Overview of your new ThinkPad computer 5 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 5C/41F or above 35C/95F). 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. 6 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. 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 v 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. If you are an administrator, remember that setting a supervisor password can prevent unauthorized initialization. v 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 7 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 v verify that the device is warm- or hot-swappable. 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. 8 ThinkPad T23 Service and Troubleshooting Guide Chapter 2. Solving computer problems

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 inform IBM or your reseller of changes in a Machines location. d. Appendix B. Product warranties and notices 49 IBM is responsible for loss of, or damage to, your Machine while it is 1) in IBMs 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 IBMs 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 2. and tangible personal property; and 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 IBMs 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 IBMs 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. 50 ThinkPad T23 Service and Troubleshooting Guide Part 2 - Country-unique Terms AMERICAS BRAZIL Governing Law: The following is added after the first sentence:
