`
`When your computer is turned on or the battery is
`charging, the base, the palm rest, and some other
`parts may become hot. Avoid keeping your hands,
`your lap, or any other part of your body in contact
`with a hot section of the computer for any extended
`length of time. When you use the keyboard, avoid
`keeping your palms on the palm rest for a
`prolonged period of time.
`
`Your computer generates some heat during normal
`operation. The amount of heat depends on the
`amount of system activity and the battery charge
`level. Extended contact with your body, even
`through clothing, could cause discomfort or even a
`skin burn. Periodically take breaks from using the
`keyboard by lifting your hands from the palm rest;
`and be careful not to use the keyboard for any
`extended length of time.
`
`When the ac adapter is connected to an electrical
`outlet and your computer, it generates heat. Do not
`place the adapter in contact with any part of your
`body while using it. Never use the ac adapter to
`warm your body. Extended contact with your body,
`even through clothing, may cause a skin burn.

`Route the cables of an ac adapter, a mouse, a
`keyboard, a printer, or any other electronic device,
`or communication lines, so that they cannot be
`walked on, tripped over, pinched by your computer
`or other objects, or in any way subjected to
`treatment that could disturb the operation of your
`computer. Applying strong force to the cables may
`damage or break them.
`
`Before moving your computer, do one of the
`following: turn it off, press Fn+F4 to put it in sleep
`(standby) mode, or press Fn+F12 to put it in
`hibernation mode.
`
`Before moving the computer, make sure that the
`power on indicator is off. This will help to prevent
`damage to the hard disk drive, and possible loss of
`data.

`
`Chapter 2. Taking care of your ThinkPad 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 When your computer is turned on or the battery is charging, the base, the
`palm rest, and some other parts may become hot. Avoid keeping your
`hands, your lap, or any other part of your body in contact with a hot
`section of the computer for any extended length of time. When you use the
`keyboard, avoid keeping your palms on the palm rest for a prolonged
`period of time.
`Your computer generates some heat during normal operation. The amount
`of heat depends on the amount of system activity and the battery charge
`level. Extended contact with your body, even through clothing, could cause
`discomfort or even a skin burn. Periodically take breaks from using the
`keyboard by lifting your hands from the palm rest; and be careful not to
`use the keyboard for any extended length of time.
`v When the ac adapter is connected to an electrical outlet and your computer,
`it generates heat. Do not place the adapter in contact with any part of your
`body while using it. Never use the ac adapter to warm your body.
`Extended contact with your body, even through clothing, may cause a skin
`burn.
`v Route the cables of an ac adapter, a mouse, a keyboard, a printer, or any
`other electronic device, or communication lines, so that they cannot be
`walked on, tripped over, pinched by your machine or other objects, or in
`any way subjected to treatment that could disturb the operation of your
`computer. Applying strong force to the cables may damage or break them.
`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 or 5 in).
`v Avoid subjecting your computer to extreme temperatures (below 5°C/41°F
`or above 35°C/95°F).

`
`Taking care of your ThinkPad computer
`
`v Some appliances, such as certain portable desktop fans or air purifiers, can
`produce negative ions. If a computer is close to such an appliance, and is
`exposed for an extended time to air containing negative ions, it may
`become electrostatically charged. Such a charge may be discharged through
`your hands when you touch the keyboard or other parts of the computer,
`or through connectors on I/O devices connected to it. Even though this
`kind of electrostatic discharge (ESD) is the opposite of a discharge from
`your body or clothing to the computer, it poses the same risk of a computer
`malfunction.
`Your computer is designed and manufactured to minimize any effects of
`electrostatic charge. An electrostatic charge above a certain limit, however,
`can increase the risk of ESD. Therefore, when using the computer close to
`an appliance that can produce negative ions, give special attention to the
`following:
`– Avoid directly exposing your computer to the air from an appliance that
`can produce negative ions.
`– Keep your computer and peripherals as far as possible from such an
`appliance.
`– Wherever possible, ground your computer to facilitate safe electrostatic
`discharge.
`
`Note: Not all such appliances cause a significant electrostatic charge.
`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 sleep (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.
`v Use a quality carrying case that provides adequate cushion and protection.
`Do not pack your computer in a tightly packed suitcase or bag.

`
`Taking care of your ThinkPad computer
`
`v
`
`Handle storage media and drives properly
`v
`If your computer comes with a diskette drive, avoid inserting diskettes at
`an angle and attaching multiple or loose diskette labels, as these can lodge
`in the drive.
`If your computer comes with an optical 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 before closing the tray.
`v When installing your hard disk, diskette or optical 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.
`Tips on using your computer in tablet mode
`v To close the computer display, first make sure that the display either faces
`the keyboard or is positioned at 180 degrees to the keyboard, 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, hold the display with
`one hand and use the Tablet Digitizer Pen.
`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 X61
`Tablet computer or that you purchased with that computer as an option.
`Only this pen is designed for use with the ThinkPad X61 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.
`Tips on using the touch panel
`v The touch panel is a glass panel covered with a plastic film. For input you
`can use either your finger or the Tablet Digitizer Pen shipped with your
`
`v

`
`computer. Do not use any pen other than the specified one, or any metallic
`object, because to do so might damage the touch panel or cause it to
`malfunction.
`If you put your computer in a carrying case, put it into notebook mode and
`close the display. Do not carry your computer in tablet mode.
`If you use both your finger and the Tablet Digitizer Pen simultaneously for
`input to the screen, only data entered by use of the Digitizer Pen will be
`processed.
`If you use your finger to input to the touch panel, touch only one point at a
`time. If you touch several points simultaneously, the input will not be
`processed correctly.
`v With the touch panel, gradually a discrepancy may start to appear between
`the point you touched with your finger during the finger point, and its
`actual position on the screen. To avoid this, regularly correct the accuracy of
`the finger input by use of the touch panel Settings Utility.
`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 ThinkPad products with Lenovo (visit the following Web site:
`http://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.
`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.
`If you exchange drives in your computer, reinstall the plastic bezel faces (if
`supplied).
`v Store your external and removable hard disk, diskette or optical drives in
`the appropriate containers or packaging when they are not being used.

`
`Taking care of your ThinkPad 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 xD-Picture Card, SD Card, Memory Stick, and
`MultiMediaCard
`– Memory module
`– PCI Expess Mini Card
`– Communication Daughter Card
`v When transferring data to or from a Flash Media Card, such as an SD card,
`do not put your computer in sleep (standby) or hibernation mode before
`the data transfer is complete. To do so might cause damage to your data.
`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 dryer.
`
`Note: Avoid spraying cleaner directly on the display or the keyboard.

`
`Taking care of your ThinkPad computer
`
`Cleaning your computer display
`1. Gently wipe the display with a dry, soft lint-free cloth. If you see a
`scratch-like 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.
`Cleaning the touch panel display
`1. To remove fingerprints, etc., from the touch panel display, use a dry, soft,
`lint-free cloth. (A piece of absorbent cotton will also serve the purpose.)
`Do not apply solvents to the cloth.
`2. Gently wipe foreign particles and dust from the touch panel with one side
`of the cloth.
`3. Wipe smudges or fingerprints with the other side of the cloth, or with a
`clean cloth.
`4. After using the cloth, wash it with a neutral detergent.
`Care for the fingerprint reader
`The following actions could damage the fingerprint reader or cause it not to
`work properly:
`v Scratching the surface of the reader with a hard, pointed object.
`v Scraping the surface of the reader with your nail or anything hard.
`v Using or touching the reader with a dirty finger.
`
`If you notice any of the following conditions, gently clean the surface of the
`reader with a dry, soft, lint-free cloth:
`v The surface of the reader is dirty or stained.
`v The surface of the reader is wet.
`v The reader often fails to enroll or authenticate your fingerprint.
