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.

Do not drop, bump, scratch, twist, hit, vibrate, push or place heavy objects on your computer, display, or external devices.

ThinkPad®T61 Service and Troubleshooting Guide

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.

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).

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

ThinkPad®T61 Service and Troubleshooting Guide

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.

v 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.

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.

v If you exchange drives in your computer, reinstall the plastic bezel faces (if

supplied).

Taking care of your ThinkPad computer

Chapter 2. Taking care of your ThinkPad computer 5

v Store your external and removable hard disk, diskette or optical 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 – ExpressCard – Smart Card – Memory Card, such as xD-Picture Card, SD Card, Memory Stick, and

MultiMediaCard – Memory module – PCI Express 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.

Taking care of your ThinkPad computer

ThinkPad®T61 Service and Troubleshooting Guide

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

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.

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.
