Before using this information and the product it supports, be sure to read the general information under
“Appendix A. Important safety instructions” on page 41 and “Appendix B. Product warranties and notices” on
page 47 .
DANGER
v To avoid electric shock hazard, connect and disconnect cables appropriately when installing, moving or opening
the covers of this product or attached devices. Use the power cord with a properly grounded outlet.
v Do not leave the base of your computer in contact with your lap or any part of your body for an extended
period when the computer is functioning or when the battery is charging. Your computer dissipates some heat
during normal operation. This heat is a function of the level of system activity and battery charge level.
Extended contact with your body, even through clothing, could cause discomfort or, eventually, a skin burn.
v To reduce the risk of electric shock, do not use your computer in or near water.
v To avoid electric shock, do not use your computer with the telephone cable connection during an electrical
storm. Do not connect the cable to or disconnect it from the telephone outlet on the wall during an electrical
storm.
v Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags.
v The battery pack contains a small amount of harmful substances. There is danger of an explosion if the battery
pack is incorrectly replaced, exposed to fire or water, short-circuited or disassembled. Keep the battery pack
away from children and do not put it in trash that is disposed of in landfills.
v To reduce the risk of fire, use only No. 26 AWG or thicker telephone cable.
v The fluorescent lamp in the LCD contains mercury. Do not put it in trash that is disposed of in landfills. Rough
handling or dropping the computer can cause the LCD to break and the internal fluid to get into your eyes or
on your hands. Immediately wash the affected areas with water. If symptoms persist, seek medical care.
v Do not open the CD-ROM or DVD drive unit, as this might result in hazardous radiation exposure.
v Avoid direct eye exposure with the laser beam contained in some drives.

Chapter 1. Overview of your new ThinkPad computer
Caring for your ThinkPad computer
Caring for your ThinkPad computer
Though your computer is designed to function reliably in normal work
environments, you need to use common sense in handling it. By following
these important tips, you will get the most use and enjoyment out of your
computer.
Important tips:
Be careful about where and how you work
v Do not leave the base of your computer in contact with your lap or any
part of your body for an extended period when the computer is functioning
or when the battery is charging. Your computer dissipates some heat during
normal operation. This heat is a function of the level of system activity and
battery charge level. Extended contact with your body, even through
clothing, could cause discomfort or, eventually, a skin burn.
v Place liquids away from your computer to avoid spills, and keep your
computer away from water (to avoid the danger of electrical shock).
v Store packing materials safely out of the reach of children to prevent the
risk of suffocation from plastic bags.
v Keep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13cm/5 in).
v Avoid subjecting your computer to extreme temperatures (below 5°C/41°F
or above 35°C/95°F).
Be gentle with your computer
v Avoid placing any objects (including paper) between the display and the
keyboard or under the keyboard.
v Do not drop, bump, scratch, twist, hit, vibrate, push or place heavy objects
on your computer, display, or external devices.
v Your computer display is designed to be opened and used at an angle
slightly greater than 90 degrees. Do not open the display beyond 135
degrees, as this might damage the computer hinge.
Carry your computer properly
v Before moving your computer, be sure to remove any media, turn off
attached devices, and disconnect cords and cables.
v Be sure your computer is in standby or hibernation mode, or turned off,
before moving it. This will prevent damage to the hard disk drive and data
loss.
v When picking up your open computer, hold it by the bottom. Do not pick
up or hold your computer by the display.
ThinkPad® T23 Service and Troubleshooting Guide
Caring for your ThinkPad computer
v Use a quality carrying case that provides adequate cushion and protection.
Do not pack your computer in a tightly packed suitcase or bag.
Handle storage media and drives properly
v If your computer comes with a diskette drive, avoid inserting diskettes at
an angle and attaching multiple or loose diskette labels, as these can lodge
in the drive.
v If your computer comes with a CD-ROM or DVD-ROM drive, do not touch
the surface of a CD or the lens on the CD-ROM or DVD-ROM tray.
v Wait until you hear the CD- or DVD-ROM click into the center pivot of the
CD- or DVD-ROM drive before closing the CD- or DVD-ROM tray
v When installing your hard disk, diskette, CD-ROM, or DVD-ROM drive,
follow the instructions shipped with your hardware, and apply pressure
only where needed on the device. See Access ThinkPad, your on-board help
system, for information on replacing your hard disk drive (open Access
ThinkPad by pressing the ThinkPad button).
Take care in setting passwords
v Remember your passwords. If you forget a supervisor or hard disk
password, IBM will not reset it, and you may have to replace your system
board or hard disk drive.
v If you are an administrator, remember that setting a supervisor password
can prevent unauthorized initialization.
Other important tips
v Your computer modem may use only an analog telephone network, or
public-switched telephone network (PSTN). Do not connect the modem to a
PBX (private branch exchange) or any other digital telephone extension line
because this could damage your modem. Analog phone lines are often used
in homes, while digital phone lines are often used in hotels or office
buildings. If you are not sure which kind of phone line you are using,
contact your telephone company.
v Your computer might have both an Ethernet connector and a modem
connector. If so, be sure to connect your communication cable to the correct
one, so your connector is not damaged. See Access ThinkPad, your
on-board help system, for information on the location of these connectors
(press the ThinkPad button to open Access ThinkPad).
v Register your ThinkPad products with IBM (refer to the Web page:
www.pc.ibm.com/register). This can help authorities return your computer
to you if it is lost or stolen. Registering your computer also enables IBM to
notify you about possible technical information and upgrades.
v Only an authorized IBM ThinkPad repair technician should disassemble
and repair your computer.
Chapter 1. Overview of your new ThinkPad computer
Caring for your ThinkPad computer
v Do not modify or tape the latches to keep the display open or closed.
v Take care not to turn your computer over while the ac adapter is plugged
in. This could break the adapter plug.
v Turn off your computer if you are replacing a device in a device bay, or else
verify that the device is warm- or hot-swappable.
v If you exchange drives in your computer, reinstall the plastic bezel faces (if
supplied).
v Store your external and removable hard disk, diskette, CD-ROM, and
DVD-ROM drives in the appropriate containers or packaging when they are
not being used.
Cleaning your computer
Occasionally clean your computer as follows:
v Use a soft cloth moistened with nonalkaline detergent to wipe the exterior
of the computer.
v Avoid spraying cleaner directly on the display or the keyboard.
v Gently wipe the display with a dry, soft cloth.

Diagnosing problems
If you have a problem with your computer, you can test it by using
PC-Doctor® for Windows. To run PC-Doctor for Windows, do as follows:
1. Click Start.
2. Move the cursor to Programs and then to PC-Doctor for Windows.
3. Click PC-Doctor for Windows.
4. Choose either the Quick Test or the Standard Test.
Attention
Running the Quick Test set can take 10 minutes or longer. Make sure
you have time to run the entire test; do not interrupt the test while it is
running.
The Quick Test set runs many tests of critical hardware components, but it
does not run all of the diagnostic test in PC-Doctor for Windows. If PC-Doctor
for Windows reports that all of the tests in the Quick Test set have been run
and that it has found no problems, consider running additional tests.
If you are preparing to contact IBM for support, be sure to print the test log
so that you can rapidly provide information to the help technician.

IBM Statement of Limited Warranty
Part 1 - General Terms
This Statement of Limited Warranty includes Part 1 - General Terms and Part
2 - Country-unique Terms. The terms of Part 2 replace or modify those of Part
1. The warranties provided by IBM in this Statement of Limited Warranty
apply only to Machines you purchase for your use, and not for resale, from
IBM or your reseller. The term ″Machine″ means an IBM machine, its features,
conversions, upgrades, elements, or accessories, or any combination of them.
The term ″Machine″ does not include any software programs, whether
pre-loaded with the Machine, installed subsequently or otherwise. Unless IBM
specifies otherwise, the following warranties apply only in the country where
you acquire the Machine. Nothing in this Statement of Limited Warranty
affects any statutory rights of consumers that cannot be waived or limited by
contract. If you have any questions, contact IBM or your reseller.
© Copyright IBM Corp. 2001
47
The IBM Warranty for Machines
IBM warrants that each Machine 1) is free from defects in materials and
workmanship and 2) conforms to IBM’s Official Published Specifications
(″Specifications″). The warranty period for a Machine is a specified, fixed
period commencing on its Date of Installation. The date on your sales receipt
is the Date of Installation unless IBM or your reseller informs you otherwise.
If a Machine does not function as warranted during the warranty period, and
IBM or your reseller are unable to either 1) make it do so or 2) replace it with
one that is at least functionally equivalent, you may return it to your place of
purchase and your money will be refunded.
Extent of Warranty
The warranty does not cover the repair or exchange of a Machine resulting
from misuse, accident, modification, unsuitable physical or operating
environment, improper maintenance by you, or failure caused by a product
for which IBM is not responsible. The warranty is voided by removal or
alteration of Machine or parts identification labels.
THESE WARRANTIES ARE YOUR EXCLUSIVE WARRANTIES AND
REPLACE ALL OTHER WARRANTIES OR CONDITIONS, EXPRESS OR
IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
WARRANTIES OR CONDITIONS OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE. THESE WARRANTIES GIVE
YOU SPECIFIC LEGAL RIGHTS AND YOU MAY ALSO HAVE OTHER
RIGHTS WHICH VARY FROM JURISDICTION TO JURISDICTION.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR
LIMITATION OF EXPRESS OR IMPLIED WARRANTIES, SO THE ABOVE
EXCLUSION OR LIMITATION MAY NOT APPLY TO YOU. IN THAT
EVENT, SUCH WARRANTIES ARE LIMITED IN DURATION TO THE
WARRANTY PERIOD. NO WARRANTIES APPLY AFTER THAT PERIOD.
Items Not Covered by Warranty
IBM does not warrant uninterrupted or error-free operation of a Machine.
Any technical or other support provided for a Machine under warranty, such
as assistance via telephone with ″how-to″ questions and those regarding
Machine set-up and installation, will be provided WITHOUT WARRANTIES
OF ANY KIND.
Warranty Service
To obtain warranty service for a Machine, contact IBM or your reseller. If you
do not register your Machine with IBM, you may be required to present proof
of purchase.
During the warranty period, IBM or your reseller, if approved by IBM to
provide warranty service, provides without charge certain types of repair and
48
ThinkPad® T23 Service and Troubleshooting Guide
exchange service to keep Machines in, or restore them to, conformance with
their Specifications. IBM or your reseller will inform you of the available
types of service for a Machine based on its country of installation. At its
discretion, IBM or your reseller will 1) either repair or exchange the failing
Machine and 2) provide the service either at your location or a service center.
IBM or your reseller will also manage and install selected engineering changes
that apply to the Machine.
Some parts of IBM Machines are designated as Customer Replaceable Units
(called ″CRUs″), e.g., keyboards, memory, or hard disk drives. IBM ships
CRUs to you for replacement by you. You must return all defective CRUs to
IBM within 30 days of your receipt of the replacement CRU. You are
responsible for downloading designated Machine Code and Licensed Internal
Code updates from an IBM Internet Web site or from other electronic media,
and following the instructions that IBM provides.
When warranty service involves the exchange of a Machine or part, the item
IBM or your reseller replaces becomes its property and the replacement
becomes yours. You represent that all removed items are genuine and
unaltered. The replacement may not be new, but will be in good working
order and at least functionally equivalent to the item replaced. The
replacement assumes the warranty service status of the replaced item. Many
features, conversions, or upgrades involve the removal of parts and their
return to IBM. A part that replaces a removed part will assume the warranty
service status of the removed part.
Before IBM or your reseller exchanges a Machine or part, you agree to remove
all features, parts, options, alterations, and attachments not under warranty
service.
You also agree to
1. ensure that the Machine is free of any legal obligations or restrictions that
prevent its exchange;
2. obtain authorization from the owner to have IBM or your reseller service a
Machine that you do not own; and
3. where applicable, before service is provided:
a. follow the problem determination, problem analysis, and service
request procedures that IBM or your reseller provides;
b. secure all programs, data, and funds contained in a Machine;
c. provide IBM or your reseller with sufficient, free, and safe access to
your facilities to permit them to fulfill their obligations; and
d. inform IBM or your reseller of changes in a Machine’s location.
Appendix B. Product warranties and notices
49
IBM is responsible for loss of, or damage to, your Machine while it is 1) in
IBM’s possession or 2) in transit in those cases where IBM is responsible for
the transportation charges.
Neither IBM nor your reseller is responsible for any of your confidential,
proprietary or personal information contained in a Machine which you return
to IBM or your reseller for any reason. You should remove all such
information from the Machine prior to its return.
Limitation of Liability
Circumstances may arise where, because of a default on IBM’s part or other
liability, you are entitled to recover damages from IBM. In each such instance,
regardless of the basis on which you are entitled to claim damages from IBM
(including fundamental breach, negligence, misrepresentation, or other
contract or tort claim), except for any liability that cannot be waived or
limited by applicable laws, IBM is liable for no more than
1. damages for bodily injury (including death) and damage to real property
and tangible personal property; and
2. the amount of any other actual direct damages, up to the charges (if
recurring, 12 months’ charges apply) for the Machine that is subject of the
claim. For purposes of this item, the term ″Machine″ includes Machine
Code and Licensed Internal Code.
This limit also applies to IBM’s suppliers and your reseller. It is the
maximum for which IBM, its suppliers, and your reseller are collectively
responsible.
UNDER NO CIRCUMSTANCES IS IBM LIABLE FOR ANY OF THE
FOLLOWING: 1) THIRD-PARTY CLAIMS AGAINST YOU FOR
DAMAGES (OTHER THAN THOSE UNDER THE FIRST ITEM LISTED
ABOVE); 2) LOSS OF, OR DAMAGE TO, YOUR RECORDS OR DATA; OR
3) SPECIAL, INCIDENTAL, OR INDIRECT DAMAGES OR FOR ANY
ECONOMIC CONSEQUENTIAL DAMAGES, LOST PROFITS OR LOST
SAVINGS, EVEN IF IBM, ITS SUPPLIERS OR YOUR RESELLER IS
INFORMED OF THEIR POSSIBILITY. SOME JURISDICTIONS DO NOT
ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR
CONSEQUENTIAL DAMAGES, SO THE ABOVE LIMITATION OR
EXCLUSION MAY NOT APPLY TO YOU.
Governing Law
Both you and IBM consent to the application of the laws of the country in
which you acquired the Machine to govern, interpret, and enforce all of your
and IBM’s rights, duties, and obligations arising from, or relating in any
manner to, the subject matter of this Agreement, without regard to conflict of
law principles.

Industry Canada requirements
Notice
The Industry Canada label identifies certified equipment. This certification
means that the equipment meets certain telecommunications networks
protective, operational, and safety requirements. The Department does not
guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to
be connected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of
communication. In some cases, the company’s inside wiring associated with a
single line individual service may be extended by means of a certified
connector assembly (telephone extension cord). The customer should be aware
that compliance with the above conditions may not prevent degradation of
service in some situations.
Repairs to certified equipment should be made by an authorized Canadian
maintenance facility designated by the supplier. Any repairs of alterations
made by the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the
equipment.
Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone lines and internal metallic water
pipe system, if present, are connected together. This precaution may be
particularly important in rural areas.
Caution
Users should not attempt to make such connections themselves, but should
contact the appropriate electric inspection authority, or electrician, as
appropriate.
The Ringer Equivalent Number (REN:0.3) assigned to each terminal device
provides an indication of the maximum number of terminals allowed to be
connected to a telephone interface. The termination on an interface may
consist of any combination of devices subject only to the requirement that the
sum of the Ringer Equivalence Number of all the devices does not exceed 5.

cause de mauvais fonctionnement.
Pour sa propre protection, l’utilisateur doit s’assurer que tous les fils de mise
à la terre de la source d’énergie électrique, des lignes téléphoniques et des
canalisations d’eau métalliques, s’il y en a, sont raccordés ensemble. Cette
précaution est particulièrement importante dans les régions rurales.
Avertissement
L’utilisateur ne doit pas tenter de faire ces raccordements lui-même; il doit
avoir recours à un service d’inspection des installations électriques, ou à
électricien, selon le cas.
L’indice de charge (IC) assigné à chaque dispositif terminal indique (REN:0.3),
