You are requested to install and use your ThinkPad computer in strict accordance with the local RF regulations. Before you use the ThinkPad R51e Series computer, please find and read Regulatory Notice for ThinkPad R50 Series, the notice that supplements this Service and Troubleshooting Guide. The notice is included in the package with this publication. 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. For more information about recovering your hard disk to the original preinstalled contents, see "Recovering pre-installed software" on page 29, or refer to your on-board help source, Access Help. To open Access Help, press the Access IBM button, then select Access Help from the menu. © Copyright Lenovo 2005. © Portions Copyright IBM Corp. 2005. xvii xviii ThinkPad® R51e Series Service and Troubleshooting Guide Finding information with the Access IBM button The blue Access IBM button can help you in many situations when your computer is working normally, and even when it is not. At your desktop, press the Access IBM button to open ThinkVantageTM Productivity Center. ThinkVantage Productivity Center is your on-board computer help center that brings you informative illustrations and easy-to-follow instructions for getting started and staying productive. You can also use the Access IBM button to interrupt the startup sequence of your computer and start the ThinkVantage Rescue and RecoveryTM workspace. Use the Rescue and Recovery workspace to do the following: v Get essential system information. v Troubleshoot problems using diagnostics. v Restore your backups, assuming you have made backups using the Rescue and Recovery program. v Start the BIOS Setup Utility where you can view and change BIOS settings. v Start a utility that enables you to change your startup sequence. Some of the topics in your help system contain brief video clips that show you how to perform certain tasks, such as replacing your battery, inserting a PC Card, or upgrading your memory. Use the controls shown to play, pause, and rewind the video clip. © Copyright Lenovo 2005. © Portions Copyright IBM Corp. 2005. xix Note: If a bootable device is attached to the computer, and the boot priority of that device is higher than IDE HDD, the computer boots from that device. xx ThinkPad® R51e Series Service and Troubleshooting Guide Chapter 1.

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 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. Chapter 1. Overview of your new ThinkPad computer 5 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 Access Help, your on-board help system, for information on replacing your hard disk drive. 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. 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. 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 Help, your on-board help system, for information on the location of these connectors. v Register your ThinkPad products with Lenovo (refer to the Web page: www.lenovo.com/register). This can help authorities return your computer to you if it is lost or stolen. Registering your computer also enables Lenovo to notify you about possible technical information and upgrades. v Only an authorized ThinkPad repair technician should disassemble and repair your 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. 6 ThinkPad® R51e Series Service and Troubleshooting Guide Caring for your ThinkPad computer 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, DVD, and CD-RW/DVD drives in the appropriate containers or packaging when they are not being used. v Before you install any of the following devices, touch a metal table or a grounded metal object. This action reduces any static electricity from your body. The static electricity could damage the device. ­ ­ ­ ­ ­ ­ PC Card Smart Card Memory Card, such as SD Card, Memory Stick, and MultiMediaCard Memory module Mini-PCI Card Communication Daughter Card Cleaning the cover of your computer Occasionally clean your computer as follows: 1. Prepare a mixture of a gentle kitchen-use detergent (one that does not contain abrasive powder or strong chemicals such as acid or alkaline). Use 5 parts water to 1 part detergent. 2. Absorb the diluted detergent into a sponge. 3. Squeeze excess liquid from the sponge. 4. Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip. 5. Wipe the surface to remove the detergent. 6. Rinse the sponge with clean running water. 7. Wipe the cover with the clean sponge. 8. Wipe the surface again with a dry, soft lint-free cloth. 9. Wait for the surface to dry completely and remove any cloth fibers from the computer surface. Cleaning your computer keyboard 1. Absorb some isopropyl rubbing alcohol on a soft, dust-free cloth. 2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time, the cloth may hook onto an adjacent key and possibly damage it. Make sure that no liquid drips onto or between the keys. 3. Allow to dry. Chapter 1. Overview of your new ThinkPad computer 7 Caring for your ThinkPad computer 4. To remove any crumbs and dust from beneath the keys, you can use a camera blower with a brush or cool air from a hair drier. Note: Avoid spraying cleaner directly on the display or the keyboard. Cleaning your computer display 1. Gently wipe the display with a dry, soft lint-free cloth. If you see a scratchlike mark on your display, it might be a stain transferred from the keyboard or the TrackPoint pointing stick when the cover was pressed from the outside. 2. Wipe or dust the stain gently with a soft, dry cloth. 3. If the stain remains, moisten a soft, lint-free cloth with water or a 50-50 mixture of isopropyl alcohol and water that does not contain impurities. 4. Wring out as much of the liquid as you can. 5. Wipe the display again; do not let any liquid drip into the computer. 6. Be sure to dry the display before closing it. 8 ThinkPad® R51e Series Service and Troubleshooting Guide Chapter 2.
