Be sure to follow the important tips given here to continue to get the most use and enjoyment out of your  
computer. Failure to do so might lead to discomfort or injury, or cause your computer to fail.  
Protect yourself from the heat that your computer generates.  
When your computer is turned on or the battery is charging, the base, the palm  
rest, and some other parts may become hot. The temperature they reach  
depends on the amount of system activity and the level of charge in the battery.  
Extended contact with your body, even through clothing, could cause  
discomfort or even a skin burn.  
• Avoid keeping your hands, your lap, or any other part of your body in  
contact with a hot section of the computer for any extended time.  
• Periodically take hands from using the keyboard by lifting your hands from  
the palm rest.  
Protect yourself from the heat generated by the ac power adapter.  
When the ac power adapter is connected to an electrical outlet and your  
computer, it generates heat.  
Extended contact with your body, even through clothing, may cause a skin  
burn.  
• Do not place the ac power adapter in contact with any part of your body  
while it is in use.

Power cords and power adapters  
DANGER  
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 cords 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 pins 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.

General battery notices  
DANGER  
Personal computers manufactured by Lenovo contain a 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 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.  
Rechargeable battery notice  
DANGER  
Do not attempt to disassemble or modify the battery pack. Attempting to do so can cause an  
explosion, or liquid leakage from the battery pack. A battery pack other than the one specified by  
Lenovo, or a disassembled or modified battery pack is not covered by the warranty.  
If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion. The battery  
pack contains a small amount of harmful substances. To avoid possible injury:  
• Replace only with a battery of the type recommended by Lenovo.  
• Keep the battery pack away from fire.  
• Do not expose it to water or rain.  
• Do not attempt to disassemble it.  
• Do not short-circuit it.  
• Keep it away from children.  
• Do not drop the battery pack.  
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.  
The battery pack should be stored at room temperature, charged to approximately 30 to 50%  
of capacity. We recommend that battery pack be charged about once per year to prevent  
overdischarge.

even through clothing, could cause discomfort or even a skin burn. Periodically take breaks  
from using the keyboard by lifting your hands from the palm rest; and be careful not to use  
the keyboard for any extended length of time.  
• Do not operate your computer or charge the battery near flammable materials or in explosive  
environments.  
• 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.  
• When the ac power adapter is connected to an electrical outlet and your computer, it generates  
heat. Do not place the adapter in contact with any part of your body while using it. Never use the  
ac power adapter to warm your body. Extended contact with your body, even through clothing,  
may cause a skin burn.  
For your safety, always follow these basic precautions with your 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 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).

Access Connections  
The Access Connections™ program is a connectivity assistant program for creating and managing location  
profiles. Each location profile stores all the network and Internet configuration settings needed for connecting  
to a network infrastructure from a specific location such as a home or an office.  
By switching between location profiles as you move your computer from place to place, you can quickly and  
easily connect to a network with no need to reconfigure your settings manually and restart the computer  
each time.  
For instructions on accessing the Access Connections program, see “Accessing applications” on page 19.  
Active Protection System  
The Active Protection System program protects your hard disk drive when the shock sensor inside your  
computer detects a condition that could damage the drive, such as system tilt, excessive vibration, or shock.  
The hard disk drive is less vulnerable to damage when it is not operating. This is because when the hard disk  
drive is not operating, the system stops it from spinning, and may also move the read and write heads of the  
drive to areas that do not contain data. As soon as the shock sensor senses that the environment is stable  
again (minimal change in system tilt, vibration, or shock), it turns the hard disk drive on.  
For instructions on accessing the Active Protection System program, see “Accessing applications” on  
page 19.  
Fingerprint Software  
If your system comes with a fingerprint reader, the Fingerprint Software program enables you to enroll your  
fingerprint and associate it with your Windows® password. As a result, the fingerprint authentication can  
replace your password and enable simple and secure user access.  
For instructions on accessing the Fingerprint Software program, see “Accessing applications” on page 19.

Power management  
When you need to use your computer away from electrical outlets, you depend on battery power to keep  
your computer running. Different computer components consume power at different rates. The more you  
use the power-intensive components, the faster you consume battery power.  
Spend more time unplugged with ThinkPad batteries. Mobility has revolutionized business by allowing  
you to take your work wherever you go. With ThinkPad batteries, you will be able to work longer without  
being tied to an electrical outlet.

Checking battery status  
The Power Manager battery gauge on the taskbar displays the percentage of battery power remaining.  
The rate at which you use battery power will determine how long you can use the battery of your computer  
between charges. Because each computer user has different habits and needs, it is difficult to predict how  
long a battery charge will last. There are two main factors:  
• How much energy is stored in the battery when you begin to work.  
• The way you use your computer: how often you access the hard disk drive, how bright you make the  
computer display.  
Using the ac power adapter  
The power to run your computer can come either from the lithium-ion (Li-ion) battery pack provided with it,  
or from ac power through the ac power adapter. While you use ac power, the battery charges automatically.  
The ac power adapter that comes with your computer has two basic components:  
• The transformer pack that converts ac power adapter for use with the computer.  
• The power cord that plugs into the ac outlet and into the transformer pack.  
Attention: Using an improper power cord could cause severe damage to your computer.  
Connecting the ac power adapter  
To use the ac power adapter, do the following. Be sure to take these steps in the order in which they are  
given here.  
1. Connect the ac power adapter to the power jack of the computer.  
2. Connect the power cord to the transformer pack.  
3. Plug the power cord into an electrical outlet.  
Tips on using the ac power adapter  
• When the ac power adapter is not in use, disconnect it from the electrical outlet.  
• Do not bind the power cord tightly around the ac power adapter transformer pack when it is connected to  
the transformer.  
• Before you charge the battery, make sure that its temperature is at least 10 degrees Celsius (50 degrees  
Fahrenheit).  
• You can charge the battery when the ac power adapter is connected to the computer and the battery is  
installed. You need to charge it in any of the following conditions:  
– When you purchase a new battery  
– If the battery meter at the bottom of your display shows the battery charge is low  
– If the battery has not been used for a long time  
Charging the battery  
When you check battery status and find that the percentage of power remaining is low or when the power  
alarm alerts you that the remaining power is low, you need to charge your battery or replace it with a  
charged battery.  
If an ac outlet is convenient, plug the ac power adapter into it, and then insert the jack into the computer. The  
battery will charge in about 3 to 6 hours. This is affected by the battery size and the physical environment.

The battery status indicator will let you know that the battery is charging, and will also notify you when the  
battery is fully charged.  
Note: To increase the life of the battery, the computer does not start recharging the battery if the remaining  
power is greater than 95%.  
Maximizing battery life  
To maximize the life of the battery, do the following:  
• Use the battery until the charge is completely depleted; that is, use the battery until the battery status  
indicator starts blinking orange.  
• Recharge the battery completely before using it. The battery is fully charged if the battery indicator shows  
green when the ac power adapter is plugged in.  
• Always use power management features such as power modes, screen blank, sleep, and hibernation.  
Managing your battery power  
With Power Manager, you can adjust your power settings to give you the best balance between performance  
and power saving.  
For instructions on accessing the Power Manager program, see “Accessing applications” on page 19.  
For more information about the Power Manager program, refer to the Power Manager help information  
system.  
Power-saving modes  
There are several modes that you can use at any time to conserve power. This section introduces each  
mode and gives tips on the effective use of the battery power.  
Introducing the power-saving modes  
• Screen blank.  
The computer display requires considerable battery power. To turn off power to the display, do the  
following:  
1. Right-click the Power Manager battery gauge on the taskbar.  
2. Select Power off display.  
• Sleep.  
In sleep mode, your work is saved to memory, and then the hard disk drive and the computer display are

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 the latest information and technology to our customers with disabilities.  
Refer to our accessibility information which outlines our efforts in this area.  
Ergonomic information  
Working in the virtual office might 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.  
Note: This example shows someone in a conventional setting. Even when not in such a setting, you can  
follow many of these tips. Develop good habits, and they will serve you well.  
General posture: The following are some general recommendations for assuming a healthy working posture.  
It is best to periodically make minor modifications in your working posture to deter the onset of discomfort

caused by long periods of working in the same position. Frequent, short breaks from your work will also help  
to prevent any minor discomfort associated with your working posture.  
Display: Position the display to maintain a comfortable viewing distance of 510-760 mm (20-30 inch). Avoid  
glare or reflections on the display from overhead lighting or outside sources of light. Keep the display screen  
clean and set the brightness to levels that enable you to see the screen clearly. Press Fn+Home or End  
to adjust display brightness.  
Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.  
Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to  
best suit your desired posture.  
Arm and hand position: If available, utilize chair arm rests or an area on your working surface to provide  
weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)  
position. Type with a soft touch without pounding the keys.  
Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.  
What if you are traveling?  
It might 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?  
The visual display screens of ThinkPad notebook computers are 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.  
Adjusting your computer to fit you  
Refer to the following tips to improve performance and achieve greater comfort:  
Active sitting and rest breaks: The longer you sit and work with your computer the more important it is  
to observe your working posture. Following the instructions in “Ergonomic information” on page 49 and  
practicing “active sitting” are the best ways to avoid discomfort associated with your working postures.  
Making minor voluntary postural changes and taking short frequent work breaks are the key ingredients for  
healthy computing. Your computer is a light and mobile system; remember that it can easily be repositioned  
on your working surface to accommodate many posture modifications you might wish to make.  
Work area setup options: Familiarize yourself with all of your office furniture so that you know how to adjust  
your work surface, seat, and other work tools to accommodate your preferences for comfort. If your work  
area is not in an office setting, be sure to take special note of employing active sitting and utilizing work  
breaks. Note that there are many ThinkPad product solutions available to help you modify and expand  
your computer to best suit your needs. Access the following Web site to view some of these options:  
http://www.lenovo.com/accessories/services/index.html. Explore your options for docking solutions and  
external products that can provide the adjustability and features that you want.

your computer more comfortable to use.

Accessibility information  
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.  
Assistive technologies  
Some accessibility technologies are available through the Accessibility Options program. Depending  
on your operating system, the number of accessibility options available varies. In general, accessibility  
options enhance the way users with hearing, vision, or mobility limitations navigate and use their computer.  
For example, some users might not have the fine motor skills required to use a mouse or select key  
combinations. Other users might require larger fonts or high-contrast display modes. In some cases,  
magnifiers and built-in speech synthesizers are available. For detailed information about each of these  
features, consult the Microsoft help information system.  
To use the Accessibility Options program, click Start ➙ Control Panel ➙ Ease of Access ➙ Ease of  
Access Center.

Screen reader technologies are primarily focused on software application interfaces, help information  
systems, and a variety of online documents. However, in the case where a screen reader cannot read  
documents, the document must first go through a conversion process. One solution converts Adobe  
PDF files into a format that is read by the screen-reader programs. This solution is a Web-based service  
provided by Adobe Systems Incorporated. Through http://access.adobe.com, Adobe PDF documents can  
be converted to HTML or plain text in many languages. One conversion options converts PDF documents  
on the Internet. A second option enables users to submit the URL of an Adobe PDF file through e-mail to  
convert it to HTML or ASCII text. Adobe PDF files on a local hard disk drive, local CD-ROM, or LAN can also  
be converted by attaching the Adobe PDF file to an e-mail message.

no one else knows it. Then the administrator sets a user password for each computer in the network, and  
tells each user the password for his or her computer. The user can then change the user password as  
desired, but the administrator can still get access by using the master password.

unauthorized security attacks, several of the latest technologies and algorithms are integrated into UEFI  
BIOS and hardware design of ThinkPad notebook computers.  
To maximize security, do the following:  
1. Set a power-on password as well as a hard disk password for your internal hard disk drive. Refer to the  
procedures in “Power-on password” on page 54 and “Hard disk passwords” on page 55. For enhanced  
security, a strong password is recommended.  
2. If a Disk Encryption hard disk drive is installed in your computer, be sure to protect the contents of your  
computer memory from unauthorized access by use of drive encryption software.  
3. Before you dispose of, sell, or hand over your computer, make sure to delete data stored on it. Refer to  
“Notice on deleting data from your hard disk drive” on page 60.  
Note: The hard disk drive built into your computer can be protected by UEFI BIOS.  
Disk Encryption hard disk drive  
Some models contain the Disk Encryption hard disk drive. This feature helps to protect your computer  
against security attacks on media, NAND flash, or device controllers by use of a hardware encryption chip.  
For the efficient use of the encryption feature, be sure to set a password for the internal storage device.  
Refer to Hard disk passwords.  
Using a fingerprint reader  
Your computer might have an integrated fingerprint reader. Fingerprint authentication can replace passwords  
and enable simple and secure user access. By enrolling your fingerprint and associating it with a Windows  
password you can log on to the computer by swiping your finger over the reader, without typing passwords.  
Enrolling your fingerprint  
To use the integrated fingerprint reader, begin by enrolling your fingerprint as follows:  
1. Turn on your computer.  
2. To start the Lenovo Fingerprint software, refer to “Fingerprint Software” on page 21.  
58 User Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
       
3. Follow the instructions on the screen to enroll your fingerprint. For details, refer to the help information  
system for the program.  
Swiping your finger over the reader  
To swipe your finger over the reader, do the following:  
1. Place the ball of your finger (the central part of the fingerprint) on the small circle above the reader. Make  
sure that the entire top joint of the finger is on the reader.  
Note: Your computer keyboard might look different from the illustration above.  
2. Apply light pressure and swipe your finger across the reader in one smooth motion.  
Note: Your computer keyboard might look different from the illustration above.  
Maintaining the fingerprint reader  
The following actions could damage the fingerprint reader or cause it not to work properly:  
• Scratching the surface of the reader with a hard, pointed object.  
• Scraping the surface of the reader with your fingernail or anything hard.  
• Using or touching the reader with a dirty finger.  
Chapter 4. Security 59

If you notice any of the following conditions, gently clean the surface of the reader with a dry, soft, lint-free  
cloth:  
• The surface of the reader is dirty or stained.  
• The surface of the reader is wet.  
• The reader often fails to enroll or authenticate your fingerprint.  
If your finger has any of the following conditions, you might not be able to register or authenticate it:  
• Your finger is wrinkled.  
• Your finger is rough, dry, or injured.  
• Your finger is very dry.  
• Your finger is stained with dirt, mud, or oil.  
• The surface of your finger is very different from when you enrolled your fingerprint.  
• Your finger is wet.  
• A finger that has not been enrolled is used.  
To improve the situation, try the following:  
• Clean or wipe your hands to remove any excess dirt or moisture from the fingers.  
• Enroll and use a different finger for authentication.  
• If your hands are too dry, apply lotion to them.  
Notice on deleting data from your hard disk drive  
As computers spread into every corner of life, they process more and more information. The data on your  
computer, some of which is sensitive, is stored on a hard disk drive. Before you dispose of, sell, or hand over  
your computer, be sure to delete data stored on it.  
Handing your computer over to someone else without deleting the loaded software, such as operating  
systems and application software, may even violate License Agreements. You are advised to check the  
terms and conditions of those License Agreements.  
There are methods that seem to delete the data:  
• Move the data to the recycle bin, and then click Empty recycle bin.  
• Use the Delete option.  
• Format your hard disk drive, using the software for initializing it.  
• Using the recovery program, provided by Lenovo, bring the hard disk drive back to factory-ship state.  
These operations, however, only change the file allocation of the data; they do not delete the data itself. In  
other words, the data retrieval processing is disabled under an operating system such as Windows. The  
data is still there, even though it seems to be lost. Thus, it is sometimes possible to read the data by use of  
special software for data recovery. There is a risk that people of bad faith may read and misuse the critical  
data on hard disk drives for unexpected purposes.  
To prevent leakage of data, it becomes very important that you take responsibility for deleting all the data  
from the hard disk drive when you dispose of, sell, or hand over your computer. You can destroy the data  
physically by smashing the hard disk drive with a hammer, or magnetically by means of strong magnetic  
power, thus making the data unreadable. But we recommend that you make use of the software (payware) or  
service (pay service) specifically developed for the purpose.

For disposing of data on the hard disk drive, Lenovo provides the Secure Data Disposal tool. To download  
the application, go to:  
http://www.lenovo.com/support  
Note: Running the application will take a couple of hours.  
Using firewalls  
If your system is preintalled with a firewall program, it protects against computer Internet security threats,  
unauthorized access, intrusions, and Internet attacks. It also protects your privacy.  
For more information about how to use the firewall program, refer to the help information system that  
comes with the program.  
Protecting data against viruses  
Your computer is preinstalled with an antivirus program so you can detect and eliminate viruses. The  
antivirus program is designed to help you detect and eliminate viruses.  
Lenovo provides a full version of antivirus software on your computer with a free 30-day subscription. After  
30 days, you must renew the license to continue receiving the antivirus software updates.  
For more information about how to use your antivirus software, refer to the help information system of  
your antivirus software.

Creating and using recovery media  
You can use recovery media to restore the hard disk drive to the factory default settings. 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.

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 settings The Rescue and Recovery workspace  
enables you to restore the complete contents of your hard disk drive to the factory default settings. If you  
have multiple partitions on your hard disk drive, you have the option to restore the factory default settings  
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 default settings  
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:

when prompted for the device driver you want to install, click Have Disk and Browse. Then select  
the device driver file from the device subfolder.  
• In the subfolder for the device, look for the file for the application (a file with the extension .exe).  
Double-click the file, and follow the instructions on the screen.  
Attention: If you need updated device drivers, do not download them from the Windows Update Web site.  
Obtain them from Lenovo. For more information, see “Making sure device drivers are current” on page 108.  
Solving recovery problems  
If you are unable to access the Rescue and Recovery workspace or the Windows environment, do one  
of the following:  
• Use a rescue medium to start the Rescue and Recovery workspace. See “Using a rescue medium”  
on page 66.  
• Use recovery media if all other methods of recovery have failed and you need to restore the hard disk  
drive to the factory default settings. See “Using recovery media” on page 64.  
Note: If you are unable to access the Rescue and Recovery workspace or the Windows environment from  
a rescue medium or recovery media, you might not have the rescue device (an internal hard disk drive, a  
disc, a USB hard disk drive, or other external devices) set as the first boot device in the startup device  
sequence. You must first make sure that your rescue device is set as the first boot device in the startup  
device sequence in the ThinkPad Setup program. See “Startup menu” on page 98 for detailed information  
about temporarily or permanently changing the startup device sequence. For more information about the  
ThinkPad Setup program, see “ThinkPad Setup” on page 95.  
It is important to create a rescue medium and a set of recovery media as early as possible and store them  
in a safe place for future use.

Chapter 6. Replacing devices  
You can increase the capacity of the memory or the hard disk drive by replacing the original, built-in  
device with an optional one. Or, if you need to, you can replace the PCI Express Mini Card by following  
the procedures in this chapter.  
This chapter provides information on the following topics:

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  
a 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.

Updating your system UEFI BIOS  
The Unified Extensible Firmware Interface (UEFI) BIOS is a part of the system programs that make up the  
basic layer of software built into your computer. The UEFI BIOS translates the instructions from other  
software layers.  
Your computer system board has a module called electrically erasable programmable read-only memory  
(EEPROM, also referred to as flash memory). You can update the UEFI BIOS and the Configuration/ThinkPad  
Setup program by starting your computer with a flash update optical disc or flash update tool application  
running in the Windows environment.  
In some instances when you add software, hardware, or a device driver, you might be informed that you  
need to update your UEFI BIOS in order for the new addition to work properly.  
To update your UEFI BIOS, go to the following Web site and follow the instructions on the screen:

“Taking care of your computer” on page 108  
General tips for preventing problems  
1. Check the capacity of your hard disk drive from time to time. If the hard disk drive gets too full, Windows  
operating system will slow down and might produce errors. Click Start ➙ Computer.  
2. Empty your recycle bin on a regular basis.  
3. Use disk defragment tool regularly on your hard disk drive to improve data seek and read times.  
4. To free up disk space, uninstall unused application programs.  
Note: You might also want to look for application program duplication or overlapping versions.  
5. Clean out your Inbox, Sent, and Trash folders from your e-mail client program.  
6. back up your data at least once a week. If critical data is present, it is a good idea to perform a daily  
backup. Lenovo has many backup options available for your computer. Rewritable optical drives are  
available for most machines and can be installed easily.  
7. Use or schedule System Restore to take a system snapshot periodically. For more information about  
System Restore, see Chapter 5 “Recovery overview” on page 63.  
8. Update device drivers and UEFI BIOS when needed.  
9. Profile your machine at http://www.lenovo.com/support to keep up-to-date with current drivers and  
revisions.  
10. Keep up-to-date for 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.  
11. Keep a log book. Entries might include major hardware or software changes, driver updates, minor  
issues you have experienced and how you resolved them.  
12. If you ever need to run a recovery on your computer to return the preload onto the machine, the  
following tips might help along the way:  
• Remove all external devices such as the printer, keyboard, and so on.  
• Make sure that your battery is charged and that you have the ac power connected.  
• Boot into the UEFI and load the default settings.  
• Restart the machine and start the recovery.  
• If your machine uses discs as the recovery media, do not remove the disc from the drive until  
prompted to do so.  
13. For suspected hard disk drive issues, refer to “Diagnosing problems” on page 113 and run a  
diagnostic test of the drive before you call the Customer Support Center. If your computer does  
not start up, download the files to create a bootable self-test medium from the following Web site:  
http://www.lenovo.com/hddtest. Run the test and record any messages or error codes. If the test  
returns any failing error codes or messages, call the Customer Support Center with the codes or  
messages and the computer in front of you. A technician will assist you further.  
14. If required, you can find your country's Customer Support Center at the following Web address:  
http://www.lenovo.com/support/phone. When calling the Customer Support Center, make sure you

Download from Www.Somanuals.com. All Manuals Search And Download.  
     
have your machine model type, serial number and the computer 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.  
Making sure device drivers are current  
Device drivers are programs that contain instructions for the operating system about how to operate or  
“drive” a certain piece of hardware. Each hardware component on your computer has its own specific driver.  
If you add a new component, the operating system needs to be instructed on how to operate that piece  
of hardware. After you install the driver, the operating system can recognize the hardware component  
and understand how to use it.  
Note: Because drivers are programs, like any other file on your computer, they are susceptible to corruption  
and might not perform correctly if corruption occurs.  
It is not always necessary to download the latest drivers. However, you should download the latest driver  
for a component if you notice poor performance from that component or if you added a new component.  
This may eliminate the driver as the potential cause of the problem.  
Getting the latest drivers from the Web site  
You can download and install updated device drivers from the Lenovo Web site by doing the following:  
1. Connect to the Internet.  
2. Go to:  
http://www.lenovo.com/ThinkPadDrivers  
3. Find your computer entry and click it.  
4. Follow the directions on the screen and install the necessary software.  
Getting the latest drivers using System Update  
The System Update program helps you keep the software on your system 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, UEFI 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, or 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 your computer 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.  
For more information about how to use System Update, refer to “System Update” on page 23.  
Taking care of your computer  
Although 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  
DANGER  
Your computer has an Ethernet connector. To avoid the risk of electrical shock, do not connect  
the telephone cable to the Ethernet connector.  
• 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 inches).  
• 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.  
Note: Not all such appliances cause a significant electrostatic charge.  
Be gentle with your computer  
• Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.  
• 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.  
• Do not turn your computer over while the ac power adapter is plugged in. This could break the adapter  
plug.  
Carry your computer properly  
• Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect  
cords and cables.  
• When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by  
the display.  
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 the drive before closing the tray.  
• When installing the hard disk drive or optical drive, follow the instructions shipped with your hardware,  
and apply pressure only where needed on the device.  
• Turn off your computer if you are replacing the hard disk drive.  
• When replacing the primary hard disk drive, reattach the cover of the drive slot.  
Chapter 8. Preventing problems 109

• Store your external and removable hard disk or optical drives in the appropriate containers or packaging  
when they are not being used.  
• 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.  
– Memory module  
– PCI Express Mini Card  
– Memory card, such as SD card, SDHC card, SDXC card, and MultiMediaCard.  
Note: Not all listed devices are included in your computer.  
This action reduces any static electricity from your body. The static electricity could damage the device.  
• 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.  
Take care in setting passwords  
Remember your passwords. If you forget a supervisor or hard disk password, Lenovo will not reset it, and  
you might have to replace your system board or hard disk drive.  
Care for the fingerprint reader  
The following actions could damage the fingerprint reader or cause it not to work properly:  
• Scratching the surface of the reader with a hard, pointed object.  
• Scraping the surface of the reader with your fingernail or anything hard.  
• Using or touching the reader with a dirty finger.  
If you notice any of the following conditions, gently clean the surface of the reader with a dry, soft, lint-free  
cloth:

program installed, go to http://www.lenovo.com/diagnose for the latest information on diagnostics for your  
computer.  
Note: Running any test might take up to several minutes or longer. Make sure that you have time to run the  
entire test. Do not interrupt the test while it is running.  
Troubleshooting  
If your computer has an error, it typically displays a message or an error code, or a beep sounds when  
you turn it on. When you experience a problem, refer to the corresponding sections in this topic to try to  
solve the problem by yourself.  
Computer stops responding  
Print these instructions now and keep it with your computer for reference later.  
If your computer is completely unresponsive (you cannot use the UltraNav pointing device or the keyboard),  
do the following:  
1. Push and hold the power switch until the computer turns off. After the computer is turned off, restart by  
pressing the power switch. If it does not turn on, continue to step 2.  
Note: Do not remove the battery and ac power to reset the computer.  
2. While the computer is turned off, remove all power sources from the computer (battery and ac power).  
Hold down the power button for 10 seconds. Plug in the ac power while keeping the battery out of the  
computer. If the computer does not turn back on, continue to step 3.  
Note: Once the computer starts up and enters Windows environment, use the proper shutdown  
procedure to turn the computer off. Once the computer is off, reattach the battery and restart the  
computer. If the computer does not start with the battery reattached, remove the battery and again  
start with step 2. If the computer starts with ac power but does not start when the battery is attached,  
call the Customer Support Center for support.  
3. While the machine is off, remove all sources of power from the machine (battery and ac power). Remove  
all external devices that are attached to your computer (keyboard, mouse, printer, scanner, and so on.).  
Repeat step 2. If step 2 is unsuccessful, continue to step 4.  
Note: The following steps involve removing static sensitive components from your computer. Make sure  
that you are properly grounded and remove all sources of power attached to the computer. If you are  
uncomfortable or unsure about removing components, call the Customer Support Center for assistance.

If the computer still does not start up, call the Customer Support Center and a Customer Support specialist  
will assist you.  
Spills on the keyboard  
With a mobile computer, there are increased chances of spilling liquids on the keyboard. Because most  
liquids conduct electricity, liquid spilled on the keyboard could create numerous short circuits, potentially  
causing irreparable damage to your computer.  
If you spill something on your computer:  
Attention: Be sure that no liquid creates a short circuit between you and the ac power adapter (if in use).  
Although you might lose some data or work by turning off the computer immediately, leaving the computer  
on might make your computer unusable.  
1. Carefully unplug the ac power adapter immediately.  
2. Turn off the computer immediately. If the computer does not turn off, remove the battery. The more  
quickly you stop the current from passing through the computer the more likely you will reduce damage  
from short circuits.  
3. Wipe your computer dry with a paper towel.  
4. Before turning on your computer, make sure that all the liquid has dried.  
Note: If you want to replace your keyboard, contact the Customer Support Center. Refer to “Calling  
Lenovo” on page 135.

Due to the fact that integrated wireless cards operate within the guidelines found in radio frequency safety  
standards and recommendations, Lenovo believes they are safe for use by consumers. These standards and  
recommendations reflect the consensus of the scientific community and result from deliberations of panels  
and committees of scientists who continually review and interpret the extensive research literature.  
In some situation or environment, the use of integrated wireless cards may be restricted by the proprietor  
of the building or responsible representatives of the organization. These situations and areas may for  
example include:  
• Using the integrated wireless cards on board of airplanes, in hospitals or near petrol stations, blasting  
areas (with electro-explosive devices), medical implants or body-worn electronic medical devices, such  
as pace makers.  
• In any other environment where the risk of interference to other devices or services is perceived or  
identified as harmful.  
If you are uncertain of the policy that applies on the use of wireless devices in a specific organization  
(such as an airport or a hospital), you are encouraged to ask for authorization to use integrated wireless  
cards prior to turning on the computer.  
Location of the UltraConnect wireless antennas  
ThinkPad notebook computers feature an integrated diversity antenna system built into the display for  
optimal reception, enabling wireless communication wherever you are.
