Be sure to follow the important tips given here 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.  
• Never use it to warm your body.  
Prevent your computer from getting wet.  
To avoid spills and the danger of electrical shock, keep liquids away from your  
computer.  
Protect the cables from being damaged.  
Applying strong force to cables may damage or break them.  
Route communication lines, or the cables of an ac power adapter, a mouse, a  
keyboard, a printer, or any other electronic device, so that they cannot be walked  
on, tripped over, pinched by your computer or other objects, or in any way  
subjected to treatment that could interfere with the operation of your computer.

Protect your computer and data when moving it.  
Before moving a computer equipped with a hard disk drive, do one of the  
following, and ensure that the power button is off or is blinking:  
• Turn it off.  
• Put it in sleep mode.  
• Put it in hibernation mode.  
This will help to prevent damage to the computer, and possible loss of data.  
Handle your computer gently.  
Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on  
your computer, display, or external devices.  
Carry your computer carefully.  
• Use a quality carrying case that provides adequate cushioning and protection.  
• Do not pack your computer in a tightly packed suitcase or bag.  
• Before putting your computer in a carrying case, ensure that it is off, in sleep  
mode, or in hibernation mode. Do not put a computer in a carrying case while it  
is turned on.

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, see the following Web site:  
http://www.lenovo.com/support/phone  
Frequently inspect your computer and its components for damage or 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.  
In the unlikely event that you notice any of the following conditions, or if you have any safety concerns  
with your product, stop using the product and unplug it from the power source and telecommunication  
lines until you can speak to the Customer Support Center for further guidance.  
• Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are

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 a power cord, always ensure  
© Copyright Lenovo 2013  
vii  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
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.  
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.  
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.

To prevent possible overheating, do not cover the power adapter with clothing or other objects  
when the power adapter is plugged into an electrical outlet.  
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  
DANGER  
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.

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.  
General battery notice  
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 you notice any signs of bulging, leakage or corrosion  
on the exterior of the product, this may be the result of an internal battery fault. If this occurs, stop  
using the product immediately and please contact the Lenovo Support team for further instructions.  
Factory replacement of the batteries may be required.  
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.  
Built-in rechargeable battery notice  
DANGER  
Do not attempt to replace the internal rechargeable lithium ion batteries. Contact Lenovo Support

Lenovo programs overview  
This topic provides information about some Lenovo programs.  
Note: Depending on your computer model, some of the programs might not be available.  
• Access Connections  
14 User Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
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.  
• 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 might 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.  
• Client Security Solution  
The Client Security Solution program protects your computer by securing client data and deflecting  
security breach attempts. It also can help manage your passwords, recover a forgotten password,  
monitor security settings on your computer, and suggest how to enhance your computer security.  
• Communications Utility  
Use the Communications Utility program to configure settings for the integrated camera and audio devices.  
• 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.  
• Lenovo Companion  
Through the Lenovo Companion program, you can get the information about the accessories for your  
computer, view bolgs and articles about your computer, and check for other recommended programs.  
• Lenovo Mobile Access  
The Lenovo Mobile Access program enables you to manage your mobile broadband connection. You  
can create an account, add money to the account, and purchase mobile broadband sessions using  
your account.  
• Lenovo QuickSnip  
The Lenovo QuickSnip program provides you with a quick and easy way to capture and share your  
experience. It enables you to grab a screenshot, snip and save the screenshot, and use it in other  
applications.  
• Lenovo Settings  
Use the Lenovo Settings program to enhance your computing experience by turning your computer into  
a portable hotspot, configuring camera and microphone settings, optimizing your power settings, and  
creating and managing multiple network profiles.  
• Lenovo Solution  
The Lenovo Solution program enables you to troubleshoot and resolve computer problems. It combines  
diagnostic tests, system information collection, security status, and support information, along with  
hints and tips for maximum system performance.

Windows programs and Web sites.  
• Power Manager

computer. It enables you to adjust your computer power settings to achieve the best balance between  
performance and power saving.  
• Recovery Media

default settings.  
• Rescue and Recovery  
The Rescue and Recovery program is a one-button recovery and restore solution that includes a set of  
self-recovery tools to help you diagnose computer problems, get help, and recover from system crashes,  
even if you cannot start the Windows operating system.  
• SimpleTap  
The SimpleTap program provides you with a quick way to customize some basic computer settings such  
as muting the speakers, adjusting the volume, locking the computer operating system, launching a  
program, opening a Web page, opening a file, and so on. You also can use the SimpleTap program to

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. 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 the battery status  
The battery icon in the Windows notification area 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. For example:  
– How often you access the hard disk drive.  
– How bright you make the computer display.  
– How often you use the wireless features.  
To check for detailed battery status information, do the following:  
• For the Windows 7 operating system: Open the Power Manager program and click the Battery tab.  
• For the Windows 8 operating system:  
– Open the Lenovo Settings program and click Power.  
– Open the Lenovo Support program and click Battery Health.  
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.  
Chapter 2. Using your computer 25

The ac power adapter that comes with your computer has two basic components:  
• The transformer pack that converts ac power 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. Plug the ac power adapter into an ac outlet.  
2. Connect the power cord to the transformer pack.  
3. Insert the power jack into the computer.  
Tips on using the ac power adapter  
You can check the status of your battery at any time by looking at the battery meter at the bottom of your  
display.  
• 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, ensure that its temperature is at least 10°C (50°F).  
• 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.  
– The percentage of power remaining is low.  
– 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.  
If an ac outlet is convenient, plug the ac power adapter into it, and then insert the jack into the computer.  
The battery will be fully charged in about 3 to 6 hours. This is affected by the battery size and the physical  
environment.  
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 the battery life  
To achieve the best balance between performance and power saving, adjust your power plan settings.  
To access power plan settings, do the following:  
• Use the battery until the charge is completely depleted.  
• Recharge the battery completely before using it. You can see whether the battery is fully charged from the  
battery status icon in the Windows notification area.  
• Always use power management features such as power modes, screen blank, sleep, and hibernation.

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.  
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: 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 also help to prevent  
minor discomfort associated with your working posture.

Display: Position the display to maintain a comfortable viewing distance of 20-30 inches (510-760 mm).  
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 F5 or F6  
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, use 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.  
Comfort  
Observe the following guidelines to achieve greater comfort and improve performance.  
Active sitting and rest breaks: The longer you sit and work with your computer, the more important it is to  
observe your working posture. Follow “Ergonomic information” on page 39 and practice “active sitting” 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 light and  
mobile; you can easily reposition your working surface to accommodate many posture modifications.  
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 taking work breaks. Many ThinkPad product solutions are 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 provide the adjustability and features that you want.  
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  
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 option 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 also can  
be converted by attaching the Adobe PDF file to an e-mail message.  
Traveling with your computer

Notice on deleting data from your hard disk drive or solid-state drive  
As computers spread into every corner of life, they process more and more information. The data on your  
computer, some of which might be sensitive, is stored on a hard disk drive or solid-state 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, might 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 or solid-state drive, using the software for initializing it.  
• Using the recovery program, bring the hard disk drive or solid-state drive back to the factory default  
settings.  
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 might read and misuse the critical  
data on hard disk drives or solid-state 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 or solid-state drive when you dispose of, sell, or hand over your computer. You  
can destroy the data physically by smashing the hard disk drive or solid-state 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 or solid-state drive, Lenovo provides the Secure Data Disposal  
tool. To download the application, go to:  
http://www.lenovo.com/support  
Note: Running either application will take a couple of hours.  
Using firewalls  
If your system is preinstalled with a firewall program, it protects against computer Internet security threats,  
unauthorized accesses, 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.

Creating and using a 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.  
Creating recovery media  
This section provides instructions on how to create recovery media.  
Note: You can create recovery media using discs or external USB storage devices.

For more information about performing a recovery operation from the Rescue and Recovery workspace, see  
“Using the Rescue and Recovery workspace” on page 57.  
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 also can 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:  
1. Ensure that the computer is turned off.  
2. Repeatedly press and release the F11 key when turning on the computer. When you hear beeps or  
see a logo screen, release the F11 key.

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 the part.  
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 package and install the part  
without setting it down. When this is not possible, place the static-protective package on a smooth,  
level surface and place the part on the package.  
• Do not place the part on the computer cover or other metal surface.  
Disabling the built-in battery  
Before replacing any CRU, ensure that you have disabled the built-in battery by doing the following:  
1. Turn off your computer and disconnect the ac power adapter and all cables from the computer.  
2. Turn on your computer. Press F1 to enter ThinkPad Setup when the ThinkPad logo appears.  
3. Select Config ➙ Power. The Power submenu is displayed.  
4. Select Disable Built-in Battery.  
5. Click Yes in the Setup Warning window. Then the computer will automatically turned off. Wait three to  
five minutes to let the computer cool.

Replacing the backup battery  
Before you start, print these instructions.  
DANGER  
If the backup battery is incorrectly replaced, there is danger of an explosion. The backup battery  
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 excessive heat.  
• Do not expose it to water or rain.  
• Do not short-circuit it.  
• Do not drop, crush, puncture, or subject to strong forces. 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.  
To replace the backup battery, do the following:  
1. Disable the built-in battery. See “Disabling the built-in battery” on page 63.  
2. Close the computer display, and turn the computer over.  
3. Remove the base cover assembly. See “Replacing the base cover assembly” on page 64.

Installing a new operating system  
If you install a new operating system on your computer, you need to install the supplement files and  
ThinkPad device drivers for it at the same time.  
• If you install a new Windows 7 operating system, the necessary files are located in the following directories  
on your solid state-drive or hard disk drive:  
– The supplement files for the operating system supported are in the C:\SWTOOLS\OSFIXES directory.  
– The device drivers for the operating system supported are in the C:\SWTOOLS\DRIVERS directory.  
– The preloaded software applications are in the C:\SWTOOLS\APPS directory.  
Note: If you cannot find the supplement files, the device drivers, and application software you need on  
your hard disk drive, or if you want to receive updates and the latest information about them, go to:  
http://www.lenovo.com/Drivers

backups or images that were stored in a hidden folder by use of a recovery program.  
Before you begin  
Note: If your computer is equipped with both a hard disk drive and an M.2 solid-state drive, you are not  
recommended to use the M.2 solid-state drive as a bootable device. The M.2 solid-state drive is designed  
and developed for “cache” function purpose only. If you use the M.2 solid-state drive as a bootable device,  
its reliability is not guaranteed.  
Before you install the operating system, do the following:  
• If you are going to install a new Windows 7 operating system, copy all the subdirectories and files in the  
C:\SWTOOLS directory to a removable storage device, to avoid losing files during the installation.  
• Print the instructions you will use. Go to the section for the operating system you are using:

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 EEPROM, also referred to as flash memory. You can  
update the UEFI BIOS and the ThinkPad Setup program by starting your computer with a flash update  
optical disc or flash update 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:  
http://www.lenovo.com/Drivers  
Using system management  
This section is intended primarily for network administrators.  
Your computer is designed for manageability, so that you can redirect more of your resources to better  
meet your business objectives.  
This manageability, or “Total Cost of Ownership” (TCO), enables you to remotely operate client computers  
in the same way as you operate your own computer, such as turning on a client computer, formatting  
hard disk drive, and installing software.  
Once the computer is configured and operational, you can manage it by use of software and manageability  
features already integrated into the client system and the network.  
System management  
Read this topic to learn more about features of system management:  
Desktop Management Interface  
The system UEFI BIOS of your computer supports an interface called System Management BIOS Reference  
Specification (SMBIOS) V2.6.1 SMBIOS provides information about the hardware components of your  
system. It is the responsibility of the BIOS to supply this database with information about itself and the  
devices on the system board. This specification documents the standards for getting access to this BIOS  
information.  
Preboot eXecution Environment  
Preboot eXecution Environment (PXE) technology makes your computer more manageable (it is PXE  
2.1-compliant) by enabling it to boot (load an operating system or another executable image) from a  
88 User Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
server. Your computer supports the personal computer functions that PXE requires. For example, with the  
appropriate LAN card, your computer can be booted from the PXE server.  
Note: Remote Program Load (RPL) cannot be used with your computer.  
Wake on LAN  
A network administrator can use Wake on LAN to turn on a computer from a management console.  
When Wake on LAN is used with network management software, many functions, such as data transfer,  
software updates, and Flash updates of UEFI BIOS, can be performed remotely without remote attendance.  
This updating can be done after normal working hours and on weekends, to save time and increase  
productivity. Users are not interrupted during normal working hours, and LAN traffic is kept to a minimum.  
If a computer is turned on by the Wake on LAN function, the Network boot sequence is used.  
Asset ID EEPROM  
The Asset ID EEPROM contains information about the system, including its configuration and the serial  
numbers of key components. It also includes a number of blank fields in which you can record information  
about the end users in your network.  
Setting management features  
To enable the network administrator to control your computer remotely, you must configure the network  
interface by setting the system-management features in the ThinkPad Setup program. You can configure  
the following functions in the program:  
• Wake on LAN  
• Network Boot sequence  
• Flash update  
If an administrator password (supervisor password) has been set, you will need to specify it when you start  
ThinkPad Setup to use these functions.  
Wake on LAN  
When the Wake on LAN feature is enabled on a computer that is connected to a LAN, a network administrator  
can start the computer remotely from a management console, using remote network-management software.  
When your computer is not under the network administrator's system management, you can disable Wake  
on LAN.  
To enable or disable Wake on LAN, do the following:  
1. Start ThinkPad Setup.  
2. Select Config. The Config submenu is displayed.  
3. Select Network. The Network item submenu is displayed.  
4. For Wake On LAN, select one of the following: AC Only, AC and Battery, or Disabled.  
5. Press F10 to save changes and exit.  
Network Boot sequence  
When your computer is turned on remotely, the system will try to boot from the device that is specified in the  
Network Boot setting, and then follow the boot order list on the Boot menu.  
Chapter 7. Advanced configuration 89  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
To define a sequence, do the following:  
1. On the ThinkPad Setup program menu, select Startup. The submenu is displayed.  
2. Select Network Boot and press the Enter key. The boot device list is displayed.  
3. Select a boot device from the list to make it as the top boot priority.  
4. Press F10 to save changes and exit.  
Note: If you want to initialize the setting to return to the default startup sequence, press F9. The default  
settings are automatically reloaded.  
Flash update  
Your network administrator can remotely update the system programs on your computer from a management  
console. The following requirements must be met:  
• Your computer must be started over the LAN.  
• Your computer must be engaged in a Preboot eXecution Environment.  
• Network-management software must be installed on the remote administrator's computer.

An important part of owning a ThinkPad notebook computer is maintenance. With proper care, you can  
avoid common problems. The chapter provides information that can help you keep your computer running  
smoothly.

“Taking care of your computer” on page 93  
General tips for preventing problems  
1. If your computer is equipped with both a hard disk drive and an M.2 solid-state drive, you are not  
recommended to use the M.2 solid-state drive as a bootable device. The M.2 solid-state drive is  
designed and developed for “cache” function purpose only. If you use the M.2 solid-state drive as a  
bootable device, its reliability is not guaranteed.  
2. Check the capacity of your hard disk drive from time to time. If the hard disk drive gets too full, the  
Windows operating system will slow down and might produce errors. To check the hard disk drive  
capacity, do either of the following:  
• If your system is installed with the Windows 7 operating system, click Start ➙ Computer.  
• If your system is installed with the Windows 8 operating system, open Windows Explorer, and click  
Computer.  
3. Empty your recycle bin on a regular basis.  
4. Use disk defragment tool regularly on your hard disk drive to improve data seek and read times.  
5. To free up disk space, uninstall unused application programs.  
Note: You also might want to look for application program duplication or overlapping versions.  
6. Clean out your Inbox, Sent, and Trash folders from your e-mail client program.  
7. Back up your data at least once a week. If critical data is present, it is a good idea to perform a daily  
backup operation. Lenovo has many backup options available for your computer.  
8. Schedule system restore operations to take a system snapshot periodically. For more information about  
system restore, see Chapter 5 “Recovery overview” on page 55.  
9. Update device drivers and UEFI BIOS when needed.  
10. Profile your machine at http://www.lenovo.com/support to keep up to date with current drivers and  
revisions.  
11. 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.  
12. Keep a log book. Entries might include major hardware or software changes, driver updates, minor  
issues you have experienced, and how you resolved the minor issues.  
13. 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.  
• Ensure that your battery is charged and that you have the ac power connected.  
• Boot into ThinkPad Setup and load the default settings.  
• Restart the computer and start the recovery operation.  
• If your computer uses discs as the recovery media, do not remove the disc from the drive until  
prompted to do so.

14. For suspected hard disk drive issues, refer to “Diagnosing problems” on page 97 to 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 media 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.  
15. If required, you can find your country's Customer Support Center at:  
http://www.lenovo.com/support/phone. When calling the Customer Support Center, ensure that you  
have your machine model type, serial number, and the computer in front of you. Also, if the computer 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 might 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. Go to http://www.lenovo.com/Drivers.  
2. Enter the product number of the computer or click Detect my system on the screen.  
3. Click Downloads and drivers.  
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 “Lenovo programs overview” on page 14.

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  
• 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 might become electrostatically charged. Such a charge might 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  
• When installing the hard disk drive or M.2 solid-state 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 or the M.2 solid-state drive.  
• When replacing the hard disk drive, reattach the cover of the drive slot.  
• Store your external and removable hard disk drive 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  
– Mini PCI 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.  
• While transferring data to or from a media card, such as an SD card, do not put your computer into sleep  
or hibernation mode before the data transfer is completer; otherwise, your data could become damaged.  
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:  
• 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.  
Register your computer  
Register your ThinkPad computer with Lenovo at http://www.lenovo.com/register. This can help authorities  
return your computer to you if it is lost or stolen. Registering your computer also enables Lenovo to notify  
you about possible technical information and upgrades.  
Be sure not to modify your computer  
• Only an authorized ThinkPad repair technician should disassemble and repair your computer.  
• Do not modify or tape the latches to keep the display open or closed.  
Cleaning the cover of your computer  
Occasionally clean your computer by doing the following:  
1. Prepare a mixture of a gentle kitchen-use detergent (one that does not contain abrasive powder or  
strong chemicals such as acid or alkaline). Use 5 parts water to 1 part detergent.  
2. Absorb the diluted detergent into a sponge.  
3. Squeeze excess liquid from the sponge.  
4. Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip.  
5. Wipe the surface to remove the detergent.  
6. Rinse the sponge with clean running water.  
7. Wipe the cover with the clean sponge.

Cleaning your computer keyboard  
To clean the 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 might hook onto an adjacent key and possibly damage it. Ensure that no liquid drips onto  
or between the keys.  
3. Allow to dry.  
4. 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.  
Cleaning your computer display  
To clean the computer display, do the following:  
1. Gently wipe the display with a dry, soft lint-free cloth. If you see a scratchlike mark on your display,  
it might be a stain transferred from the keyboard or the TrackPoint pointing stick when the cover was  
pressed from the outside.  
2. Wipe or dust the stain gently with a soft, dry cloth.  
3. If the stain remains, moisten a soft, lint-free cloth with water or a 50-50 mixture of isopropyl alcohol and  
water that does not contain impurities.  
4. Wring out as much of the liquid as you can.  
5. Wipe the display again; do not let any liquid drip into the computer.  
6. Be sure to dry the display before closing it.

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: Ensure 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. Wait until you are certain that all the liquid is dry before turning on your computer.  
Note: If you want to replace your keyboard, you can purchase a new one.

applications are aware of the settings in the Volume Mixer window and are allowed to change the settings  
themselves. An example is the Windows Media Player. Usually the application has sliders available  
to control the sound from within the application.  
• Problem: The balance slider cannot completely mute one channel.  
Solution: The control is designed to compensate for minor differences in balance and does not  
completely mute either channel.  
• Problem: There is no volume control for MIDI sound in the Volume Mixer window.  
Solution: Use the hardware volume control. This is because the built-in synthesizer software does  
not support the control.  
• Problem: The sound cannot be turned off completely even if you set the Volume Mixer at minimum.  
Solution: You still can hear some sound even though you have set the Volume Mixer control at minimum.  
To turn off the sound completely, go to the Volume Mixer by clicking the speaker icon in the taskbar,  
then click Mixer. Click the Mute Speaker icon.  
• Problem: When you connect a headphone to your computer while playing sound, a speaker does not  
produce sound in the MULTI-STREAM mode at Realtek HD Audio Manager.  
Solution: Once the headphone is attached, the streaming is automatically redirected to it. If you want  
to listen to sound from the speakers again, be sure to set those speakers as the default device. The  
procedure is as follows:  
1. Open Control Panel. Click Hardware and Sound.  
2. Click the Realtek HD Audio Manager icon. The Realtek HD Audio Manager window opens.  
3. Look at the tabs of playback devices. If you have attached a headphone, the headphone will be  
automatically set as the default device, and the headphone tab icon will be checked.  
4. To set a different device as the default, click the speaker tab. Click the Set Default Device drop  
down list box. Select Set Default Device. That speaker tab icon will now have a check mark.  
5. Play any sound by use of a music program such as Windows Media Player. Ensure that sound  
comes from the speakers.  
For details, refer to the help information system for Realtek HD Audio Manager.  
Fingerprint reader problems  
• Problem: The surface of the reader is dirty, stained, or wet.  
Solution: Gently clean the surface of the reader with a dry, soft, lint-free cloth.  
• Problem: The reader often fails to enroll or authenticate your fingerprint.  
Solution: If the surface of the reader is dirty, stained, or wet, gently clean the surface of the reader

If the battery is charged and the temperature is within range, have the computer serviced.  
• Problem: A critical low-battery error occurs, and the computer immediately turns off.  
Solution: The battery power is getting low. Connect the ac power adapter to the computer and plug it  
into an electrical outlet.  
• Problem: The computer display remains blank after you press Fn to return from sleep mode.  
Solution: Check whether an external monitor was disconnected or turned off while the computer was  
in sleep mode. If you disconnected or turned off the external monitor, connect it or turn it on before  
resuming the computer from the sleep mode. When resuming the computer from the sleep mode  
without attaching the external monitor or turning it on, and the computer display remains blank, press  
F6 to bring up the computer display.  
• Problem: The computer does not return from sleep mode, or the system status indicator (illuminated  
ThinkPad logo) blinks slowly and the computer does not work.  
Solution: If the system does not return from sleep mode, it might have entered sleep or hibernation  
mode automatically because the battery is depleted. Check the system status indicator (illuminated  
ThinkPad logo).  
– If the system status indicator (illuminated ThinkPad logo) blinks slowly, your computer is in sleep mode.  
Connect the ac power adapter to the computer; then press Fn.  
– If the system status indicator (illuminated ThinkPad logo) is off, your computer is in power-off state or  
in hibernation mode. Connect the ac power adapter to the computer; then press the power button  
to resume operation.  
If the system still does not return from sleep mode, your system might stop responding and you might not  
be able to turn off the computer. In this case, you need to reset the computer. If you have not saved your  
data, it might be lost. To reset the computer, press and hold the power button for 4 seconds or more. If  
the system is still not reset, remove the ac power adapter and the battery.  
• Problem: Your computer does not enter sleep or hibernation mode.  
Solution: Check whether any option has been selected to disable your computer from entering sleep  
or hibernation mode.  
If your computer tries to enter sleep mode but the request is rejected, the device attached to the USB  
connector might have been disabled. If this occurs, do a hot-unplug-and-plug operation for the USB  
device.  
• Problem: The battery discharges slightly while the computer is in hibernation mode.  
Solution: If the wakeup function is enabled, the computer consumes a small amount of power. This is not  
a defect. For details, refer to “Power-saving modes” on page 27.

Usage environment and your health  
Integrated wireless cards emit radio frequency electromagnetic energy like other radio devices. However, the  
level of energy emitted is far much less than the electromagnetic energy emitted by wireless devices like  
for example mobile phones.  
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 might be restricted by the proprietor  
of the building or responsible representatives of the organization. These situations and areas might 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 to the use of wireless devices in a specific organization (such as  
airport or 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 UltraConnect™ wireless antenna system built into the

Appendix B. WEEE and recycling statements  
Lenovo encourages owners of information technology equipment to responsibly recycle their equipment  
when it is no longer needed. Lenovo offers a variety of programs and services to assist equipment owners in  
recycling their IT products. Information on product recycling offerings can be found on Lenovo's Internet site  
at http://www.lenovo.com/social_responsibility/us/en/.  
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 collective 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:

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

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:
