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 Al ...
