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.
„Be careful about where and how you work
 Do not eat or smoke over your keyboard. Particles that fall into your keyboard can cause 
damage.
 Store packing materials safely out of the reach of children to prevent the risk of suffocation 
from plastic bags.
 Keep your computer away from magnets, activated cellular phones, electrical appliances, or 
speakers (within 13 cm or 5 in).
 Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/
95°F).
 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.
„Notice of static-electricity
When you handle options or CRUs, or perform any work inside the computer, take the 
following precautions to avoid static-electricity damage:
-  Limit your movement. Movement can cause static electricity to build up around you.
-  Always handle components carefully. Handle adapters, memory modules, and other circuit
boards by the edges. Never touch exposed circuitry.
-  Prevent others from touching components.
- When you install a static-sensitive option or CRU, touch the static-protective package
containing the part to a metal expansion-slot cover or other unpainted metal surface on the
computer for at least two seconds. This reduces static electricity in the package and your
body. 
						

							Appendix B. Use, and care information
37
-  Whenever possible, remove the static-sensitive part from the static-protective packaging
and install the part without setting it down. When this is not possible, place the static-
protective packaging on a smooth, level surface and place the part on it.
-  Do not place the part on the computer cover or other metal surface.
„Be gentle with your computer
 Avoid placing any objects (including paper) between the display and the keyboard or under 
the keyboard.
 Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on your computer, 
display, or external devices.
 Avoid turning the display beyond 130°.
„Carry your computer properly
 Before moving your computer, be sure to remove any media, turn off attached devices, and 
disconnect cords and cables.
 Be sure your computer is in sleep or hibernation mode, or turned off, before moving it. This 
will prevent damage to the hard disk drive and data loss.
 When picking up your open computer, hold it by the bottom. Do not pick up or hold your 
computer by the display.
 Use a quality carrying case that provides adequate cushion and protection. Do not pack your 
computer in a tightly packed suitcase or bag.
„For outdoor use
 Backup your critical data before you take your computer outdoors.
 Ensure that the battery is full.
 Be sure to turn off the power and close the LCD well.
 When you leave the computer in your car, place it on the back seat to avoid being insolated.
 Carry the AC adapter and power cord with the computer.
„Handle storage media and drives properly
 If your computer comes with an optical drive, do not touch the surface of a disc or the lens on 
the tray.
 Wait until you hear the CD or DVD click into the center pivot of an optical drive before 
closing the tray.
 When installing your hard disk, follow the instructions shipped with your hardware, and 
apply pressure only where needed on the device. 
						

							38
Appendix B. Use, and care information
„Data safety
 Do not delete unknown files or change the name of files or directories that were not created by 
you; otherwise, your computer software might fail to work.
 Be aware that accessing network resources can leave your computer vulnerable to computer 
viruses, hackers, spyware, and other malicious activities that might damage your computer, 
software, or data.
 It is your responsibility to ensure that you have adequate protection in the form of firewalls, 
antivirus software, and anti-spyware software and keep this software up to date.
„Take care in setting passwords
 Remember your passwords. If you forget a supervisor or hard disk password, Lenovo 
authorized service providers will not reset it, and you might have to replace your system 
board or hard disk drive.
„Other important tips
 Do not put the battery pack in trash that is disposed of in landfills. When disposing of the 
battery, comply with local ordinances or regulations and your company’s safety standards.
 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.
 Register your Lenovo products with Lenovo (refer to the Web page: 
http://consumersupport.lenovo.com
). 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.
 Only an authorized Lenovo repair technician should disassemble and repair your computer.
 Do not modify or tape the latches to keep the display open or closed.
 Take care not to turn your computer over while the AC adapter is plugged in. This could 
break the adapter plug.
 Turn off your computer if you are replacing a device, or else verify that the device is warm- or 
hot-swappable.
 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.
- ExpressCard
-  Memory Card, such as SD Card, Memory Stick, MultiMediaCard, xD-Picture Card, and
Memory Stick Pro card.
- Memory module
 When transferring data to or from a Flash Media Card, such as an SD card, do not put your 
computer in sleep or hibernation mode before the data transfer is complete. To do so might 
cause damage to your data.

„Ergonomic information 
Working in the virtual office may mean adapting to frequent changes in your environment. 
Following some simple rules will make things easier and bring you the maximum benefits of 
your computer. Keeping in mind such basics as good lighting and proper seating, for example, 
can help you improve your performance and achieve greater comfort.
„What if you are traveling? 
It may not be possible to observe the best ergonomic practices when you are using your 
computer while on the move or in a casual setting. Regardless of the setting, try to observe as 
many of the tips as possible. Sitting properly and using adequate lighting, for example, will help 
you maintain desirable levels of comfort and performance.
„Questions about vision? 
Your computer ’s visual display screen is designed to meet the highest standards and to provide 
you with clear, crisp images and large, bright displays that are easy to see, yet easy on the eyes. 
Of course, any concentrated and sustained visual activity can be tiring. If you have questions on 
eye fatigue or visual discomfort, consult a vision care specialist for advice.
Note:This example shows someone in a conventional setting. Even if you work in a casual, less 
conventional setting, many of the tips in this section still apply. Develop good habits, and they will 
serve you well.

An important part of owning your computer is maintenance. With proper care, you can avoid 
common problems. The following sections provide information that can help you to keep your 
computer running smoothly.
„General tips for maintenance 
1Check the capacity of your hard disk drive from time to time. If the hard disk drive gets too 
full, Windows® will slow down and might produce errors.
2Empty your recycle bin on a regular basis.
3Use the Microsoft Disk Defragmenter on your hard disk drive on a regular basis to improve 
data seek and read time. 
 To free up disk space, uninstall unused application programs.
 Clean out your Inbox, Sent, and Trash folders from your e-mail client program.
 At least once a week, make a point to back up your data. If critical data is present, it is a good 
idea to perform a daily backup. Lenovo has many backup options available for your 
computer. CD-RW drives and CD-RW/DVD drives are available for most computers and are 
easily installed.
 Use or schedule System Restore to take a system snapshot periodically.
 Update device drivers and BIOS when needed.
 Profile your machine at http://consumersupport.lenovo.com
 to keep up to date with current 
drivers and revisions.
 Keep up to date on device drivers on other non-Lenovo hardware. You might want to read the 
device driver information release notes prior to updating for compatibility or known issues.
 Keep a log book. Entries might include major hardware or software changes, driver updates, 
minor issues you have experienced and how you resolved them.
 If you ever need to run a recovery operation on your computer by OneKey Rescue system, see 
“Chapter 4. OneKey Rescue system” on page 19.
 If required, you can find your country’s customer support center at the following Web 
address: http://consumersupport.lenovo.com
. 
When calling the customer support center, please make sure you have your machine type, 
model, and serial number available and the computer is in front of you. Also, if the machine is 
producing error codes, it is helpful to have the error screen on or the message written down.
Note:Always take a system snapshot before installing new drivers, updating software, or installing new 
software.

41 „Cleaning the cover of your computer
Occasionally clean your computer as follows:
1Prepare 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.
2Absorb the diluted detergent into a sponge.
3Squeeze excess liquid from the sponge.
4Wipe the cover with the sponge, using a circular motion and taking care not to let any 
excess liquid drip.
5Wipe the surface to remove the detergent.
6Rinse the sponge with clean running water.
7Wipe the cover with the clean sponge.
8Wipe the surface again with a dry, soft lint-free cloth.
9Wait for the surface to dry completely and remove any cloth fibers from the computer 
surface.
„Cleaning your computer keyboard
1Absorb some isopropyl rubbing alcohol on a soft, dust-free cloth.
2Wipe 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.
3Allow to dry.
4To 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.
„Cleaning your computer display
1Gently 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 when the cover was pressed from 
the outside.
2Wipe or dust the stain gently with a soft, dry cloth.
3If 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.
4Wring out as much of the liquid as you can.
5Wipe the display again; do not let any liquid drip into the computer.
6Be sure to dry the display before closing it.
Note:Shut down the computer and then disconnect the power cord before cleaning the computer.
Note:Avoid spraying cleaner directly on the display or the keyboard.
