Z61 Series 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

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).

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.

your computer properly

Carry

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.

Caring for your ThinkPad 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 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 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.

care in setting passwords

Take

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.

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 (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 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.

Z61 Series Service and Troubleshooting Guide

Caring for your ThinkPad computer

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).

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.

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

When 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.

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.

Chapter 2. Caring for your ThinkPad computer 5

Caring for your ThinkPad computer

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.

for the fingerprint reader

Care

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.

you notice any of the following conditions, gently clean the surface of the

If reader with a dry, soft, lint-free cloth:
