Important safety information  
CAUTION:  
Before using this manual, be sure to read and understand all the related safety information for this  
product. Refer to the information in this section and the safety information in the Safety, Warranty, and  
Setup Guide that you received with this product. Reading and understanding this safety information  
reduces the risk of personal injury and damage to your product.  
If you no longer have a copy of the Safety, Warranty, and Setup Guide, you can obtain a Portable Document  
Format (PDF) version from the Lenovo® Support Web site at http://www.lenovo.com/support. The Lenovo  
Support Web site also provides the Safety, Warranty, and Setup Guide and this User Guide in additional  
languages.  
Service and upgrades  
Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or  
your documentation. Only use a Service Provider who is approved to repair your particular product.  
Note: Some computer parts can be upgraded or replaced by the customer. Upgrades typically are  
referred to as options. Replacement parts approved for customer installation are referred to as Customer  
Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for  
customers to install options or replace CRUs. You must closely follow all instructions when installing or  
replacing parts. The Off state of a power indicator does not necessarily mean that voltage levels inside a  
product are zero. Before you remove the covers from a product equipped with a power cord, always make  
sure that the power is turned off and that the product is unplugged from any power source. For more  
information on CRUs, refer to Chapter 5 “Installing or replacing hardware” on page 37. If you have any  
questions or concerns, contact the Customer Support Center.  
Although there are no moving parts in your computer after the power cord has been disconnected, the  
following warnings are required for your safety.  
CAUTION:  
Hazardous moving parts. Keep fingers and other body parts away.  
CAUTION:  
Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer  
cool before opening the cover.  
Static electricity prevention  
Static electricity, although harmless to you, can seriously damage computer components and options.  
Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option

or CRU, do not open the static-protective package containing the part until the instructions direct you  
to install it.  
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.  
• When 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.  
Power cords and power adapters  
Use only the power cords and power adapters supplied by the product manufacturer.  
The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or better. For  
other countries, the suitable types shall be used accordingly.  
Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that  
can cause the cord to fray, crack, or crimp. This can present a safety hazard.  
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.  
Protect power cord and power adapters from liquids. For instance, do not leave your power cord or power  
adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a  
short circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also can  
cause gradual corrosion of power cord terminals and/or the connector terminals on a power adapter,  
which can eventually result in overheating.  
Always connect power cords and signal cables in the correct order and ensure that all power cord  
connectors are securely and completely plugged into receptacles.  
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (such  
as deformed plastic) at the ac input or anywhere on the power adapter.  
Do not use any power cords where the electrical contacts on either end show signs of corrosion or  
overheating or where the power cord appears to have been damaged in any way.  
Extension cords and related devices  
Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use  
are rated to handle the electrical requirements of the product. Never overload these devices. If power strips  
are used, the load should not exceed the power strip input rating. Consult an electrician for more information  
if you have questions about power loads, power requirements, and input ratings.

Plugs and outlets  
If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged  
or corroded, do not use the outlet until it is replaced by a qualified electrician.  
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement.  
Do not share an electrical outlet with other home or commercial appliances that draw large amounts of  
electricity; otherwise, unstable voltage might damage your computer, data, or attached devices.  
Some products are equipped with a three-pronged plug. This plug fits only into a grounded electrical outlet.  
This is a safety feature. Do not defeat this safety feature by trying to insert it into a non-grounded outlet. If  
you cannot insert the plug into the outlet, contact an electrician for an approved outlet adapter or to replace  
the outlet with one that enables this safety feature. Never overload an electrical outlet. The overall system  
load should not exceed 80 percent of the branch circuit rating. Consult an electrician for more information  
if you have questions about power loads and branch circuit ratings.  
Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the  
equipment. Do not fully extend power cords in a way that will stress the cords.  
Be sure that the power outlet provides the correct voltage and current for the product you are installing.  
Carefully connect and disconnect the equipment from the electrical outlet.  
External devices  
Do not connect or disconnect any external device cables other than Universal Serial Bus (USB) and 1394  
cables while the computer power is on; otherwise, you might damage your computer. To avoid possible  
damage to attached devices, wait at least five seconds after the computer is shut down to disconnect  
external devices.  
Heat and product ventilation  
Computers, power adapters, and many accessories can generate heat when turned on and when batteries  
are charging. Always follow these basic precautions:  
• Do not leave your computer, power adapter, or accessories in contact with your lap or any part of your  
body for an extended period when the products are functioning or when the battery is charging. Your  
computer, power adapter, and many accessories produce some heat during normal operation. Extended  
contact with the body could cause discomfort or, potentially, a skin burn.  
• Do not charge the battery or operate your computer, power adapter, or accessories near flammable  
materials or in explosive environments.  
• Ventilation slots, fans, and heat sinks are provided with the product for safety, comfort, and reliable  
operation. These features might inadvertently become blocked by placing the product on a bed, sofa,  
carpet, or other flexible surface. Never block, cover, or disable these features.  
Inspect your desktop computer for dust accumulation at least once every three months. Before inspecting  
your computer, turn off the power and unplug the computer's power cord from the electrical outlet; then  
remove any dust from vents and perforations in the bezel. If you notice external dust accumulation, then  
examine and remove dust from the inside of the computer including heat sink inlet fins, power supply vents,  
and fans. Always turn off and unplug the computer before opening the cover. If possible, avoid operating  
your computer within two feet of high-traffic areas. If you must operate your computer in or near a high-traffic  
area, inspect and, if necessary, clean your computer more frequently.

For your safety and to maintain optimum computer performance, always follow these basic precautions  
with your desktop computer:  
• Keep the cover closed whenever the computer is plugged in.  
• Regularly inspect the outside of the computer for dust accumulation.  
• Remove dust from vents and any perforations in the bezel. More frequent cleanings might be required for  
computers in dusty or high-traffic areas.  
• Do not restrict or block any ventilation openings.  
• Do not store or operate your computer inside furniture, as this might increase the risk of overheating.  
• Airflow temperatures into the computer should not exceed 35°C (95°F).  
• Do not install air filtration devices. They may interfere with proper cooling.  
Operating environment  
The optimal environment in which to use your computer is 10°C-35°C (50°F-95°F) with humidity ranging  
between 35% and 80%. If your computer is stored or transported in temperatures less than 10°C (50°F),  
allow the cold computer to rise slowly to an optimal operating temperature of 10°C-35°C (50°F-95°F) before  
use. This process could take two hours in extreme conditions. Failure to allow your computer to rise to an  
optimal operating temperature before use could result in irreparable damage to your computer.  
If possible, place your computer in a well-ventilated and dry area without direct exposure to sunshine.  
Keep electrical appliances such as an electric fan, radio, high-powered speakers, air conditioner, and  
microwave oven away from your computer because the strong magnetic fields generated by these  
appliances can damage the monitor and data on the hard disk drive.  
Do not place any beverages on top of or beside the computer or other attached devices. If liquid is spilled on  
or in the computer or an attached device, a short circuit or other damage might occur.  
Do not eat or smoke over your keyboard. Particles that fall into your keyboard can cause damage.  
Modem safety information  
CAUTION:  
To reduce the risk of fire, use only No. 26 AWG or larger (for example, No. 24 AWG) telecommunication  
line cord listed by Underwriters Laboratories (UL) or certified by the Canadian Standards Association  
(CSA).  
To reduce the risk of fire, electrical shock, or injury when using telephone equipment, always follow basic  
safety precautions, such as:  
• Never install telephone wiring during a lightning storm.  
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.  
• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at  
the network interface.  
• Use caution when installing or modifying telephone lines.  
• Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote  
risk of electric shock from lightning.  
• Do not use the telephone to report a gas leak in the vicinity of the leak.

Chapter 3. You and your computer  
This chapter provides information about accessibility, comfort, and relocating your computer to other  
countries or regions.  
Accessibility and comfort  
Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort.  
Arrange your workplace and the equipment you use to suit your individual needs and the kind of work  
that you perform. In addition, use healthy work habits to maximize your performance and comfort while  
using your computer.  
The following topics provide information about arranging your work area, setting up your computer  
equipment, and establishing healthy work habits:  
Lenovo is committed to providing people with disabilities greater access to information and technology.  
As a result, the following information provides ways to help users that have hearing, vision, and mobility  
limitations get the most out of their computer experience.  
Assistive technologies enable users to access information in the most appropriate way. Some of these  
technologies are already provided in your operating system, others can be purchased through vendors, or  
accessed through the World Wide Web:  
http://www.lenovo.com/healthycomputing  
Arranging your workspace  
To get the most from your computer, arrange both the equipment you use and your work area to suit your  
needs and the kind of work you do. Your comfort is of foremost importance, but light sources, air circulation,  
and the location of electrical outlets can also affect the way you arrange your workspace.  
Comfort  
Although no single working position is ideal for everyone, here are a few guidelines to help you find a  
position that suits you best.  
Sitting in the same position for a long time can cause fatigue. The backrest and seat of your chair should  
adjust independently and provide good support. The seat should have a curved front to relieve pressure on  
the thighs. Adjust the seat so that your thighs are parallel to the floor and your feet are either flat on the  
floor or on a footrest.  
When using the keyboard, keep your forearms parallel to the floor and your wrists in a comfortable position.

Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the monitor at a  
comfortable viewing distance, usually 51 to 61 cm (20 to 24 inches), and position it so you can view it  
without having to twist your body. Also, position other equipment you use regularly, such as the telephone or  
a mouse, within easy reach.  
Glare and lighting  
Position the monitor to minimize glare and reflections from overhead lights, windows, and other light sources.  
Reflected light from shiny surfaces can cause annoying reflections on your monitor screen. Place the  
monitor at right angles to windows and other light sources, when possible. Reduce overhead lighting, if  
necessary, by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use  
curtains or blinds to block the sunlight. You can adjust the brightness and contrast controls on the monitor  
as the room lighting changes throughout the day.  
Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen  
might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after  
you have exhausted other methods of reducing glare.  
Dust buildup compounds problems associated with glare. Remember to clean your monitor screen  
periodically using a soft cloth as directed in your monitor documentation.  
Air circulation  
Your computer and monitor produce heat. The computer has a fan that pulls in fresh air and forces out hot  
air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might  
result in a malfunction or damage. Place the computer and monitor so that nothing blocks the air vents;  
usually, 51 mm (2 inches) of air space is sufficient. Also, make sure the vented air is not blowing on people.  
Electrical outlets and cable lengths  
The location of electrical outlets, the length of power cords and cables that connect to the monitor, printer,  
and other devices might determine the final placement of your computer.  
When arranging your workspace:  
• Avoid the use of extension cords. When possible, plug the computer power cord directly into an electrical  
outlet.  
• Keep power cords and cables neatly routed away from walkways and other areas where they might  
get kicked accidentally.  
For more information about power cords, see “Power cords and power adapters” on page vi.

•
“Voltage-selection switch” on page 29  
“Replacement power cords” on page 30  
Voltage-selection switch  
Some computers are equipped with a voltage-selection switch located near the power-cord connection  
point on the computer and some computers do not have a voltage-selection switch. Before you install  
your computer or relocate your computer to another country or region, you must be certain that you have  
matched your computer to the voltage available at your electrical outlet.  
CAUTION:  
You must know the voltage of the electrical connection (outlet) where your computer will be  
connected. If you do not know the voltage, contact your local electric company or refer to official  
Web sites or other literature for travelers to the country or region where you are located.  
If your computer has a voltage-selection switch, you must set the switch to match the voltage available at  
your electrical outlet. Setting the voltage-selection switch incorrectly will cause the computer to malfunction  
and might cause permanent damage to the computer. Do not connect the computer to an electrical  
outlet until you have verified that the voltage-selection switch setting matches the voltage available at the  
electrical outlets.  
If your computer does not have a voltage-selection switch, inspect the voltage-rating label on the bottom of  
the computer and note the following:  
• If the voltage-rating label shows a range of either “100-127 V” or “200-240 V,” you must ensure that the  
voltage provided at the electrical outlet matches the voltage rating on the computer label. If it does  
not match, do not attempt to connect the computer to the electrical outlet, unless an external device  
such as a voltage-converting transformer is used.  
• If the voltage-rating label shows a dual range of “100-127 V” and “200-240 V,” this signifies that the  
computer is suitable for worldwide operation and the computer will automatically adjust to the voltage at  
the electrical outlet regardless of the country or region where the computer is being connected.

Chapter 5. Installing or replacing hardware  
This chapter provides instructions on how to install or replace hardware for your computer.  
Handling static-sensitive devices  
Do not open the static-protective package containing the new part until the defective part has been removed  
from the computer and you are ready to install the new part. Static electricity, although harmless to you, can  
seriously damage computer components and parts.  
When you handle parts and other computer components, take these precautions to avoid static-electricity  
damage:  
• Limit your movement. Movement can cause static electricity to build up around you.  
• Always handle parts and other computer components carefully. Handle PCI cards, memory modules,  
system boards, and microprocessors by the edges. Never touch any exposed circuitry.  
• Prevent others from touching the parts and other computer components.  
• Before you replace a new part, 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 from the package and your body.  
• When possible, remove the new part from the static-protective packaging, and install it directly in the  
computer without setting the part down. When this is not possible, place the static-protective package  
that the part came in on a smooth, level surface and place the part on it.  
• Do not place the part on the computer cover or other metal surface.

Creating and using recovery media  
You can use recovery media to restore the hard disk drive to the factory default state. Recovery media are  
useful if you transfer the computer to another area, sell the computer, recycle the computer, or put the  
computer in an operational state after all other methods of recovery have failed. As a precautionary measure,  
it is important to create recovery media as early as possible.  
Note: The recovery operations you can perform using recovery media vary depending on the operating  
system from which the recovery media were created. The recovery media might contain a boot medium  
and a data medium. Your Microsoft Windows license permits you to create only one data medium, so it is  
important that you store the recovery media in a safe place after you have made them.

Note: After restoring your computer hard disk drive to the factory default state, you might have to reinstall  
device drivers for some devices. See “Reinstalling device drivers” on page 86.  
Performing backup and recovery operations  
The Rescue and Recovery program enables you to back up all your hard disk drive contents including the  
operating system, data files, software programs, and personal settings. You can designate where the  
Rescue and Recovery program stores the backup:  
• In a protected area of your hard disk drive  
• On the secondary hard disk drive if a secondary hard disk drive is installed in your computer  
• On an attached external USB hard disk drive  
• On a network drive  
• On recordable discs (a recordable optical drive is required for this option)  
After you have backed up the contents of the hard disk drive, you can restore the complete contents of the  
hard disk drive, restore selected files only, or restore the Windows operating system and applications only  
while keeping the other data on your hard disk drive.

Using the Rescue and Recovery workspace  
The Rescue and Recovery workspace resides in a protected, hidden area of your hard disk drive that  
operates independently from the Windows operating system. This enables you to perform recovery  
operations even if you cannot start the Windows operating system. You can perform the following recovery  
operations from the Rescue and Recovery workspace:  
• Rescue files from your hard disk drive or from a backup: The Rescue and Recovery workspace enables  
you to locate files on your hard disk drive and transfer them to a network drive or other recordable media,  
such as a USB device or a disc. This solution is available even if you did not back up your files or if  
changes were made to the files since your last backup operation. You can also rescue individual files from  
a Rescue and Recovery backup located on your local hard disk drive, a USB device, or a network drive.  
• Restore your hard disk drive from a Rescue and Recovery backup: If you have backed up your hard disk  
drive using the Rescue and Recovery program, you can restore the hard disk drive from a Rescue and  
Recovery backup, even if you cannot start the Windows operating system.  
• Restore your hard disk drive to the factory default state: The Rescue and Recovery workspace enables  
you to restore the complete contents of your hard disk drive to the factory default state. If you have  
multiple partitions on your hard disk drive, you have the option to restore the C: partition and leave the  
other partitions intact. Because the Rescue and Recovery workspace operates independently from  
the Windows operating system, you can restore the hard disk drive to the factory default state even if  
you cannot start the Windows operating system.  
Attention: If you restore the hard disk drive from a Rescue and Recovery backup or restore the hard disk  
drive to the factory default settings, all files on the primary hard disk drive partition (usually drive C:) will be  
deleted in the recovery process. If possible, make copies of important files. If you are unable to start the  
Windows operating system, you can use the rescue files feature of the Rescue and Recovery workspace to  
copy files from your hard disk drive to other media.  
To start the Rescue and Recovery workspace, do the following:  
1. Make sure the computer is turned off.

© Copyright Lenovo 2013  
89  
Download from Www.Somanuals.com. All Manuals Search And Download.  
               
• Power-On Password  
• Administrator Password  
• Hard Disk Password  
You do not have to set any passwords to use your computer. However, using passwords improves  
computing security. If you decide to set any passwords, read the following sections.  
Password considerations  
A password can be any combination of up to 64 alphabetic and numeric characters. For security reasons, it  
is recommended to use a strong password that cannot be easily compromised. To set a strong password,  
use the following guidelines:  
• Have at least eight characters in length  
• Contain at least one alphabetic character and one numeric character  
• Setup Utility program and hard disk passwords are not case sensitive  
• Not be your name or your user name  
• Not be a common word or a common name  
• Be significantly different from your previous passwords  
Power-On Password  
When a Power-On Password is set, you are prompted to type a valid password each time the computer is  
turned on. The computer cannot be used until the valid password is typed in.  
Administrator Password  
Setting an Administrator Password deters unauthorized users from changing configuration settings. If you  
are responsible for maintaining the configuration settings of several computers, you might want to set an  
Administrator Password.  
When an Administrator Password is set, you are prompted to type a valid password each time you try to  
access the Setup Utility program. The Setup Utility program cannot be accessed until a valid password  
is typed in.  
If both the Power-On Password and Administrator Password are set, you can type either password. However,  
you must use your Administrator Password to change any configuration settings.  
Hard Disk Password  
Setting a Hard Disk Password prevents unauthorized access to the data on the hard disk drive. When a  
Hard Disk Password is set, you are prompted to type a valid password each time you try to access the  
hard disk drive.  
Notes:  
• After you set a Hard Disk Password, your data on the hard disk drive is protected even if the hard disk  
drive is removed from one computer and installed in another.  
• If the Hard Disk Password is forgotten, there is no way to reset the password or recover data from the  
hard disk drive.  
Setting, changing, and deleting a password  
To set, change, or delete a password, do the following:

Chapter 8. Updating system programs  
This chapter provides information about updating the POST and BIOS, and how to recover from a POST  
and BIOS update failure.  
Using system programs  
System programs are the basic layer of software built into your computer. System programs include the  
POST, the BIOS, and the Setup Utility program. The POST is a set of tests and procedures that are  
performed each time you turn on your computer. The BIOS is a layer of software that translates instructions  
from other layers of software into electrical signals that the computer hardware can execute. You can use  
the Setup Utility program to view or change the configuration settings of your computer. See Chapter 7  
“Using the Setup Utility program” on page 89 for detailed information.  
Your computer system board has a module called electrically erasable programmable read-only memory  
(EEPROM, also referred to as flash memory). You can easily update the POST, the BIOS, and the Setup  
Utility program by starting your computer with a system-program-update disc or running a special update  
program from your operating system.  
Lenovo might make changes and enhancements to the POST and BIOS. When updates are released, they  
are available as downloadable files on the Lenovo Web site at http://www.lenovo.com. Instructions for using  
the POST and BIOS updates are available in a TXT file that is included with the update files. For most  
models, you can download either an update program to create a system-program-update disc or an update  
program that can be run from the operating system.  
Updating (flashing) the BIOS from a disc  
This section provides instructions on how to update (flash) the BIOS from a disc.  
Note: You can download a self-starting bootable disc image (known as an ISO image) with the system  
program updates to create a system-program-update disc. Go to:  
http://www.lenovo.com/support  
To update (flash) the BIOS from a disc, do the following:  
1. Turn off your computer.  
2. Repeatedly press and release the F12 key when turning on the computer. When the Startup Device  
Menu opens, release the F12 key.  
3. On the Startup Device Menu, select the desired optical drive as the startup device. Then, insert the  
disc into this optical drive and press Enter. The update begins.  
4. When prompted to change the serial number, it is suggested that you do not make this change by  
pressing N. However, if you do want to change the serial number, press Y, then type in the serial number  
and press Enter.  
5. When prompted to change the machine type and model, it is suggested that you do not make this  
change by pressing N. However, if you do want to change the machine type and model, press Y, then  
type in the machine type and model and press Enter.

Using System Update  
The System Update program helps you keep the software on your computer up-to-date. Update packages  
are stored on Lenovo servers and can be downloaded from the Lenovo Support Web site. Update packages  
can contain applications, device drivers, BIOS flashes, or software updates. When the System Update  
program connects to the Lenovo Support Web site, the System Update program automatically recognizes  
the machine type and model of your computer, the installed operating system, and the language of the  
operating system to determine what updates are available for your computer. The System Update program  
then displays a list of update packages and categorizes each update as critical, recommended, and  
optional to help you understand the importance. You have complete control of which updates to download  
and install. After you select the update packages you want, the System Update program automatically  
downloads and installs the updates without any further intervention from you.  
The System Update program is preinstalled on most Lenovo computers and is ready to run. The only  
prerequisite is an active Internet connection. You can start the program manually, or you can use the  
schedule feature to enable the program to search for updates automatically at specified intervals. You also  
can predefine scheduled updates to search by severity (critical updates, critical and recommended updates,  
or all updates) so the list you choose from contains only those update types that are of interest to you.  
To open the System Update program, see “Accessing Lenovo programs on the Windows 7 operating system”  
on page 5 or “Accessing Lenovo programs on the Windows 8 or Windows 8.1 operating system” on page 7.  
If the System Update program is not currently installed on your computer, you can download it from the  
Lenovo Support Web site at http://www.lenovo.com/support.

Cleaning your computer  
It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free  
operation.  
CAUTION:  
Be sure to turn off the computer and monitor power switches before cleaning the computer and  
monitor screen.  
Computer  
Use only mild cleaning solutions and a damp cloth to clean the painted surfaces of the computer.  
Keyboard  
To clean your computer keyboard, do the following:  
1. Apply some isopropyl rubbing alcohol to 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. To remove any crumbs or 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 onto the display or the keyboard.  
Optical mouse  
This section provides instructions on how to clean an optical mouse.  
An optical mouse uses a light-emitting diode (LED) and an optical sensor to navigate the pointer. If the  
pointer on the screen does not move smoothly with the optical mouse, you might need to clean the mouse.  
To clean an optical mouse, do the following:  
1. Turn off your computer.  
2. Disconnect the mouse cable from the computer.  
3. Turn the mouse upside down to check the lens.  
a. If there is a smudge on the lens, gently clean the area with a plain cotton-tipped swab.  
b. If there is debris in the lens, gently blow the debris away from the area.  
4. Check the surface on which you are using the mouse. If you have a very intricate picture or pattern  
beneath the mouse, it may be difficult for the digital signal processor (DSP) to determine changes  
in the mouse position.  
5. Reconnect the mouse cable to the computer.  
6. Turn your computer back on.  
Display screen  
Dust buildup compounds problems associated with glare. Remember to clean your monitor screen  
periodically. See “Cleaning a flat-panel monitor surface” on page 99 or “Cleaning a glass-screen surface” on  
page 100.  
Cleaning a flat-panel monitor surface  
If you have a flat-panel computer display that has a flexible film surface, do the following to clean the special  
surface. Wipe it gently with a soft, dry cloth, or blow on the screen to remove grit and other loose particles.  
Then moisten a cloth with LCD cleaner and wipe the screen surface.  
Chapter 9. Preventing problems  
Download from Www.Somanuals.com. All Manuals Search And Download.  
99  
             
Many computer supply stores carry the special cleaning fluids for displays. Use cleaning fluids developed for  
LCD displays only. First apply the fluid to a lint-free, soft cloth, then clean the LCD display. Some computer  
supply stores carry pre-moistened towelettes for LCD maintenance.  
Cleaning a glass-screen surface  
To clean a glass-screen surface, wipe it gently with a soft, dry cloth, or blow on the screen to remove grit and  
other loose particles. Then use a soft cloth moistened with a nonabrasive liquid glass cleaner.  
Good maintenance practices  
By performing a few good maintenance practices, you can maintain good computer performance, protect  
your data, and be prepared in case of a computer failure.  
• Empty your recycle bin on a regular basis.  
• Run the Windows Disk Defragmenter program occasionally to prevent performance problems caused by  
an excessive number of fragmented files.  
• Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis.  
• Make backup copies of critical data on removable media memory at regular intervals and store the  
removable media in a safe location. The frequency of making backup copies depends on how critical the  
data is to you or your business. Lenovo makes a number of removable-media storage devices available  
as options, such as CD-RW drives and recordable DVD drives.  
• Back up your entire hard disk drive on a regular basis.  
• Keep your computer software up-to-date. See “Keeping your computer current ” on page 97 for more  
information.  
• Keep a log book. Entries might include major software or hardware changes, device-driver updates,  
intermittent problems and what you did to resolve them, and any minor issues you might have  
experienced. A log book can help you or a Lenovo technician determine if a problem is related to change  
in hardware, change in software, or some other action that might have taken place.  
• Create Product Recovery discs. See “Creating and using recovery media” on page 81 for more information  
about using Product Recovery discs to restore the hard disk drive to the factory default settings.  
• Create rescue media. See “Creating and using a rescue medium” on page 84 for more information about  
using a Rescue medium such as a CD or DVD to recover from failures that prevent you from gaining  
access to the Windows environment or the Rescue and Recovery workspace on your hard disk drive.  
Moving your computer  
Take the following precautions before moving your computer.  
1. Back up all files and data from the hard disk drive. There are a variety of backup programs available  
commercially. Your operating system also might have a backup program that you can use. Lenovo  
provides the Rescue and Recovery program to help you back up and restore data. See “Performing  
backup and recovery operations” on page 82 for more information.  
2. Remove all media (diskettes, compact discs, tapes, and so on) from the drives.  
3. Turn off the computer and all attached devices. Your hard disk drive automatically parks the read/write  
head in a nondata area. This prevents damage to the hard disk drive.  
4. Unplug the power cords from electrical outlets.  
5. Disconnect communication cables, such as modem or network cables, from the outlets first, and then  
disconnect the other ends from the computer.  
6. Note where any remaining cables are attached to the computer; then, remove them.  
7. If you saved the original shipping cartons and packing materials, use them to pack the units. If you are  
using different cartons, cushion the units to avoid damage.

or memory, you might have a memory-address conflict.)  
– The software is designed to operate on your computer.  
– Other software works on your computer.  
– The software you are using works correctly on another computer.  
• If you received any error messages while using the software program, see the printed documentation  
supplied with the software or the help system for that software for a description of the messages and  
solutions to the problem.  
• Check with your software manufacturer to see if any updates are available. Many software manufacturers  
make updates available from the World Wide Web.  
• If the software program used to work correctly, but does not work correctly now, do the following:  
– On the Windows 7 operating system, click Start ➙ Control Panel ➙ System and Security ➙ System  
➙ System Protection ➙ System Restore. Then, follow the instructions on the screen.

Important WEEE information  
The WEEE marking on Lenovo products applies to countries with WEEE and e-waste regulations (for example,  
European Directive 2002/96/EC, India E-Waste Management & Handling Rules, 2011). Appliances are  
labeled in accordance with local regulations concerning waste electrical and electronic equipment (WEEE).  
These regulations determine the framework for the return and recycling of used appliances as applicable  
within each geography. This label is applied to various products to indicate that the product is not to be  
thrown away, but rather put in the established collection systems for reclaiming these end of life products.  
Users of electrical and electronic equipment (EEE) with the WEEE marking must not dispose of end of  
life EEE as unsorted municipal waste, but use the collection framework available to them for the return,  
recycle, and recovery of WEEE and to minimize any potential effects of EEE on the environment and  
human health due to the presence of hazardous substances. For additional WEEE information go to:

Some Lenovo computer products sold in Japan may have components that contain heavy metals or other  
environmental sensitive substances. To properly dispose of disused components, such as a printed circuit  
board or drive, use the methods described above for collecting and recycling a disused computer or monitor.  
Disposing of disused lithium batteries from Lenovo computers  
A button-shaped lithium battery is installed on the system board of your Lenovo computer to provide power  
to the computer clock while the computer is off or disconnected from the main power source. If you want to  
replace it with a new one, contact your place of purchase or ask for a repair service provided by Lenovo. If  
you have replaced it by yourself and want to dispose of the disused lithium battery, insulate it with vinyl tape,  
contact your place of purchase, and follow their instructions. If you use a Lenovo computer at home and  
need to dispose of a lithium battery, you must comply with local ordinances and regulations.

Batteries or packaging for batteries are labeled in accordance with European Directive 2006/66/EC  
concerning batteries and accumulators and waste batteries and accumulators. The Directive determines the  
framework for the return and recycling of used batteries and accumulators as applicable throughout the  
European Union. This label is applied to various batteries to indicate that the battery is not to be thrown  
away, but rather reclaimed upon end of life per this Directive.  
In accordance with the European Directive 2006/66/EC, batteries and accumulators are labeled to indicate  
that they are to be collected separately and recycled at end of life. The label on the battery may also  
include a chemical symbol for the metal concerned in the battery (Pb for lead, Hg for mercury, and Cd for  
cadmium). Users of batteries and accumulators must not dispose of batteries and accumulators as unsorted  
municipal waste, but use the collection framework available to customers for the return, recycling, and  
treatment of batteries and accumulators. Customer participation is important to minimize any potential  
effects of batteries and accumulators on the environment and human health due to the potential presence of  
hazardous substances. For proper collection and treatment, go to:
