hazards and create a safer computer work environment.  
Note: This information includes references to power adapters and batteries. In  
addition to notebook computers, some products (such as speakers and  
monitors) ship with external power adapters. If you have such a product,  
this information applies to your product. In addition, computer products  
contain a coin-sized internal battery that provides power to the system clock  
even when the computer is unplugged, so the battery safety information  
applies to all computer products.  
Conditions that require immediate action  
Products can become damaged due to misuse or neglect. Some product damage  
is serious enough that the product should not be used again until it has been  
inspected and, if necessary, repaired by an authorized servicer.  
As with any electronic device, pay close attention to the product when it is  
turned on. On very rare occasions, you might notice an odor or see a puff of  
smoke or sparks vent from your product. Or you might hear sounds like  
popping, cracking, or hissing. These conditions might merely mean that an  
internal electronic component has failed in a safe and controlled manner. Or,  
they might indicate a potential safety issue. However, do not take risks or  
attempt to diagnose the situation yourself. Contact the Customer Support Center  
for further guidance. For a list of Service and Support phone numbers, refer to  
the safety and warranty information that is provided with your computer.  
Frequently inspect your computer and its components for damage, wear, or signs  
of danger. If you have any question about the condition of a component, do not  
use the product. Contact the Customer Support Center or the product  
manufacturer for instructions on how to inspect the product and have it  
repaired, if necessary.

General safety guidelines  
Always observe the following precautions to reduce the risk of injury and property  
damage.  
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 an ac power cord, always make sure that the power is turned  
off and that the product is unplugged from any power source. 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.  
vi User Guide

Danger  
Hazardous moving parts. Keep fingers and other body parts away.  
Attention  
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:  
v Limit your movement. Movement can cause static electricity to build up around  
you.  
v Always handle components carefully. Handle adapters, memory modules, and  
other circuit boards by the edges. Never touch exposed circuitry.  
v Prevent others from touching components.  
v 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.  
v When possible, remove the static-sensitive part from the static-sensitive  
packaging and install the part without setting it down. When this is not  
possible, place the static-sensitive packaging on a smooth, level surface and  
place the part on it.  
v 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.  
Voltage-selection switch  
Some computers are equipped with a voltage-selection switch located near the  
power-cord connection point on the computer. If your computer has a  
voltage-selection switch, ensure that you set the switch to match the voltage  
available at your electrical outlet. Setting the voltage-selection switch incorrectly  
can cause permanent damage to the computer.  
If your computer does not have a voltage-selection switch, your computer is  
designed to operate only at the voltage provided in the country or region where  
the computer was originally purchased.  
If you relocate your computer to another country, be aware of the following:  
v If your computer does not have a voltage-selection switch, do not connect the  
computer to an electrical outlet until you have verified that the voltage provided  
is the same as it was in the country or region where the computer was originally  
purchased.  
v If your computer has a voltage selection switch, do not connect the computer to  
an electrical outlet until you have verified that the voltage-selection switch is set  
to match the voltage provided in that country or region.  
viii User Guide

If you are not sure of the voltage provided at your electrical outlet, 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.  
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 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.  
Batteries  
All personal computers manufactured by Lenovo contain a non-rechargeable coin  
cell battery to provide power to the system clock. In addition, many mobile  
products, such as notebook computers, utilize a rechargeable battery pack to

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
provide system power when in portable mode. Batteries supplied by Lenovo for  
use with your product have been tested for compatibility and should only be  
replaced with approved parts.  
Never attempt to open or service any battery. Do not crush, puncture, or incinerate  
batteries or short circuit the metal contacts. Do not expose the battery to water or  
other liquids. Only recharge the battery pack strictly according to instructions  
included in the product documentation.  
Battery abuse or mishandling can cause the battery to overheat, which can cause  
gasses or flame to “vent” from the battery pack or coin cell. If your battery is  
damaged, or if you notice any discharge from your battery or the buildup of  
foreign materials on the battery leads, stop using the battery and obtain a  
replacement from the battery manufacturer.  
Batteries can degrade when they are left unused for long periods of time. For some  
rechargeable batteries (particularly Lithium Ion batteries), leaving a battery unused  
in a discharged state could increase the risk of a battery short circuit, which could  
shorten the life of the battery and can also pose a safety hazard. Do not let  
rechargeable Lithium-Ion batteries completely discharge or store these batteries in a  
discharged state.  
Heat and product ventilation  
Computers generate heat when turned on and when batteries are charging.  
Notebook computers can generate a significant amount of heat due to their  
compact size. Always follow these basic precautions:  
v Do not leave the base of your notebook 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 produces some heat during  
normal operation. Extended contact with the body could cause discomfort or,  
potentially, a skin burn.  
v Do not operate your computer or charge the battery near flammable materials or  
in explosive environments.  
v Ventilation slots, fans, and/ or 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.  
You should inspect your desktop computer for dust accumulation at least once  
every three months. Before inspecting your computer, turn off the power and  
unplug the computers power cord from the electrical outlet; then remove any dust  
from vents and perforations in the bezel. If you notice external dust accumulation,  
you should also 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 2 feet of high-traffic areas. If you must operate your computer in  
or near a high-traffic area, you should 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:  
v Keep the cover closed whenever the computer is plugged in.  
v Regularly inspect the outside of the computer for dust accumulation.

v Remove dust from vents and any perforations in the bezel. More frequent  
cleanings might be required for computers in dusty or high-traffic areas.  
v Do not restrict or block any ventilation openings.  
v Do not store or operate your computer inside furniture, as this might increase  
the risk of overheating.  
v Airflow temperatures into the computer should not exceed 35° C (95° F).  
v Do not use non-desktop air filtration devices.  
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.

Chapter 1. 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 also can 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. A good chair can  
make a big difference. The backrest and seat 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 neutral, comfortable position. Try to keep a light touch on the keyboard and  
your hands and fingers relaxed. You can change the angle of the keyboard for  
maximum comfort by adjusting the position of the keyboard feet.  
Viewing Distance  
Lower  
Back  
Support  
Seat  
Height  
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 in.),  
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. Even 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  
might have to 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 moistened with a nonabrasive liquid  
glass cleaner.  
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 in.) of air space is sufficient. Also, make sure the vented air is  
not blowing on someone else.  
Electrical outlets and cable lengths  
The location of electrical outlets and 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:  
v Avoid the use of extension cords. When possible, plug the computer power cord  
directly into an electrical outlet.  
v 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 viii and the safety and warranty information that is provided with your  
computer.

Chapter 2. Setting up your computer  
Before you begin, make sure you set up your computer in the best possible work  
area that suits your needs and the kind of work you do. For more information,  
Note: Read “Important safety information” on page v before you set up your  
computer. The precautions and guidelines will help you work safely.  
Connecting your computer  
Use the following information when connecting your computer. Look for the small  
connector icons on the back of your computer.  
Important  
Setting the voltage-selection switch incorrectly can cause permanent damage  
to the computer.  
If you are not sure of the voltage provided at your electrical outlet, 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.  
Note: Your computer might not have all of the switches or connectors described in  
this section.  
If your computer cables and connector panel have color-coded connectors, match  
the color of the cable end with the color of the connector. For example, match a  
blue cable end with a blue connector or a red cable end with a red connector.  
1. Some models are equipped with a voltage-selection switch located near the  
power-cord connection point on the computer.  
If your computer has a voltage-selection switch, ensure that you set the  
voltage-selection switch to match the voltage available at your electrical outlet.  
If necessary, use a ballpoint pen to slide the switch to a different position.  
v If the voltage supply range in your local country or region is 100–127 V ac,  
set the switch to 115 V.  
v If the voltage supply range is in your local country or region is 200–240 V  
ac, set the switch to 230 V.

Handling static-sensitive devices  
Static electricity, although harmless to you, can seriously damage computer  
components and options.  
When you add an option, do not open the static-protective package containing the  
option until you are instructed to do so.  
When you handle options and other computer components, take these precautions  
to avoid static electricity damage:  
v Limit your movement. Movement can cause static electricity to build up around  
you.  
v Always handle components carefully. Handle adapters and memory modules by  
the edges. Never touch any exposed circuitry.  
v Prevent others from touching components.  
v When you install a new option, touch the static-protective package containing  
the option 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.  
16 User Guide

Installing internal drives  
This section provides information and instructions for installing and removing  
internal drives.  
Internal drives are devices that your computer uses to read and store data. You can  
add drives to your computer to increase storage capacity and to enable your  
computer to read other types of media. Some of the different drives that are  
available for your computer are:  
v Serial Advanced Technology Attachment (SATA) hard disk drives  
v SATA Optical drives, such as CD drives or DVD drives  
v Removable media drives  
Note: These different drives are also referred to as integrated drive electronics  
(IDE) drives.  
Internal drives are installed in bays. In this book, the bays are referred to as bay 1,  
bay 2, and so on.  
When you install an internal drive, it is important to note what type and size of  
drive that you can install in each bay. Also, it is important to correctly connect the  
internal drive cables to the installed drive.

Creating and using the Product Recovery disc  
If your computer is equipped with a recordable CD or DVD drive, you can create a  
set of Product Recovery discs that enables you to restore the contents of the hard  
disk to the same state as when the computer was originally shipped from the  
factory. Product Recovery discs are useful if you transfer the computer to another  
area, sell the computer, recycle the computer, or as a last resort put the computer  
in an operational state after all other methods of recovery have failed. As a  
precautionary measure, it is important to create a set of Product Recovery discs as  
soon as possible.  
Note: The recovery operations you can perform using Product Recovery discs vary  
depending on the operating system from which they were created. Your  
Microsoft Windows license permits you to create only one set of Product  
Recovery discs, so it is important that you store the discs in a safe place  
after you make them.  
To create Product Recovery discs, do the following:  
1. From the Windows desktop, open the Start menu, select All Programs, select  
ThinkVantage, click Create Recovery Media.  
2. In the Recovery Discs section, select Create a set of Recovery Discs now.  
3. Follow the instructions on the screen.

Using the Rescue and Recovery workspace  
The Rescue and Recovery workspace resides in a protected, hidden area of your  
hard disk that operates independently from the Windows operating system. This  
enables you to perform recovery operations even if the Windows operating system  
cannot be started. You can perform the following recovery operations from the  
Rescue and Recovery workspace:  
v Rescue files from your hard disk or from a backup: The Rescue and Recovery  
workspace enables you to locate files on your hard disk and transfer them to a  
network drive or other recordable media, such as a USB hard disk drive or a  
diskette. 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 also can  
rescue individual files from a Rescue and Recovery backup located on your local  
hard disk, a USB device, or a network drive.

multiple partitions on your hard disk, you have the option to restore the factory  
contents to 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 factory contents even if you cannot start  
the Windows operating system.  
Attention: If you restore the hard disk from a Rescue and Recovery backup or  
restore the hard disk to the factory contents, all files on the primary hard disk  
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 in the Rescue and Recovery workspace to copy  
files from your hard disk to other media.

Chapter 6. Updating system programs  
This chapter contains information about updating POST/ BIOS and how to recover  
from a POST/ BIOS update failure.  
Using system programs  
System programs are the basic layer of software that is built into your computer.  
They include the power-on self-test (POST), the basic input/ output system (BIOS)  
code, and the Setup Utility program. POST is a set of tests and procedures that is  
performed each time you turn on your computer. BIOS is a layer of software that  
translates instructions from other layers of software into electrical signals that the  
computer hardware can understand. You can use the Setup Utility program to  
view and change the configuration and setup of your computer.  
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 POST, BIOS, and the Setup Utility program by starting your  
computer using a flash update diskette or by running a special update program  
from your operating system.  
Lenovo might make changes and enhancements to the POST/ 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/ 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 (flash)  
diskette or an update program that can be run from the operating system.  
Note: You can download a self starting bootable CD image (known as an .iso  
systems without a diskette drive.  
Updating (flashing) BIOS from a diskette or CD-ROM  
To update (flash) the BIOS from a diskette or CD-ROM, do the following:  
1. Insert a system program update (flash) diskette or CD-ROM into the diskette  
drive or optical drive. System program updates are available at  
http:/ / www.lenovo.com/ support on the World Wide Web.  
Note: If you are inserting a CD-ROM into the optical drive, make sure that the  
computer is turned on.  
2. Turn on the computer. If it is on already, you must turn it off and back on  
again. The update begins.  
3. When you are prompted to select a language, press the number on your  
keyboard that corresponds to the language and then press Enter.  
4. When prompted to change the serial number, press Y.  
5. Type in the seven character serial number of your computer and then press  
Enter.  
6. When prompted to change the machine type/ model, press Y.  
7. Type in the seven character machine type/ model of your computer and then  
press Enter.

b. If there is some 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.  
Non-optical mouse  
The non-optical mouse uses a ball to navigate the pointer. If the pointer on the  
screen does not move smoothly with the mouse, you might need to clean the  
mouse. Use the following procedure to clean the non-optical mouse:  
Note: The following illustration might be slightly different from your mouse.

7. Look for a build up of dirt on the plastic rollers ꢀ3ꢁ inside the ball cage. This  
build up usually appears as a stripe running across the middle of the rollers.  
8. If the rollers are dirty, clean them by using a cotton swab soaked in isopropyl  
(rubbing) alcohol. Turn the rollers with your finger and continue swabbing  
them until all the dirt is removed. Be sure the rollers are still centered in their  
channels after you clean them.  
9. Remove any fibers from the swab that might be remaining on the rollers.  
10. Replace the ball and the retainer ring. Twist the retainer ring to the locked  
position.  
11. Reconnect the mouse cable to the computer.  
12. Turn your computer back on.

Appendix A. Manual modem commands  
The following section lists commands for manually programming your modem.  
Commands are accepted by the modem while it is in Command Mode. Your  
modem is automatically in Command Mode until you dial a number and establish  
a connection. Commands can be sent to your modem from a PC running  
communication software or any other terminal devices.  
All commands sent to the modem must begin with AT and end with ENTER. All  
commands can be typed in either upper or lower case, but not mixed. To make the  
command line more readable, spaces can be inserted between commands. If you  
omit a parameter from a command that requires one, it is just like specifying a  
parameter of 0.

ATH [ENTER]
