SAFETY AND REGULATORY
NOTICES
General
Electrical
The computer uses a safety ground and must be earthed.
The system unit AC power cord is its ‘disconnect device’. Ensure that the
system unit is positioned close to the AC power outlet and that the plug is
easily accessible.
The power cord packed with the computer complies with the safety
standards applicable in the country in which it is first sold. Use only this
power cord. Do not substitute a power cord from any other equipment.
To prevent fire and electric shock, do not expose any part of the computer
to rain or moisture. Turn off the computer and unplug all power cords
before moving or cleaning the system unit, or removing the system unit covers.
Battery
This product contains a lithium battery.
Do not use a metal or other conductive implement to remove the battery.
If a short-circuit is made between its positive and negative terminals the
battery may explode.
Replace a discharged battery with one of the same type; another type may
explode or ignite. Follow the instructions contained in the Owner’s
Handbook to replace the battery. Dispose of a discharged battery promptly
and in accordance with the battery manufacturer’s recommended
instructions. Do not recharge, disassemble or incinerate the discharged
battery. Keep away from children.
Laser products
Any CD-ROM drive fitted in this system is classified as a CLASS 1 LASER
PRODUCT according to IEC825 Radiation Safety of Laser Products
(Equipment Classification: Requirements and User's Guide). The CLASS 1
LASER PRODUCT label is located on the underside of the system unit.
The CD-ROM drive contains a laser system which is harmful to the eyes if
exposed. Do not attempt to disassemble the CD-ROM drive; if a fault
occurs, call an authorised maintainer.
i
Safety & regulatory notices
Use the CD-ROM drive only as described in this manual. Failure to do so
may result in exposure to hazardous radiation.
Ergonomic
When positioning the system unit, monitor and keyboard, take into
account any local or national regulations relating to ergonomic
requirements.
Anti-static precautions
WARNING
Static electricity can cause permanent damage to electronic components.
You should be aware of this risk, and take precautions against the
discharge of static electricity into the computer.
The computer is at risk from static discharge while any of the covers are
off. This is because the electronic components of the motherboard are
exposed. Memory modules, expansion cards and replacement processors
are examples of electrostatic sensitive devices (ESSDs).
All work that involves removing the cover must be done in an area
completely free of static electricity. We recommend using a Special
Handling Area (SHA) as defined by EN 100015-1: 1992. This means that
working surfaces, floor coverings and chairs must be connected to a
common earth reference point, and you should wear an earthed wrist strap
and anti-static clothing. It is also a good idea to use an ionizer or
humidifier to remove static from the air.
When installing any upgrade, be sure you understand what the installation
procedure involves before you start. This will enable you to plan your
work, and so minimise the amount of time that sensitive components are
exposed.
Do not remove the system unit cover, nor the anti-static bag or wrapping
of any upgrade, until you need to.
Handle static-sensitive items with extreme care. Hold expansion cards and
add-on components only by their edges, avoiding their electrical contacts.
Never touch the components or electrical contacts on the motherboard or
on expansion cards. In general, do not handle static-sensitive items
unnecessarily.
Keep all conductive material, and food and drink, away from your work
area and the open computer.
Thermalcote bonding compound
The thermal bonding compound used between the system processor and
its heat sink can cause skin irritation and stain clothing. Avoid prolonged
ii
Safety & regulatory notices
or repeated contact with skin. Wash thoroughly with soap and water after
handling. Avoid contact with eyes and inhalation of fumes. Do not ingest.
Maintenance
Switch off and disconnect all cables before attempting to clean the
computer.
Do not use sprays, solvents or abrasives that might damage the system unit
surface. Do not use cleaning fluids or sprays near air vents, ports, or the
diskette and CD-ROM drives.
Occasionally wipe the system unit with a soft, slightly damp, lint-free
cloth.
Occasionally wipe over the air vents on the rear and sides of the system
unit. Dust and fluff can block the vents and limit the airflow.
Occasionally clean the diskette and CD-ROM drives using a proprietary
head cleaner.
Occasionally wipe the monitor with a soft, slightly damp, lint-free cloth. It
is best to use anti-static glass cleaner on the monitor screen, but do not
spray glass cleaner directly onto the screen; it could run down inside the
case and damage the circuitry.
Transporting
Use common sense when handling the computer; hard disks in particular
can be damaged if the computer is dropped or handled roughly. As a
precaution, back up the contents of the hard disks to tape or diskettes
before moving the computer.
Switch off and disconnect all cables before attempting to move the
computer, In particular, do not try to move the computer while it is
plugged into the AC power supply.
When lifting and carrying the computer, use the metal sides of the system
unit and never attempt to lift the system unit with a monitor still on top.
If you need to transport the computer any great distance, use the original
packing materials.
If you are planning to use the computer in another country, it may not be
suitable, check with your supplier, particularly on the availability of the
correct AC power cords.
NOTE
Any existing maintenance or warranty agreement may not be supportable in
another country. The system may have to be returned to the supplier.

SYSTEM MOTHERBOARD
This chapter describes the features of the system
motherboard, setting jumpers and other relevant
information.
Microprocessor
This motherboard supports 233 MHz, 266 MHz and 300
MHz Intel Pentium II processors with MMX technology
and 512 KB secondary (L2) cache.
The Pentium II processor is packaged in a Single Edge
Contact (S.E.C.) cartridge that mounts in the Slot 1
processor connector on the motherboard.
Main Memory (SDRAM)
The motherboard supports up to 384MB of SDRAM.
SDRAM is implemented through three 168-pin DIMM
sockets. The motherboard contains three DIMM sockets. To
add memory to the motherboard, see Chapter 4. For the
motherboard’s main memory map, see the ‘Motherboard
Resources’ section later in this chapter.
Memory error checking and correction is supported with
parity or ECC DIMMs. Parity or ECC DIMMs are
automatically detected. However, For ECC operation to be
available, all installed memory must be ECC and the user
must enter Setup to configure DIMMs for either parity or
ECC operation. Parity memory will detect single-bit errors.
ECC memory will detect multi-bit errors and correct singlebit errors.
Errors may be generated by a defective memory module,
mixing different speed memory modules, or by DMA or
memory conflicts.

♦
Support for an IrDA or Consumer IR compatible
infrared interface. The infrared interface supports data
transfer rates of up to 115 K baud with either half- or
full-duplex operation
♦
Industry standard diskette drive controller that supports
720 KB, 1.44 MB, and 2.88 MB floppy drives (at 135
tracks per inch); and the older 360 KB and 1.2 MB drives.
BIOS Features
The BIOS, from American Megatrends Inc. (AMI), provides
ISA and PCI compatibility. The BIOS is contained in a
Flash memory device soldered to the motherboard. The
BIOS provides the POST, the Setup program, a PCI and
IDE auto-configuration utility, and BIOS recovery code. For
full information see the ‘BIOS and Setup’ chapter.
PCI Auto-configuration
The PCI auto-configuration utility works in conjunction
with the Setup program to support using PCI add-in cards
in the computer. When you turn on the power after
installing a PCI card, the BIOS automatically configures
interrupts, DMA channels, and I/O space.
3/8
LS700 HANDBOOK
System motherboard
Since PCI add-in cards use the same interrupt resources as
ISA add-in cards, you must specify the interrupts used by
ISA cards in the Setup program.
Expansion Slots
The
motherboard
has
one
dedicated
16-bit
ISA/AT-compatible and three dedicated PCI-compatible
expansion slots. Another expansion slot is a combination slot
that can be used for either a PCI or an ISA card. This allows
you to install a maximum of five add-in cards.
Real-time Clock and CMOS RAM
The I/O controller provides a real-time clock and CMOS
RAM. You can set the time for the clock and the CMOS
values by using the Setup program described in the BIOS
Chapter. This will need to be carried out if there is a
requirement to change the CMOS battery, as detailed over.
CMOS Battery
A battery on the motherboard keeps the clock and values in
CMOS RAM current when your computer is turned off.
The battery should last about seven years. When the battery
begins to die, it loses voltage; when the voltage drops below
a certain level, the Setup program settings stored in CMOS
RAM (for example, the date and time) might not be
accurate. Replace the battery with an equivalent one.
WARNING
The CMOS battery is a lithium type. Do not use a metal tool to
remove the battery. An accidental short circuit may cause the
battery to explode. Dispose of the battery according to the
battery manufacturers recommendations.
LS700 HANDBOOK
3/9
System motherboard
To replace the battery:
1.
Observe the precautions in ‘Before You Begin’
(Chapter 2).
2.
Turn off all peripheral devices connected to the
computer.
3.
Turn off the computer and unplug the power cable.
4.
Remove the computer top and access covers.
5.
With your fingers, gently pry the battery free from its
socket. Note the "+" and "-" orientation of the battery.
6.
Install the new battery in the socket, orienting the “+”
and “-” correctly.
7.
Replace the computer cover.
USB Interface Support
The USB ports permit the direct connection of two USB
peripherals without an external hub. If more devices are
required, an external hub can be connected to either of the
built-in ports. The motherboard supports the standard
universal host controller interface (UHCI) and uses standard
software drivers that are UHCI-compatible.
Features of the USB include:
3/10
♦
Support for self-identifying, hot-pluggable peripherals
♦
Automatic device configuration
♦
Support for synchronous and asynchronous transfers
over the same set of wires
♦
Support for up to 127 physical devices
♦
Bandwidth and low latencies appropriate for telephony,
audio, and other applications
♦
Error handling and fault recovery built into protocol
LS700 HANDBOOK
System motherboard
NOTE
Computers that have an unshielded cable attached to the USB
port risk causing radio frequency interference (RFI). Use
shielded cable for all devices attached to either USB port.
Speaker
A speaker is mounted on the motherboard. The speaker
provides audible error code information (beep codes) during
the POST if the BIOS cannot use the video interface. For
beep code descriptions, see Chapter 6.

TROUBLESHOOTING
This chapter offers advice if you suspect a fault with your
computer. It is concerned mainly with problems caused by
the computer itself, if there are problems with software, read
the software guide or contact the software supplier.
Make a note of any symptoms, error codes, or display
messages before calling your supplier or maintenance
provider
Problems when starting
If you suspect a blown fuse
In the United Kingdom, and some other countries, AC
plugs contain fuses. If the fuse in the AC plug blows when
you turn on the computer, this may be caused by an AC
power surge, but may be a symptom of problems with the
computer or its peripherals. Follow these steps:
1.
Turn off the computer and unplug all power cables and
unplug and disconnect all peripherals.
2.
If no cause is apparent, replace the blown fuse with one
of the same rating, reconnect the system unit power
cable and try to turn it on again.
3.
If the replacement fuse blows, call your supplier or
maintenance provider.
4.
If the replacement fuse does not blow, reconnect one
peripheral at a time and switch it on. Repeat this step
for each peripheral in turn.
Power-on self-test (POST)
Whenever the computer is turned on, the power-on self-test
(POST) routine tests hardware components, including
memory, and compares the actual configuration of the
LS700 HANDBOOK
6/1
Troubleshooting
computer with that recorded in configuration (CMOS)
memory. During this time, BIOS sign-on and POST
messages are displayed.
If POST detects a hardware fault, one or more POST error
codes and messages are displayed. Your first action should be
to turn off the computer, wait at least 30 seconds, and then
turn it on again to see if the error is transitory or persistent.
Persistent POST errors may indicate a fault in the system.
◊ Check that all external cables are securely
connected.
◊ Try running the BIOS Setup utility to reconfigure
the system.
◊ Open up the system unit and check that all internal
signal and power cables are securely connected.
If the problem persists, call your supplier or authorised
maintainer.
Failure to boot
On completion of POST, the computer attempts to boot
from a system diskette or bootable hard disk. Some of the
messages that might appear during the boot sequence:

Explanation
Fixed disk read failure
The hard disk may be defective. Press F1 to retry. Make
sure the drive is correctly specified in the BIOS setup
utility. If the problem persists, insert a system diskette,
press F1, backup the data held on the defective hard
disk and try reformatting it.
No boot device available This may indicate a fault in the diskette or hard disk
drive, or perhaps a damaged system diskette. Make sure
that the Startup Device options are correctly specified
with the BIOS Setup utility. If the problem persists
contact your supplier or authorised maintainer.
Beep Codes
The computer uses special audio beep codes to signal certain
hardware faults.
One long beep followed by several short beeps indicates a
video problem. There may be no display on the screen.

Troubleshooting
Troubleshooting Checklist
If you encounter a problem with the computer the following
sections suggest checks to make before you alert your dealer,
authorised maintainer or support organisation. The checks
listed cover the causes of common problems.
Connections
Check that all power and signal cables are securely
connected to the correct port on the computer.
The two serial ports appear identical. If you have a problem,
make sure that the cable is connected to the port you are
trying to use.
Power
Check that the AC power supply is switched on, and that
the fuse in the AC plug (if any) has not blown. If the system
still does not seem to be getting power, obtain another
power cord from your supplier.
Monitor
If there is no display check that the monitor is turned on,
and the brightness and contrast controls are not too low.
Expansion Cards
If an expansion card does not work, check that all internal
cables are securely connected, that the card is configured
correctly, that its use of system resources does not conflict
another card or motherboard component, and that legacy
resources (if it is an ISA card) are properly declared in the
BIOS setup utility.
Check also that the software which drives or uses the card is
correctly configured.

LS700 HANDBOOK
Troubleshooting
System BIOS
Check finally the system BIOS to ensure that it has not been
disturbed from the original settings. An area is provided
within Chapter 5 (System BIOS and Setup) to make a note
of your current or original BIOS settings.
If the settings appear to have altered, there may be a fault
with the CMOS battery. See Chapter 3 (System
Motherboard) and Chapter 5 (System BIOS and Setup).
The System’s Disk Drives
Floppy Disk Drive
If you have problems accessing a diskette or floppy disk,
check that it is inserted correctly, that it has been correctly
formatted, that it is not write-protected, and that the
permissions assigned by the BIOS allow the intended access.
Some application software also may not allow you to read or
write to floppy disks during certain other operations, or until
you are about to exit the programme.
Optional CD-ROM drive
If you have problems accessing a CD, check that you have
allowed a few seconds for the disk to spin up to full speed,
that the disk is the correct way up in the drive, printed side
upwards, and that it is a data CD.
Remember that with a conventional CD-ROM drive you
cannot write to a CD.
Hard Disk Drive
If you encounter problems accessing any IDE hard disk
drive, use the BIOS Setup utility to check that the drive is
correctly specified, and that the drive’s controller is enabled.
Check also that the disk has been correctly formatted, and
LS700 HANDBOOK

that the permission assigned by the operating system allow
the intended access.
SCSI Drives
If you have just fitted a new SCSI drive, or device, check
that you have used a valid ‘ID’ that does not conflict with
other SCSI drives or devices is the system. Look in any
documentation for information.
On boot up, just after POST, a list is displayed of the
devices attached to the SCSI interface, which shows the
device, its parameters and the set ‘ID’.
Error Messages
Some of these messages may indicate a serious fault with the
system and may cause the POST to halt. If the message
persists, make a note of it and call your supplier or
authorised maintainer.
PCI Configuration Error Messages
The following PCI messages are displayed as a group with
