Chapter 1. IBM PC overview

Thank you for selecting an IBM PC computer. Y o ur compu ter incorpor ates man y
of the latest advances in comp uter technology and can be u pgraded as your needs
change.

This section provides an overview of the computer features, preinstalled
software, and specifications.

Identifying your computer

The best way to identify your computer is through use of your machine type
number, configuration identification (Config. ID) number, and serial number,
which is located at the bottom of the rig ht side panel as shown in the illustration
below .

Arranging your workspace

To get the most from your computer, arrange both the equipment you use and
your work area to suit your needs and the kind of work you do. Your comfort is
of foremost importance, but light sources, air circulation, and the location of
electrical outlets also can affect the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, the following
guidelines will help you find a position that suits you best. Choose a good chair
to reduce the frequency of fatigue from sitting in the same position for a long
time. The backrest and seat should adjust independently and provide good
support. The seat should have a curved front to relieve pressure on the thighs.

Adjust the seat so that your thighs are parallel to the floor and your fee t are either
flat on the floor or on a footrest.

When using the keyboard, keep your forearms parallel to the floor and your
wrists in a neutral, comfortable position. Try to keep a light touch on the
keyboard and your hands and fingers relaxed. You can change the angle of the
keyboard for maximum comfort by adjusting the position of the keyboard feet.

Viewing Distance

Lower
Back
Support

Seat
Height

Adjust the monitor so th at the top of the screen is at, or slightly below, eye level.
Place the monitor at a comfortable viewing distance, usually 51 to 61cm (20 to
24 in.), and position it so that you can view it without having to twist your body.

2 IBM PC User Guide

Glare and lighting

Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Place the monitor at right angles to windows
and other light sources whenever possible. Reduce overhead lighting, if
necessary, by turning off lights or using lower wattage bulbs. If you install the
monitor near a window, use curtains or blinds to block the sunlight. You might
have to adjust the Brightness and Contrast controls on the monitor as the room
lighting changes throughout the day. Where it is impossible to avoid reflections
or to adjust the lighting, place an antiglare filter over the screen. However, these
filters might affect the clarity of the image on the screen; try them only after you
have exhausted other methods of reducing glare.

Dust buildup compounds problems associated with glare. Remember to clean
your monito r sc reen peri o di cally us i ng a s oft clot h moi s te ned wit h a no nabrasive
liquid glass cleaner.

Air circulation

Your computer and monitor produce heat. The computer has a fan that pulls in
fresh air and forces out hot air. The monitor lets hot air escape through vents.
Blocking the air vents can cause overheating, which might result in a malfunction
or damage. Place the computer and monitor so that nothing blocks the air vents;
usually, 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air is
not blowing on som eone else.

Electrical outlets and cable lengths

The location of electrical outlets and the length of power cords and cables that
connect to the monitor, printer, and other devices might determine the final
placement of your computer.

When arranging your workspace:

• Avoid the use of extension cords. Whenever possible, plug the computer

power cord directly into an electrical outlet.

• Keep power cords and cables neatly routed away from walkways and other

areas where they might be kicked accidentally.
For more information about power cords, See “Power cord notice” on page 58.

for the computer, monitor, and any other devices. Select a location for the
computer where it will remain dry. Leave about 50 mm (2 in.) of space around
the computer for proper air circulation.

Shutting down

When you are ready to turn off your computer, follow the shutdown procedure
for your operating system. This prevents the loss of unsaved data or damage to
your software programs. See your operating system documentation for
instructions.

Using diskettes

You can use 3.5-inch diskettes in the diskette drive of your computer. The
information that follows will help you use 3.5-inch diskettes.

Handling and storing diskettes

Inside the protective diskette case is a flexible disk with a magnetic-sensitive
coating. This disk can be damaged by heat, dust, a magnetic field, or even a
fingerprint. Use the following guidelines when handling and storing diskettes:

• Data is stored on the magnetic surface of the diskette. This surface is
protected by a plastic cover. If the cover is damaged, do not use the diskette.
A damaged diskette might damage the diskette drive.

• A protective slide on the top of a 3.5-inch diskette covers part of the
magnetic surface. The diskette drive moves this slide to read data from or
write data to the diskette. Do not move this slide because fingerprints and
dust can cause loss of data.

• Never touch the magnetic disk itself.

12 IBM PC User Guide

• Keep diskettes away from magnets or devices that create a strong magnetic
field, such as electric motors and generators. Diskettes are sensitive to
magnets found in television sets, telephon es, stereo speak ers, and other such
items. A magnetic field can erase the data on your diskettes. Do not set
diskettes on the monitor or use magnets to attach notes to your computer.

• Do not store diskettes at high temperatures, low temperatures, or in direct
sunlight. Temperatures ranging from 4° to 53°C (39° to 127°F) are
acceptable for 3.5-inch diskettes. K eep diskettes aw ay f rom heat. The plastic
outer covering might warp, damaging the diskette.

Inserting and removing diskettes

To insert a 3.5-inch diskette, hold the diskette with the label facing up and insert
the end with the protective slide first. Push the diskette into the diskette drive
until the diskette clicks into place.

To remove the diskette, press the eject button and slide the diskette out of the
drive. Do not remove the diskette while the in-use light is on .

Write-protecting diskettes

It is possible to accidentally format a diskette or unintentionally write data to it.
Important information can be written over or lost. For this reason, it is a good
idea to write-protect important diskettes. You can read data from a write­protected diskette, but you cannot erase or change the data.

Most 3.5-inch diskettes have a write-protect switch that can be used to prevent
data from being written to or erased from the diskette. If a 3.5-inch diskette does
not have a write-protect switch, it is permanently write-protected.

The write-protect switch is located on the back of 3.5-inch diskettes.

Write-protect

• To allow writing to the diskette, slide the switch so the write-protect window
is covered.

switch

Chapter 3. Operating and caring for your computer 13

• To prevent writing to the diskette, slide the switch so the write-protect
window is open.

Using a CD-ROM drive

Some models have a preinstalled CD-ROM driv e. Thi s may be a bas ic CD-ROM
(read only) drive, a CDR (recordable) drive, or a DVD (digital video) drive,
depending on the type you chose. All types of CD-ROM drives use industry
standard, 12 cm (4.75-inch) CDs.

Follow these guidelines when using a CD-ROM drive:

• Do not place the drive where there is:

- High temperature

- High humid ity

- Excessive dust

- Excessive vibration or sudden shock

- An inclined surface

- Direct sunlight

• Do not insert any object other than a CD into the drive.

• Before moving the computer, remove the CD from the drive.

Handling a CD

When handling a CD, follow these guidelines:

• Hold the CD by its edges. Do not touch the surface of the side that is not
labeled.

• To remove dust or fingerprin ts, wipe the CD with a clean, soft cloth fro m the
center to the outside. Wiping the CD in a circular direction might cause loss
of data.

• Do not write or stick paper on the CD.

• Do not scratch or mark the CD.

• Do not place or store the CD in direct sunlight.

• Do not use benzene, thinners, or other cleaners to clean the disk.

• Do not drop or bend the CD.

you with the ability to record and play back sound and music and to enjoy sound
with multimedia applications. Additionally, you can connect stereo speakers to
the line-out connector to enjoy better soun d with multimedia applications.

The audio connectors in your computer are 3.5 mm (1/8-in.) mini-jacks. A
description of the connectors follows. (For the location of the connectors, see
“Cable connections and switch settings” on page 6.)

Line/Headphone out

This jack is used to send audio signals from the computer to external devices,
such as powered stereo speakers with built-in amplifiers, headphones,
multimedia keyboards, or the audio line-in jack on a stereo system.

Chapter 4. Installing options

You can expand the capabilities of your computer by adding memory, drives, or
adapters. When adding an option, use these instructions along with the
instructions that come with th e option.

Attention

• Before you install or remove any option, read the “Safety information”
on page v. These precautions and guidelines will help you work safely.

• The presence of 5 V standby power might result in damage to your
hardware unless you disconnect the po wer cord from the electrical outlet
before opening the computer cover.

Handling static-sensitive devices

Static electricity, although harmless to you, can seriously damage computer
components and options.

When you add an option, do not open the static-protecti ve pack age containing the
option until you are instructed to do so.

When you handle options and other computer components, take these
precautions to avoid static electricity damage:

• Limit your movement. Movement can cause static electricity to build up
around you.

• Always handle compo nents carefully. Handle adapters and memory modules
by the edges. Never touch any exposed circuitry.

• Prevent others from touching components.

• When you install a new option, touch the static-protective package
containing the option to a metal expansion-slot cover or other unpainted
metal surface on the computer for at least two seconds. This reduces static
electricity in the package and your body .

• When possible, remove the option and install it directly in the computer
without setting the option down. When this is not possible, place the static­protective package that the option came in on a smooth, level surface and
place the option on it.

• Do not place the option on the computer cover or other metal surface.

Memory problems

Memory problems Action

The amount of memory
displayed is less than the
amount of memory
installed.

The amount of available memory shown might
be somewhat less than expected because basic
input/output system (BIOS) shadowing takes
some random access memory (RAM) and ACPI
and USB can take up to 1MB.

In addition, this system features an integrated
video system in which some memory is used by
the video controller. Windows will only report
the memory available for its use. F o r example, if
the system uses 4MB of memory for video and
the total system memory is 64MB, Windows will
report 60MB.

Verify that:

1. You have installed the correct type of
DIMMs for your computer. See “Working
with memory” on page 23 for instructions
on adding DIMMs.

2. The DIMMs are properly installed and
securely connected.

3. If you added or remov ed memory, you saved
the new conf i gur ati o n before exiting the

some configuration (.CFG) files or diagnostic (.EXE or .COM) files from the
diskette to your hard disk. See the docu mentation that comes with the option to
determine if you need to install files.

Replacing the battery

Your computer has a special type of memory that maintains the date, time, and
settings for built-in features, such as serial and parallel port assign ments
(configuration). A battery keeps this information active when you turn off the
computer.

The battery requires no charging or maintenance throughout its life; however, no
battery lasts forever. If the battery fails, the date, time, and configuration
information (including passwords) are lost. An error message is displayed when
you turn on the computer.

See “Lithium battery notice” on page vii for information about replacing and
disposing of the battery.

If you replace the original lithium battery with a heavy-metal battery o r a battery
with heavy-metal components, be aware of the following environmental
consideration. Batteries and accumulators that contain heavy metals must not be
disposed of with normal d omestic waste. They will be taken back free of charge
by the manufacturer, distributor, or representative, to be recycled or disposed of
in a proper manner.

To change the battery:

1. Turn off the computer and all attached devices.

2. Unplug the power cord and remove the cover. See “Removing the side
panel” on page 21.

3. Locate the battery.

4. If necessary, remove any adapters that impede access to the battery. See
“Installing adapters” on page 25 for more information.

Chapter 5. Technical Troubleshooti ng 45
