Caring for your 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 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. © Copyright Lenovo 2005 3 Caring for your computer v When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by the display. 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 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. Take care in setting passwords v Remember your passwords. If you forget a supervisor or hard disk password, Lenovo authorized service provider 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. v Register your Lenovo 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 Lenovo notebook 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. 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. 4 Lenovo 3000 C100 Service and Troubleshooting Guide Caring for your computer 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 MultiMedia Card ­ Memory module 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. 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 when the cover was pressed from the outside. Chapter 2. Caring for your computer 5 Caring for your computer 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. 6 Lenovo 3000 C100 Service and Troubleshooting Guide Chapter 3.

Recovery options Introducing Rescue and Recovery If v v v Windows is not running properly, you may need to do the following: Get the current system information. Diagnose and troubleshoot a problem. Rescue a file from your Windows environment or restore backed-up files, provided you have made backups by use of the ThinkVantage Rescue and Recovery program. v Configure your computer. All this can be achieved from the ThinkVantage Rescue and Recovery workspace. To start ThinkVantage Rescue and Recovery, turn on the computer and while the initial screen is displayed press the Lenovo Care button. For more information about using Rescue and Recovery features, see the "Recovery overview" section of the Access Help. Restoring factory contents 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 protected area, 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. The Product Recovery Program contained within this area enables you to restore the complete contents of your hard disk to the same state as it was when originally shipped from the factory. To recover the hard disk to its original contents, do the following: Note: When you recover your system, you need to select the On position of the wireless radio switch on the computer. If you forget to select the On © Copyright Lenovo 2005 23 Recovering pre-installed software position of the wireless radio switch, your wireless network card will not be recognized, and the wireless card driver will not be included in your system. Note: The recovery process might take up to 2 hours. Attention: All of the files on the primary hard disk partition (usually drive C) will be lost in the recovery process. However, before any data is overwritten, you will be given the opportunity to save one or more files to other media. 1. If possible, save all your files and shut down your operating system. 2. Turn off your computer for at least 5 seconds. 3. Turn on your computer. Watch the display carefully while your PC starts. While the initial screen is displayed, press the Lenovo Care button. The ThinkVantage Rescue and Recovery workspace opens. 4. Click Restore your system, select Restore my hard drive to the original factory state, and follow the instructions on the screen. Recovering data If you performed a backup operation using the Rescue and Recovery program, you also have one or more backups stored that reflect the contents of the hard disk as it existed at various points in time. These backups might be stored on your hard disk, or a network drive, or on removable media, depending on the options you selected during the backup operation. You can use either the Rescue and Recovery program or the ThinkVantage Rescue and Recovery workspace to restore the contents of the hard disk to an earlier state using any of the stored backups. The ThinkVantage Rescue and Recovery workspace runs independently of the Windows operating system. Therefore, you can start it by pressing the Lenovo Care button when prompted during startup. After the ThinkVantage Rescue and Recovery workspace opens you can perform a recovery operation, even if you are unable to start Windows. 24 Lenovo 3000 C100 Service and Troubleshooting Guide Chapter 5.

Touch a metal table or a grounded metal object. This action reduces any static electricity in your body, that could damage the SO-DIMM. Do not touch the contact edge of the SO-DIMM. 2. Turn off the computer; then disconnect the ac adapter and all cables from the computer. 3. Close the computer display, and turn the computer over. 4. Remove the battery. 5. Loosen the two screws on the memory slot cover, and remove them. 6. If two SO-DIMMs are already installed in the memory slots, remove one of them to make room for the new one by pressing out on the latches on both edges of the socket at the same time. Be sure to save it for future use. 7. With the notched end of the SO-DIMM toward the contact edge side of the socket, firmly insert the SO-DIMM into the socket at an angle of about 20 degrees; then pivot it downward until it snaps into place. Chapter 5. Upgrading and replacing devices 29 Replacing memory 8. Reinstall the memory slot cover by aligning the front side of the cover first, and tighten the screws. 9. Reinstall the battery. 10.
