System Setup
Setting up your system
Follow the instructions on the poster that came with your system for assembly
instructions. You can prepare a safer working environment before assembling
your system by following the guidelines listed below.
■ Provide a clean, flat, stable surface for your system. Allow at least
12 inches at the back of the computer for cabling and air circulation.
■ Obtain a grounded (three-prong) AC surge-protected power strip. A
surge-protected power strip helps protect against AC line spikes.
■ Protect your system from extreme temperature and humidity. Do not
expose your system to direct sunlight, heater ducts, or other
heat-generating objects.
■ Keep your computer away from equipment that generates magnetic
fields, such as unshielded stereo speakers. Even a telephone placed too
close to the computer may cause interference.
■ Plug the computer into a wall outlet or power strip that is easily
accessible. When you turn off the computer with the power button, some
electricity still flows through the computer. To remove all power from
the computer, you need to unplug it.

Static electricity precautions
Static electricity can permanently damage electronic components in your
computer. When opening your computer case, always perform the following
procedure.
CautionPrevent electrostatic damage to your computer by
following static electricity precautions every time you open
your computer case.
To avoid static electricity discharge:
1 Wear a grounding wrist strap (available at most electronics stores).
2 Turn off the computer power.
3 Discharge any static electricity by touching a bare metal surface on the
back of the case.
4 Unplug all power cords from AC outlets and disconnect the modem cable
(if installed).
3
Static electricity precautions17
Follow these precautions to avoid electrostatic damage to your system
components:
■ Avoid static-causing surfaces such as plastic and packing foam in your
work area.
■ Remove the parts from their antistatic bags only when you are ready to
use them. Do not lay parts on the outside of antistatic bags since only
the inside of the bags provides antistatic protection.
■ Always hold cards by their edges and their metal mounting brackets.
Avoid touching components on the cards and the edge connectors that
connect to expansion slots.
■ Never slide cards or other parts over any surface.
WarningAvoid exposure to dangerous electrical voltages and
moving parts by turning off your computer. Unplug the
power cord and modem cord before r emoving the
computer cover.

Managing Your
System
Protectingagainst power source
problems
Surge suppressors, line conditioners, and uninterruptible power supplies (UPS)
can help protect your system against power source problems.
Surge suppressors
During a power surge, the voltage level of electricity coming into your system
can increase far above normal for a few milliseconds. This may cause data to
be lost or the system may be damaged as a result. To protect against power
surges, use a surge suppressor. The surge suppressor absorbs voltage surges and
prevents them from reaching your system.
A surge suppressor plugs directly into an electrical outlet. You should connect
your computer, monitor, and other devices to the surge suppressor.
If you have a modem, make sure your surge suppressor has jacks for the
telephone and modem cables. Power surges can pass through telephone wires
as well as electrical wires.
6
Protecting against power source problems69
When purchasing a surge suppressor:
■ Make sure the surge suppressor meets the appropriate product safety
certification for your location, such as Underwriters Laboratories (UL).
■ Check the maximum amount of voltage the suppressor allows to pass
through the line. The lower the voltage that the suppressor allows to pass
through, the better the protection for your system.
■ Check the energy absorption, or dissipation, rating. The higher the energy
absorption rating, the better the protection for your system.
■ Check for line-conditioner capabilities. A line conditioner smooths out
some of the normal line noise (small voltage fluctuations) of an electrical
supply.
Line conditioners
A line conditioner protects your system from the small daily fluctuations in
voltage from an electrical supply. Most systems can handle this variation, or
line noise, without problems. However, some electrical sources include more
line noise than normal. Line noise can also be a problem if your system is
located near, or shares a circuit with, a device that causes electromagnetic
interference, such as a television or a motor.
Some surge suppressors and uninterruptible power supplies include simple
line-conditioning capabilities.
Uninterruptiblepower supplies
You may lose data during a total power failure. A standby Uninterruptible
Power Supply (UPS) uses a battery to keep your system running during a power
failure. The UPS enables you to shut down your system normally, but not run
the system for an extended time.
If you purchase a standby UPS, make sure the UPS includes surge suppression
and line-conditioning features.
70Managing Your System
Maintaining and managing your hard
drive
Regular maintenance can keep your hard drive operating efficiently, and good
file management can keep your system free of unwanted files while making
important files secure and easier to find.
Harddrive maintenance utilities
By regularly using the utilities available with many operating systems, you
can help maintain the performance of your hard drive. Examples include:
■ ScanDisk
■ Check Disk
■ Disk Defragmenter
Refer to the software documentation or visit the online help system of your
operating system for specific utilities available and instructions on their use.
Checking for bad sectors and other disk problems
Bad sectors are parts of a hard drive or diskette that will not hold data. A lost
allocation unit is a group of sectors that has lost its place in the table that
the operating system uses to locate files. Utilities such as ScanDisk and Check
Disk check the hard drive for bad sectors or lost allocation units and let you
fix them.
Use this type of utility from once a week to once a month, depending on
how often you use your system. Also use them if you have any hard drive
problems.
Using adisk defragmenter to improve efficiency
When working with files, Windows may divide the files into pieces and store
the pieces at different places on the hard drive. This division of files, called
fragmentation, is normal. However, to access a file, the hard drive must search
for the pieces of the file and put the file back together, which can slow down
your system.
A disk defragmenter brings all the separate pieces back together. Defragment
your computer frequently to improve system performance.
Maintaining and managing your hard drive71
Hard drive management practices
By deleting unneeded files from your hard drive and managing the space that
is automatically allocated for saving certain files, you can help maintain the
performance of the hard drive.
Checkingharddrive space
In Windows, you can see a chart of the available hard drive space.
To check hard drive space:
1 Double-click the My Computer icon on the desktop. The My Computer
window opens.
2 Click the drive you want to check.
3 Select File, then Properties. The drive’s properties window opens. The
General tab shows you the available and used space on the drive.
Backingupfiles
Regularly backing up your files protects you from losing data and lets you
keep fewer files on your hard drive. Back up old files to a network drive or
tape drive and delete the files from your hard drive. You can use the software
that came with your tape backup drive or your large capacity disk drive to
back up the files.
You can also back up files by running the backup utility that came with your
operating system. Refer to the software documentation or visit the online help
system of your operating system for specific instructions on backing up your
files.
Deletingunneeded files
By deleting unneeded files from the hard drive, you free up space on the hard
drive and help improve hard-drive performance. The following sections give
you some simple ways to delete unneeded files.
Deleting Windows temporary files
During normal operation, Windows constantly creates new temporary (.tmp)
files. You can safely delete all but the most recent temp files. Windows will
not delete a .tmp file if the file is currently in use.
72Managing Your System
To delete .tmp files:
1 Open Explorer, select Tools, then Find, then Files and Folders.
2 At Named, type *.tmp
3 In the Look in drop-down list, select your drive letter.
4 Click Find Now. The list of .tmp files is generated.
5 Click Modified above the list. To see the Modified button, you may need
to maximize the Find window.
The list is sorted by date.
6 Highlight all the files in the list except those with today’s date.
7 Press DELETE.
Deleting temporary Internet files
As you visit Web sites, your browser stores temporary Internet files on your
hard drive in a memory cache and a disk cache. Files in the memory cache are
removed when you turn off your computer. Files are saved in the disk cache
until the space designated for the cache is full. See your browser’s Help files
for instructions on emptying the disk cache.
You can save space on the hard drive by decreasing the size of the Internet
disk cache. See your browser’s Help files for instructions.
Emptying the Recycle Bin
In Windows, when you delete a file from your hard drive it is not immediately
removed from the hard drive. Instead, the file is moved into the Recycle Bin.
Because files are stored in the Recycle Bin and not deleted from the hard drive
immediately, you can retrieve a file that you accidentally delete from the hard
drive.
To delete all the files from the Recycle Bin, right-click the
on the desktop, then select
You can save space on the hard drive by decreasing the size of the Recycle Bin.
Empty Recycle Bin.

6 Click OK.
74Managing Your System
System integrity
Your system must be protected against electrical problems and physical
hazards such as heat, moisture, and dust. Also protect it against less obvious
hazards such as viruses.
Protecting against viruses
A virus is a program written with malicious intent for the purpose of creating
havoc in a computer system.
Viruses spread through executable files, document macros, or boot sectors.
Diskettes used in a contaminated computer can get a virus and transfer the
virus when used in another computer. A virus can also spread through files
downloaded from bulletin boards or the Internet.
Some viruses may only cause your system to beep or display messages or
images on the screen. Other viruses are highly destructive, and corrupt or erase
the contents of your files or diskettes. To be safe, never assume any virus is
harmless. Always protect your system against viruses.
To protect your system against viruses:
■ Use an anti-virus program to scan your computer regularly. Make sure
to update the program periodically to keep up with new viruses.
■ Make backup copies of all files and write-protect the diskettes. A virus
cannot infect a write-protected diskette.
■ Obtain all software from reputable sources and always scan new software
for any viruses before installing it.
■ Be cautious about files you receive in e-mail or download from a network
or the Internet. If you download a file, use your anti-virus program to
scan the directory on your computer that contains the downloaded file
before you open the file.
■ If you have doubts about the source of a Microsoft
disable the file macros before opening the file. Word and Excel are set
by default to warn you if a document you are about to open contains a
macro that might have a virus.

As you troubleshoot your system, keep the following guidelines in mind:
■ Never remove the chassis cover while the computer is turned on.
■ Do not attempt to open the monitor. Even if the monitor’s power is
disconnected, stored energy within the monitor’s components can offer
a painful or harmful shock.
■ If a peripheral, such as the keyboard, mouse, drive, or printer does not
appear to work, make sure that all connections are secure.
■ If an error message displays on the screen, write it down, word for word.
You may be asked about it when calling technical support.
■ Only qualified personnel should open the system for maintenance.
■ If you are qualified to maintain the system yourself, make sure you are
properly grounded before opening the system chassis. See “Static
electricity precautions” on page 17 for more information on preventing
electrostatic damage to the system.
