Caring for your ThinkPad computerThough your computer is designed to function reliably in normal workenvironments, you need to use common sense in handling it. By followingthese important tips, you will get the most use and enjoyment out of yourcomputer.Important tips:Be careful about where and how you workvDo not leave the base of your computer in contact with your lap or anypart of your body for an extended period when the computer is functioningor when the battery is charging. Your computer dissipates some heat duringnormal operation. This heat is a function of the level of system activity andbattery charge level. Extended contact with your body, even throughclothing, could cause discomfort or, eventually, a skin burn.vPlace liquids away from your computer to avoid spills, and keep yourcomputer away from water (to avoid the danger of electrical shock).vStore packing materials safely out of the reach of children to prevent therisk of suffocation from plastic bags.vKeep your computer away from magnets, activated cellular phones,electrical appliances, or speakers (within 13cm/5 in).vAvoid subjecting your computer to extreme temperatures (below 5°C/41°For above 35°C/95°F).Be gentle with your computervAvoid placing any objects (including paper) between the display and thekeyboard or under the keyboard.vDo not drop, bump, scratch, twist, hit, vibrate, push or place heavy objectson your computer, display, or external devices.vYour computer display is designed to be opened and used at an angleslightly greater than 90 degrees. Do not open the display beyond 180degrees, as this might damage the computer hinge.Carry your computer properlyvBefore moving your computer, be sure to remove any media, turn offattached devices, and disconnect cords and cables.vBe 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 dataloss.vWhen picking up your open computer, hold it by the bottom. Do not pickup or hold your computer by the display.Caring for your ThinkPad computer6ThinkPad®T23 Special Business Use
vUse 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 properlyvAvoid inserting diskettes at an angle and attaching multiple or loosediskette labels, as these can lodge in the drive.vIf your computer comes with a CD, DVD, or CD-RW/DVD drive, do nottouch the surface of a CD or the lens on the CD or DVD tray.vWait until you hear the CD or DVD click into the center pivot of the CD,DVD, or CD-RW/DVD drive before closing the CD or DVD tray.vWhen installing your hard disk, diskette, CD, DVD, or CD-RW/DVD drive,follow the instructions shipped with your hardware, and apply pressureonly where needed on the device. See Access ThinkPad, your on-board helpsystem, for information on replacing your hard disk drive (open AccessThinkPad by pressing the ThinkPad button.).Take care in setting passwordsvRemember your passwords. If you forget a supervisor or hard diskpassword, IBM will not reset it, and you might have to replace your systemboard or hard disk drive.Other important tipsvYour computer modem might use only an analog telephone network, orpublic-switched telephone network (PSTN). Do not connect the modem to aPBX (private branch exchange) or any other digital telephone extension linebecause this could damage your modem. Analog phone lines are often usedin homes, while digital phone lines are often used in hotels or officebuildings. If you are not sure which kind of phone line you are using,contact your telephone company.vYour computer might have both an Ethernet connector and a modemconnector. If so, be sure to connect your communication cable to the correctone, so your connector is not damaged. See Access ThinkPad, youron-board help system, for information on the location of these connectors(press the ThinkPad button to open Access ThinkPad).vRegister your ThinkPad products with IBM (refer to the Web page:www.ibm.com/pc/register). This can help authorities return your computerto you if it is lost or stolen. Registering your computer also enables IBM tonotify you about possible technical information and upgrades.vOnly an authorized IBM ThinkPad repair technician should disassembleand repair your computer.vDo not modify or tape the latches to keep the display open or closed.vTake care not to turn your computer over while the ac adapter is pluggedin. This could break the adapter plug.Caring for your ThinkPad computerChapter 1. Overview of your new ThinkPad computer 7
vTurn off your computer if you are replacing a device in a device bay, or elseverify that the device is warm-or hot-swappable.vIf you exchange drives in your computer, reinstall the plastic bezel faces (ifsupplied).vStore your external and removable hard disk, diskette, CD, DVD, andCD-RW/DVD drives in the appropriate containers or packaging when theyare not being used.Cleaning your computerOccasionally clean your computer as follows:vUse a soft cloth moistened with nonalkaline detergent to wipe the exteriorof the computer.vAvoid spraying cleaner directly on the display or the keyboard.vGently wipe the display with a soft, dry cloth. If you see a scratchlike markon your display, it might be a stain transferred from the keyboard or theTrackPoint pointer when the cover was pressed from the outside. Wipe ordust the stain gently with a soft, dry cloth. If the stain remains, moisten asoft, lint-free cloth with water that does not contain impurities, wring outas much of the water as you can, and then wipe the display again. Be sureto dry the display before closing it.Caring for your ThinkPad computer8ThinkPad®T23 Special Business Use
