DANGER

vTo 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.

vDo 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.

vTo reduce the risk of electric shock, do not use your computer in or near water.

vTo 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.

vStore packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags.

vThe 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.

vTo reduce the risk of fire, use only No. 26 AWG or thicker telephone cable.

vThe 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.

vDo not open the CD-ROM or DVD drive unit, as this might result in hazardous radiation exposure.

vAvoid direct eye exposure with the laser beam contained in some drives.

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.

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

Wireless Interoperability

IBM ThinkPad 802.11b Wireless LAN Mini-PCI Adapter (P/N 26P8056)

(hereafter called Wireless LAN Mini-PCI Adapter) is designed to be

interoperable with any wireless LAN product that is based on Direct Sequence

Spread Spectrum (DSSS) radio technology, and is compliant to:

66 ThinkPad

T23 Service and Troubleshooting Guide

vThe IEEE 802.11 Standard on Wireless LANs (Revision B), as defined and

approved by the Institute of Electrical and Electronics Engineers.

vThe Wireless Fidelity (WiFi) certification as defined by the WECA (Wireless

Ethernet Compatibility Alliance).

Usage environment and your Health

Wireless LAN Mini-PCI Adapter emits radio frequency electromagnetic energy

like other radio devices. However, the level of energy emitted is far much less

than the electromagnetic energy emitted by wireless devices like for example

mobile phones.

Because Wireless LAN Mini-PCI Adapter operates within the guidelines found

in radio frequency safety standards and recommendations, IBM believes it is

safe for use by consumers. These standards and recommendations reflect the

consensus of the scientific community and result from deliberations of panels

and committees of scientists who continually review and interpret the

extensive research literature. In some situation or environment, the use of

Wireless LAN Mini-PCI Adapter may be restricted by the proprietor of the

building or responsible representatives of the organization. These situations

may for example include:

vUsing Wireless LAN Mini-PCI Adapter on board of airplanes, or

vIn any other environment where the risk of interference to other devices or

services is perceived or identified as harmful.

If you are uncertain of the policy that applies on the use of wireless devices in

a specific organization (e.g. airport), you are encouraged to ask for

authorization to use Wireless LAN Mini-PCI Adapter prior to turning on the

ThinkPad T23.

Wireless Regulatory Information

The ThinkPad T23 must be installed and used in strict accordance with the

instructions as described hereafter. This product complies with the following

radio frequency and safety standards.

USA - Federal Communications Commission (FCC)

This product complies with FCC Part 15. The operation of Wireless LAN

Mini-PCI Adapter integrated in the product is subject to the following two

conditions:

vIt may not cause harmful interference.

vIt accepts any interference that may cause undesired operation.

Exposure to Radio Frequency Radiation

The radiated output power of Wireless LAN Mini-PCI Adapter is far below

the FCC radio frequency exposure limits. Nevertheless, the ThinkPad T23

shall be used in such a manner that the potential for human contact during

normal operation is minimized as follows:

Appendix B. Product warranties and notices 67
