Troubleshooting 71
Modem Problems
Problem Action
My modem doesn't connect
to services or disconnects
during communication
If your modem has difficulty in connecting to on-
line services and sustaining communications, first
check if other devices are connected and remove
them. Also remove any extension leads. Interference
from certain devices or poor line power conditions
may degrade the quality of your connection. Under
these conditions gradually reduce the
communication speed of your modem until a reliable
connection is achieved.
Check with your on-line service provider.
When using a PBX phone
system I can't dial on my
modem.
If you use a PBX phone system you may need to
press a number i.e. '9' to connect to an external line,
you should enter the following command before
trying the connection and check modem
initialization. (ATX3&W)
And add “9,” as the external line prefix (example) of
the phone number when using the dial command
“ATDT9, 123-4567”.
Screen displays random or
garbage characters during
communications.
After your modem has connected to the on-line
service, your screen may display garbage characters
or after-images in screen transitions. This problem is
caused by a mismatch of the terminal modes
between communications service and
communications programs. You need to match the
terminal modes to each other. Refer to the user's
guide of the communications program you're using.
Reports error message that
insufficient Hard Disk space
is available.
Delete the unnecessary messages or data you
received by Modem or Fax every one to three
months as required.
If you're using the internet, many picture and data
files can get downloaded to your HARD DISK every
time you visit a home page, which will consume a lot
of your HARD DISK space. For more detailed
information about the method of deleting, refer to
the help of the Web browser you've been using or
your user's guide.

Glossary
AC adapter
The AC (or alternating current) adapter regulates current coming into your
computer from the wall outlet. The current at the wall outlet is alternating current
and needs to be changed by the adapter to DC (direct current) before your
computer can use it for power.
ACPI
ACPI (Advanced Configuration and Power Interface)- a method for describing
hardware interfaces in terms abstract enough to allow flexible and innovative
hardware implementations and concrete enough to allow shrink-wrap OS code to
use such hardware interfaces.
BIOS
BIOS stands for basic input/output system. The BIOS is software (often called
firmware) that is independent of any operating system. It enables the computer to
communicate with the screen, keyboard, and other peripheral devices without
using programs on the hard disk.
The BIOS on your computer is flash BIOS, which means that it has been recorded
on a flash memory chip that can be updated if needed.
Boot
To start your computer. A cold boot resets the entire computer and runs through
all computer self-tests. A warm boot clears out computer memory only.
Boot disk
A disk containing operating system programs required to start your computer. A
boot disk can be a floppy disk, hard drive, or compact disc.
Byte
The basic unit of measure for computer memory. A character—such as a letter of
the alphabet—uses one byte of memory. Computer memory is often measured in
kilobytes (1,024 bytes) or megabytes (1,048,576 bytes).
Each byte is made up of eight bits. For more information on bytes and bits, see an
introductory book on computers.
Cache memory
Cache is very fast, zero-wait-state memory located between the microprocessor
and main memory. Cache reduces the average time required by the
microprocessor to get the data it needs from the main memory by storing recently
accessed data in the cache.

CardBus
CardBus technology enables the computer to use 32-bit PC Cards. Hardware in
the computer and the Windows operating system provide support for the 32-bit
cards. The voltage of 32-bit cards (3.3 volts) is lower than that of 16-bit cards (5
volts). The 32-bit cards can transmit more data at a time than the 16-bit cards, thus
increasing their speed.
CMOS memory
CMOS (complementary metal oxide semiconductor) memory is powered by the
CMOS battery. The System Setup settings and other parameters are maintained in
CMOS memory. Even when you turn your computer off, the information in
CMOS memory is saved.
COM port
COM stands for communication. COM ports are the serial ports in your computer.
Compact Disc
A compact disc (CD).
Conventional memory
The first 640 KB of system memory. Operating systems and application programs
can directly access this memory without using memory-management software.
Disk
The device used by the computer to store and retrieve information. Disk can refer
to a floppy disk, hard disk, or RAM disk.
Disk cache
A software device that accumulates copies of recently used disk sectors in RAM.
The application program can then read these copies without accessing the disk.
This, in turn, speeds up the performance of the application.
A cache is a buffer for transferring disk sectors in and out of RAM. Data stored in
a disk cache is a copy of data already stored on the physical disk.
DMA (direct memory access)
A method of transferring data from a device to memory without having the data
pass through the microprocessor. Using DMA can speed up system performance.
DPMS
Display Power Management Signalling. Displays or monitors that comply with
this can be managed by the Power Management features found in the system
setup.
Floppy disk
A removable disk, also called floppy or diskette.

Hard drive
Also called fixed disk. A hard drive is connected to the computer and can be
installed or removed. Data written to a hard drive remains until it is overwritten
or corrupted.
The 2.5-inch hard drive in your computer was designed for use in a notebook
computer. Because hard drives in notebook computers are smaller than those in
desktop computers, their maximum storage capacity may be less than that of
desktop hard drives. However, because of their smaller size, the drives handle
shock and vibration better than larger drives, which is important for a notebook
computer.
I/O
Input/output. Refers to peripheral devices, such as printers, that are addressed
through an I/O address.
I/O address
I/O stands for input/output. Peripheral devices, such as printers, are addressed
through the I/O port address.
IRQ (interrupt request line)
The IRQ is a hardware line that a device uses to signal the microprocessor when
the device needs the microprocessor’s services. The number of IRQs is limited by
industry standards.
LCD (liquid-crystal display)
The LCD screen on your computer differs from the display screen of a desktop
monitor. Most desktop monitors use CRT (cathode-ray tube) displays, which
work by moving an electron beam across phosphor dots on the back of the screen.
The phosphor dots light up to show the image. LCDs use a liquid-crystal solution
between two sheets of polarizing material. Electric current passing through the
liquid aligns the crystals so that light can or cannot pass through them, creating an
image.
MB (megabyte)
1,024 kilobytes.
Megabit
1,048,576 bits or about 128 kilobytes.
Operating system
A program that supervises the computer's operation, including handling I/O.
Application programs and users can request operating-system services. A user
might request operation-system services to copy files or format a disk. An
application program might use the operating system to obtain keyboard input,
write data to a file, or write data to a screen.

PC Card
PC Card stands for personal computer card. The Personal Computer Memory
Card International Association (PCMCIA) defines the standards used to develop
all PC Cards. PC Card types include: modems, Ethernet adapters, SCSI adapters,
ATA cards, and memory cards.
PC slot
The PC slot is the hardware slot in the computer where the PC Card is placed.
Pixel
A pixel is an individual dot in a graphic displayed on your computer. The pixels
are so close together that they look as though they are connected. An LCD screen
displays thousands or millions of pixels.
Plug and Play
A plug and play operating system automatically configures computer components
to work with your system. With this type of operating system, you normally do
not need to set jumpers on devices or set memory addresses or IRQs.
RAM (random access memory)
The computer's system memory, including conventional and extended memory.
You can write to and read from RAM. Information stored in RAM is temporary,
and is erased when the system is turned off.
Refresh rate
The refresh rate is the rate at which the image on the LCD screen is rewritten to
the screen. A fast refresh rate helps keep the image from flickering.
Resolution
The resolution is the sharpness or clarity of the image on your LCD screen.
Resolution is measured by the number of pixels the computer’s screen can
display. For example, a resolution of 800 x 600 means that the screen can display
800 pixels in row and can display 600 rows. The more pixels displayed, the higher
the resolution and the better the image.
ROM (read-only memory)
Permanent computer memory dedicated to a particular function. For example, the
instructions for starting the computer when you first turn on power are contained
in ROM. You cannot write to ROM. (ROM is not the same as RAM).
Sector
Also known as disk sector. The portion of a track that is numbered and can hold
a specified number of characters (usually 512 KB).

Shadow RAM
A write-protected area of RAM that contains a copy of the BIOS. As the computer
boots, the BIOS is copied from its permanent location in ROM to RAM. The
BIOS can be executed much faster in RAM than in ROM. The BIOS remains in
shadow RAM until you turn off the computer.
TFT (thin film transistor) LCD
A TFT LCD uses a separate transistor circuit to control each pixel. This
technology provides the best resolution for an LCD screen. A TFT LCD is also
sometimes called an active matrix LCD.
Zoomed video
Zoomed video technology enables zoom video PC Card to transfer data directly
from the card to video and audio systems without going through the
microprocessor. This process improves video performance. Video conferencing
and real-time multimedia devices, such as video cameras, are supported by zoom
video.
