This information can help you safely use your ThinkPad computer. Follow and retain all information included with your ThinkPad computer. The information in this document does not alter the terms of your purchase agreement or the Lenovo Statement of Limited Warranty. Customer safety is important to Lenovo. Our products are developed to be safe and effective. However, personal computers are electronic devices. Power cords, power adapters, and other features can create potential safety risks that can result in physical injury or property damage, especially if misused. To reduce these risks, follow the instructions included with your product, observe all warnings on the product and in the operating instructions, and review the information included in this document carefully. By carefully following the information contained in this document and provided with your product, you can help protect yourself from hazards and create a safer computer work environment. Note: This information includes references to power adapters and batteries. In addition to mobile personal computers, Lenovo ships some products (such as speakers or monitors) with external power adapters. If you have such a product, this information applies to your product. In addition, your computer product may contain a coin-sized internal battery that provides power to your system clock even when the machine is unplugged, so the battery safety information applies to all computers. Conditions that require immediate action Products can become damaged due to misuse or neglect. Some product damage is serious enough that the product should not be used again until it has been inspected and, if necessary, repaired by an authorized servicer. As with any electronic device, pay close attention to the product when it is turned on. On very rare occasions, you might notice an odor or see a puff of smoke or sparks vent from your machine. Or you might hear sounds like popping, cracking or hissing. These conditions might merely mean that an internal electronic component has failed in a safe and controlled manner. © Lenovo 2005. Portions © IBM Corp. 2005. v Or, they might indicate a potential safety issue. However, do not take risks or attempt to diagnose the situation yourself. Frequently inspect your computer and its components for damage or wear or signs of danger. If you have any question about the condition of a component, do not use the product. Contact the Customer Support Center or the product manufacturer for instructions on how to inspect the product and have it repaired, if necessary. For a list of Service and Support phone numbers, see "Worldwide telephone list" on page 67. In the unlikely event that you notice any of the conditions listed below, or if you have any safety concerns with your product, stop using the product and unplug it from the power source and telecommunication lines until you can speak to the Customer Support Center for further guidance. v Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are cracked, broken or damaged. v Signs of overheating, smoke, sparks or fire. v Damage to a battery (such as cracks, dents, creases), discharge from a battery, or a buildup of foreign substances on the battery. v A cracking, hissing or popping sound, or strong odor that comes from the product. v Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord or power adapter. v The computer product, the power cord or power adapter has been exposed to water. v The product has been dropped or damaged in any way. v The product does not operate normally when you follow the operating instructions. Note: If you notice these conditions with a product (such as an extension cord) that is not manufactured for or by Lenovo, stop using that product until you can contact the product manufacturer for further instructions, or until you get a suitable replacement. General safety guidelines Always observe the following precautions to reduce the risk of injury and property damage. Service Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center. Use only a service provider who is approved to repair your particular product. vi ThinkPad®X41 Tablet Service and Troubleshooting Guide Note: Some parts can be upgraded or replaced by the customer. These parts are referred to as Customer Replaceable Units, or CRUs. Lenovo expressly identifies CRUs as such, and provides documentation with instructions when it is appropriate for customers to replace those parts. You must closely follow all instructions when performing such replacements. Always make sure that the power is turned off and that the product is unplugged from any power source before you attempt the replacement. If you have any questions or concerns, contact the Customer Support Center. Although there are no moving parts in your computer after the power cord has been disconnected, the following warnings are required for proper UL certification. Danger Hazardous moving parts. Keep fingers and other body parts away. Attention: Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer cool before opening the cover. Power cords and power adapters Use only the power cords and power adapters supplied by the product manufacturer. The power cord and power adapter are intended for use with this product only. They should never be used with any other product. Never wrap a power cord around the power adapter or other object. Doing so can stress the cord in ways that can cause the cord to fray, crack or crimp. This can present a safety hazard. Always route power cords so that they will not be walked on, tripped over, or pinched by objects. Protect the cord and power adapters from liquids. For instance, do not leave your cord or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the cord or power adapter has been stressed by misuse. Liquids can also cause gradual corrosion of the power cord terminals and/or the connector terminals on the adapter which can eventually result in overheating. Important safety information vii Always connect power cords and signal cables in the correct order and ensure that all power cord connectors are securely and completely plugged into receptacles. Do not use any power adapter that shows corrosion at the ac input pins and/or shows signs of overheating (such as deformed plastic) at the ac input or anywhere on the power adapter. Do not use any power cords where the electrical contacts on either end show signs of corrosion or overheating or where the power cord appears to have been damaged in any way. Extension cords and related devices Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use are rated to handle the electrical requirements of the product. Never overload these devices. If power strips are used, the load should not exceed the power strip input rating. Consult an electrician for more information if you have questions about power loads, power requirements, and input ratings. Plugs and outlets If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged or corroded, do not use the outlet until it is replaced by a qualified electrician. Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement. Some products are equipped with a three-pronged plug. This plug fits only into a grounded electrical outlet. This is a safety feature. Do not defeat this safety feature by trying to insert it into a non-grounded outlet. If you cannot insert the plug into the outlet, contact an electrician for an approved outlet adapter or to replace the outlet with one that enables this safety feature. Never overload an electrical outlet. The overall system load should not exceed 80 percent of the branch circuit rating. Consult an electrician for more information if you have questions about power loads and branch circuit ratings. Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the equipment. Do not fully extend power cords in a way that will stress the cords. Carefully connect and disconnect the equipment from the electrical outlet. Batteries All personal computers manufactured by Lenovo contain a non-rechargeable coin cell battery to provide power to the system clock. In addition many viii ThinkPad®X41 Tablet Service and Troubleshooting Guide mobile products such as ThinkPad notebook PCs utilize a rechargeable battery pack to provide system power when in portable mode. Batteries supplied by Lenovo for use with your product have been tested for compatibility and should only be replaced with approved parts. Never attempt to open or service any battery. Do not crush, puncture, or incinerate batteries or short circuit the metal contacts. Do not expose the battery to water or other liquids. Only recharge the battery pack strictly according to instructions included in the product documentation. Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame to "vent" from the battery pack or coin cell. If your battery is damaged, or if you notice any discharge from your battery or the buildup of foreign materials on the battery leads, stop using the battery and obtain a replacement from the battery manufacturer. Batteries can degrade when they are left unused for long periods of time. For some rechargeable batteries (particularly Lithium Ion batteries), leaving a battery unused in a discharged state could increase the risk of a battery short circuit, which could shorten the life of the battery and can also pose a safety hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or store these batteries in a discharged state. Heat and product ventilation Computers generate heat when turned on and when batteries are charging. Notebook PCs can generate a significant amount of heat due to their compact size. Always follow these basic precautions: 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 produces some heat during normal operation. Extended contact with the body could cause discomfort or, potentially, a skin burn. v Do not operate your computer or charge the battery near flammable materials or in explosive environments. v Ventilation slots, fans and/or heat sinks are provided with the product for safety, comfort, and reliable operation. These features might inadvertently become blocked by placing the product on a bed, sofa, carpet, or other flexible surface. Never block, cover or disable these features. You should inspect your desktop computer for dust accumulation at least once every three months. Before inspecting your computer, turn off the power and unplug the computer's power cord from the electrical outlet; then remove any dust from vents and perforations in the bezel. If you notice external dust accumulation, you should also examine and remove dust from the inside of the computer including heat sink inlet fins, power supply vents, and fans. Important safety information ix Always turn off and unplug the computer before opening the cover. If possible, avoid operating your computer within 2 feet of high-traffic areas. If you must operate your computer in or near a high-traffic area, you should inspect and, if necessary, clean your computer more frequently. For your safety and to maintain optimum computer performance, always follow these basic precautions with your desktop computer: v Keep the cover closed whenever the computer is plugged in. v Regularly inspect the outside of the computer for dust accumulation. v Remove dust from vents and any perforations in the bezel. More frequent cleanings might be required for computers in dusty or high-traffic areas. v Do not block or restrict airflow into the front of the computer. v Do not block the airflow vents on the back of the computer. v Do not store or operate your computer inside furniture, as this might increase the risk of overheating. v Airflow temperatures into the computer should not exceed 35° C (95° F). v Do not use non-ThinkCentre air filtration devices. CD and DVD drive safety CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or otherwise physically damaged, it is possible for the disc to break apart or even shatter when the CD drive is in use. To protect against possible injury due to this situation, and to reduce the risk of damage to your machine, do the following: v Always store CD/DVD discs in their original packaging v Always store CD/DVD discs out of direct sunlight and away from direct heat sources v Remove CD/DVD discs from the computer when not in use v Do not bend or flex CD/DVD discs, or force them into the computer or their packaging v Check CD/DVD discs for cracks before each use.

Information about hard disk capacity Instead of providing a recovery CD or a Windows® CD with your computer, Lenovo provides simpler methods of accomplishing the tasks typically associated with these CDs. The files and programs for these alternative methods are on your hard disk, which eliminates having to locate misplaced CDs and problems associated with using an incorrect CD version. The complete backup of all the files and programs that Lenovo preinstalled on your computer resides in a hidden section, or partition, of the hard disk. Although hidden, the backups in the partition consume hard disk space. Therefore, when checking the capacity of your hard disk according to Windows, you might note that the total capacity of the disk appears to be smaller than anticipated. This discrepancy is explained by the contents of the hidden partition. (See "Recovering pre-installed software" on page 31.) For more information about recovering your hard disk to the original preinstalled contents, refer to your on-system help source. Press the blue Access IBM button or click the Access IBM icon on your desktop, and then browse the Learn section for various topics that cover backing up and recovering. © Lenovo 2005.

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 13 cm/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 180 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®X41 Tablet 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 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 an optical drive such as CD, DVD, or CD-RW/DVD drive, do not touch the surface of a disc or the lens on the tray. v Wait until you hear the CD or DVD click into the center pivot of an optical drive such as CD, DVD, or CD-RW/DVD drive before closing the tray. v When installing your hard disk, diskette, CD, DVD, or CD-RW/DVD drive, follow the instructions shipped with your hardware, and apply pressure only where needed on the device. See your on-board help system for information on replacing your hard disk drive (open ThinkVantage Productivity Center by pressing the Access IBM button). Take care in setting passwords v Remember your passwords. If you forget a supervisor or hard disk password, Lenovo will not reset it, and you might have to replace your system board or hard disk drive. Tips on using your computer in tablet mode v If you close the computer display, make sure that the display is rotated either at 0 degrees, so that if faces the keyboard, or at 180 degrees, so that the back of the display faces the keyboard. v Do not pick up or hold the computer by the display only. v Do not hit, vibrate, or bump the computer display. v To allow free ventilation, do not place any obstacle, such as a thick-piled carpet or a soft cushion, in front of the fan. v When you use the computer in picture frame mode, in which the display is rotated until the back of the display is facing the keyboard, hold the display with one hand and use the Tablet Digitizer Pen. v If you hold the computer in one hand while using it in tablet mode, do not expose it to excessive vibration, shock, or rotation. v Do not use the computer outdoors. Do not expose it to rain. v If you put your computer in a carrying case, put it into notebook mode and close the display. Tips on using the Tablet Digitizer Pen v Use only the Tablet Digitizer Pen that was shipped with your ThinkPad X41 Tablet computer or that you purchased with that computer as an option. Chapter 1. Overview of your new ThinkPad computer 7 Caring for your ThinkPad computer Only this pen is designed for use with the ThinkPad X41 Tablet computer. Any other pen might stick in the penholder or cause other problems. v The Tablet Digitizer Pen is not waterproof. Take care not to soak or dip the pen in water. Other important tips v Your computer modem might 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.
