates the risk
of electric shock.)
1 Ensure the computer is off and unplugged.
2 Run the vacuum cleaner over all the vents in the
computer case.
Refer to the Upgrading and Servicing Guide to access
the inside of the computer. Locate this guide by clicking
Windows Start Button and then User Guides.
You will need:
a clean, dry, lint-free cloth
isopropyl or rubbing alcohol (optional)
small battery-operated vacuum cleaner
can of compressed air with small sprayer tube
Cleaning the computer and monitor
1 Unplug the computer from its power source.
2 Unplug the monitor from its power source.
3 Use a clean, dry cloth to dust the computer case
and the monitor case.
4 Use a clean cloth dampened with warm water to
wipe the computer case and the monitor case
clean.
5 If there is sticker residue or a spill on the computer
or monitor case, use isopropyl or rubbing alcohol
and a lint-free cloth to remove it.
3 Pay particular attention to two system vents:
top vents above the main system fan (A)—use
compressed air to thoroughly remove dust.
hard disk drive vents (B)—use compressed air
on each vent to remove dust. Access these
vents by taking off the internal PCI cover in the
computer. Refer to “Removing the Internal
Covers” in your Upgrading and Servicing
Guide.

D
NOTE: Do not use water on the monitor screen.
6 Use a clean cloth to dry the computer and
monitor case.
7 Use a clean, dry cloth to clean the monitor screen;
or, for more thorough cleaning, use an antistatic
screen cleaner and a clean cloth.

4 Remove any debris that has accumulated in and
around the computer ports (for example, the
Ethernet and USB ports).
Cleaning fans, heat sink, and inside computer
Critical components inside your computer system are
cooled by fans. The heat sink absorbs and dissipates
heat. When dust builds up on the fans and heat sink, it
creates a blanket effect, causing components to
overheat, leading to poor system performance,
automatic shutdown, or early part failure.
Refer to your Upgrading and Servicing Guide to
remove parts and access the inside of your computer.
1 Ensure the computer is off and unplugged.
If you have a rollerball mouse, clean the ball and
rollers inside:
1 Turn the mouse upside down.
2 Rotate the ball-cover ring counterclockwise to
remove the ring and release the roller ball.
3 Rinse the roller ball with soap and warm water.
4 Clean the rollers inside the mouse with a cotton
swab dampened with isopropyl alcohol.
5 After the roller ball and rollers are completely dry,
replace the ball and ball-cover ring.
2 Remove the left side of the computer.
3 Remove all the hard disk drives (C), and use
compressed air to remove dust from the fan on the
left of the disk drive area (the fan is visible only
when the drives are removed).
4 (Air-cooled systems) With the small tube attached
to the compressed air sprayer, blow dust off the
heat sink (D).
5 (Liquid-cooled systems) Blow the dust through the
radiators, from the inside out.
6 Blow off the dust from all other fans.
7 Vacuum all bottom surfaces on the computer
inside.
Cleaning the keyboard and mouse
When cleaning the keyboard keys, use a low setting
on the battery-operated vacuum cleaner, to avoid
removing key caps and springs.
1 Vacuum between the keys of the keyboard and
along the grooves.
2 Use a clean, dry cloth and isopropyl alcohol to
clean buildup on the keyboard keys and along the
keyboard edges.
Running the Disk Cleanup Program
The Disk Cleanup software program frees up space on
your hard disk drive by removing temporary and
unused files (including temporary Internet files and files
in the Recycle Bin). Either run Disk Cleanup manually,
or set it up to run automatically.
Manual disk cleanup
1 Click the Windows Start Button, All
Programs, Accessories, System Tools, and
then click Disk Cleanup.
Disk Cleanup searches for files to delete and
calculates how much disk space can be saved.
2 Place a check mark in the check box next to the
file types you want to delete.
3 Click OK, and then click Delete Files to finish
deleting the selected files.
3 Wipe the body of the mouse and the mouse cord
with cleaning wipes or a cloth and cleanser.

then click Next. Disk Cleanup may take a long
time, so select a time when the computer is on but
not in use.
7 Select Start a program, and then click Next.
8 Under Program/Script, click Browse.
9 Type cleanmgr.exe, click Open, and then
click Next.
10 Review the summary of the schedule that you set.
When you are done, click Finish. Disk Cleanup
will run at the time that you set.
Running the Disk Defragmenter Program
When Microsoft® Windows Vista® stores files on your
hard disk drive, it often divides them into fragments so
that they fit into the available space on the drive.
When you open a fragmented file, the process takes
more time, because it must be retrieved from more than
one place.
The Disk Defragmenter program groups the
fragmented files together on your hard disk drive to
improve computer performance. This does not affect
the location of files and folders on your computer.
NOTE: The Disk Defragmenter program may take a
long time to complete. You can run it unattended
overnight.
1 Save your work and close all open programs.
2 Press the Ctrl, Alt, and Delete keys simultaneously.
3 Click Start Task Manager.
4 On the Applications tab, select all the programs
that are listed, and then click End Task. Close the
Task Manager.
5 Click the Windows Start Button, All
Programs, Accessories, System Tools, and
then click Disk Defragmenter.
6 Click Defragment Now.
If Disk Defragmenter repeatedly starts, a background
program is still accessing the hard disk drive. Restart
the computer in Safe Mode, and then run the Disk
Defragmenter program again:
1 Click the Windows Start
Button, click the Arrow button
next to the Lock button, and then click Restart.
2 As soon as the first logo screen appears, press the
F8 key.
3 In the Windows Advanced Options menu, use the
arrow keys to select Safe Mode, and then press
Enter.
4 After Windows Vista starts, use the preceding
procedure to run the Disk Defragmenter program.
4 Troubleshooting and Maintenance Guide
5 To turn off Safe Mode, repeat step 1.
Checking for Hard Disk Drive
Understanding Hard Disk Drive
Errors
Perform the following procedure to check the integrity
of the hard disk drive in Windows Vista. Close all
open programs before beginning the disk check.
1 Click the Windows Start Button, and then
click Computer.
2 Right-click the hard disk drive that you want to
check, and then click Properties.
3 Click the Tools tab.
4 Under Error-checking, click Check Now.
5 If desired, place a check mark in the
Automatically fix file system errors and
Scan for and attempt recovery of bad
sectors check boxes.
6 Click Start. If you are prompted to restart the
computer, click Yes.
The computer will restart and check the hard disk
drive for errors.
Space
The hard disk drive on the Hewlett-Packard and
Compaq computers with the Windows Vista operating
system preinstalled may appear to be smaller than
what is stated in the product specifications, in the
documentation, or on the box. Hard disk drives are
described and advertised by manufacturers in terms of
decimal (base 10) capacity. Windows Vista and other
programs, such as FDISK, use the binary (base 2)
numbering system.
In decimal notation, one megabyte (MB) is equal to
1,000,000 bytes, and one gigabyte (GB) is equal to
1,000,000,000 bytes. In the binary numbering
system, one megabyte is equal to 1,048,576 bytes,
and one gigabyte is equal to 1,073,741,824 bytes.
Because of the different measuring systems, you may
see a difference between the size reported by
Windows Vista and the size advertised. The storage
capacity of the hard disk drive is as advertised.
Windows Vista reports smaller capacity in the
Windows Explorer tool and in the Computer window,
because it shows information about one partition on
the hard disk drive at a time. One of the partitions
contains the system recovery information.
