Avoid leaving the base of your computer, or any other part that becomes hot during operation, in contact with your lap or any part of your body for an extended period when the computer is turned on or when the battery is charging.

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 any communication lines, so that they cannot be pinched by your machine or other objects, walked on, tripped over, or in any way be subjected to treatment that could disturb the operation of your computer. Applying strong force to the cables may damage or break them.

To prevent damage to the hard disk and subsequent data loss, before moving your computer, press Fn+F4 to put it in standby mode or turn it off. Make sure that the standby status indicator is on (is green) before moving the computer.

2 ThinkPad® Z61 Service and Troubleshooting Guide

Chapter 2. Caring for 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

vDo not leave the base of your computer, or any other part that becomes hot during operation, 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.

vWhen 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.

vRoute the cables of an ac adapter, a mouse, a keyboard, a printer, or any other electronic device, or any communication lines, so that they cannot be pinched by your machine or other objects, walked on, tripped over, or in any way be subjected to treatment that could disturb the operation of your computer. Applying strong force to the cables may damage or break them.

vPlace liquids away from your computer to avoid spills, and keep your computer away from water (to avoid the danger of electrical shock).

vStore packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags.

vKeep your computer away from magnets, activated cellular phones, electrical appliances, or speakers (within 13 cm/5 in).

vAvoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F).

Be gentle with your computer

vAvoid placing any objects (including paper) between the display and the keyboard or under the keyboard.

Caring for your ThinkPad computer

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

vYour 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

vBefore moving your computer, be sure to remove any media, turn off attached 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 data loss.

vWhen picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by the display.

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 properly

vAvoid inserting diskettes at an angle and attaching multiple or loose diskette labels, as these can lodge in the drive.

vIf your computer comes with an optical drive, do not touch the surface of a disc or the lens on the tray.

vWait until you hear the CD or DVD click into the center pivot of an optical drive before closing the tray.

vWhen 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

vRemember 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

vYour 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.

4 ThinkPad® Z61 Service and Troubleshooting Guide

Caring for your ThinkPad computer

vYour 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.

vRegister 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.

vOnly an authorized ThinkPad repair technician should disassemble and 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 plugged in. This could break the adapter plug.

vTurn off your computer if you are replacing a device in a device bay, or else verify that the device is warmor hot-swappable.

vIf you exchange drives in your computer, reinstall the plastic bezel faces (if supplied).

vStore your external and removable hard disk, diskette or optical drives in the appropriate containers or packaging when they are not being used.

vBefore 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 Expess Mini Card

–Communication Daughter Card

vWhen transferring data to or from a Flash Media Card, such as an SD card, do not put your computer in 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.

Chapter 2. Caring for your ThinkPad computer 5

Caring for your ThinkPad computer

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 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:

vScratching the surface of the reader with a hard, pointed object.

vScraping the surface of the reader with your nail or anything hard.

vUsing or touching the reader with a dirty finger.

6 ThinkPad® Z61 Service and Troubleshooting Guide

Caring for your ThinkPad computer

If you notice any of the following conditions, gently clean the surface of the reader with a dry, soft, lint-free cloth:

vThe surface of the reader is dirty or stained.

vThe surface of the reader is wet.

vThe reader often fails to enroll or authenticate your fingerprint.
