Important safety information
Note: Read the important safety information first.
Read this first
This information can help you safely use your notebook computer. Follow and retain all information included
with your computer. The information in this document does not alter the terms of your purchase agreement
or the Limited Warranty. For more information, see "Warranty Information" in the Safety and Warranty Guide
that comes with your computer.
Customer safety is important. Our products are developed to be safe and effective. However, personal
computers are electronic devices. Power cords, power adapters, and other features can create potential
safety risks that can result in physical injury or property damage, especially if misused. To reduce these risks,
follow the instructions included with your product, observe all warnings on the product and in the operating
instructions, and review the information included in this document carefully. By carefully following the
information contained in this document and provided with your product, you can help protect yourself from
hazards and create a safer computer work environment.
Note: This information includes references to power adapters and batteries. In addition to notebook
computers, some products (such as speakers and monitors) ship with external power adapters. If you have
such a product, this information applies to your product. In addition, computer products contain a coin-sized
internal battery that provides power to the system clock even when the computer is unplugged, so the
battery safety information applies to all computer products.
Important information about using your computer
Ensure that you 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 the 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.
© Copyright Lenovo 2018 v
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 subject 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:
• Turn it off.
• Put it in sleep mode.
• Put it in hibernation mode.
This helps to prevent damage to the computer, and possible loss of data.
vi L380, L380 Yoga, S2 3rd Gen, and S2 Yoga 3rd Gen User Guide
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, make sure 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.
© Copyright Lenovo 2018 vii
• Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are
cracked, broken, or damaged.
• Signs of overheating, smoke, sparks, or fire.
• Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign
substances on the battery.
• A cracking, hissing, or popping sound, or strong odor that comes from the product.
• Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord, or
power adapter.
• The computer product, power cord, or power adapter has been exposed to water.
• The product has been dropped or damaged in any way.
• The product does not operate normally when you follow the operating instructions.
Note: If you notice these conditions with a product (such as an extension cord) that is not manufactured for
or by Lenovo®, stop using that product until you can contact the product manufacturer for further
instructions, or until you get a suitable replacement.
Service and upgrades
Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or
your documentation. Only use a Service Provider who is approved to repair your particular product.
Note: Some computer parts can be upgraded or replaced by the customer. Upgrades typically are referred
to as options. Replacement parts approved for customer installation are referred to as Customer
Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for
customers to install options or replace CRUs. You must closely follow all instructions when installing or
replacing parts. The Off state of a power indicator does not necessarily mean that voltage levels inside a
product are zero. Before you remove the covers from a product equipped with a power cord, always make
sure that the power is turned off and that the product is unplugged from any power source. 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 you open the computer cover, turn off the computer and wait several minutes until the
computer is cool.

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 H03VV-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.
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 supply statement
DANGER
Never remove the cover on a power supply or any part that has the following label attached.
Hazardous voltage, current, and energy levels are present inside any component that has this label
attached. There are no serviceable parts inside these components. If you suspect a problem with
one of these parts, contact a service technician.

Heat and product ventilation
DANGER
Computers, ac power adapters, and many accessories can generate heat when turned on and when
batteries are charging. Notebook computers can generate a significant amount of heat due to their
compact size. Always follow these basic precautions:
• When your computer is turned on or the battery is charging, the base, the palm rest, and some
other parts may become hot. 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 length of time. When you use the
keyboard, avoid keeping your palms on the palm rest for a prolonged period of time. Your
computer generates some heat during normal operation. The amount of heat depends on the
amount of system activity and the battery charge level. Extended contact with your body, 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).

Liquid crystal display (LCD) notice
CAUTION:
The liquid crystal display (LCD) is made of glass, and rough handling or dropping the computer can
cause the LCD to break. If the LCD breaks and the internal fluid gets into your eyes or on your hands,
immediately wash the affected areas with water for at least 15 minutes; if any symptoms are present
after washing, get medical care.
Note: For products with mercury-containing fluorescent lamps (for example, non-LED), the fluorescent lamp
in the liquid crystal display (LCD) contains mercury; dispose of according to local, state, or federal laws.
Using headphones or earphones
CAUTION:
Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of
the equalizer to maximum increases the earphone and headphone output voltage and the sound
pressure level. Therefore, to protect your hearing, adjust the equalizer to an appropriate level.
Excessive use of headphones or earphones for a long period of time at high volume can be dangerous if the
output of the headphone or earphone connectors do not comply with specifications of EN 50332-2. The
headphone output connector of your computer complies with EN 50332-2 Sub clause 7. This specification
limits the computer’s maximum wide band true RMS output voltage to 150 mV. To help protect against
hearing loss, ensure that the headphones or earphones you use also comply with EN 50332-2 (Clause 7
limits) for a wide band characteristic voltage of 75 mV. Using headphones that do not comply with EN 50332-
2 can be dangerous due to excessive sound pressure levels.
If your Lenovo computer came with headphones or earphones in the package, as a set, the combination of
the headphones or earphones and the computer already complies with the specifications of EN 50332-1. If
different headphones or earphones are used, ensure that they comply with EN 50332-1 (Clause 6.5
Limitation Values). Using headphones that do not comply with EN 50332-1 can be dangerous due to
excessive sound pressure levels.

Using the battery
When you 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 enabling you to
take your work wherever you go. With ThinkPad batteries, you are able to work longer without being tied to
an electrical outlet.
Checking the battery status
Move your pointer to the battery-status icon in the Windows notification area to check the battery status. The
battery-status icon displays the percentage of battery power remaining and how long you can use your
computer before you must charge the battery.
The rate at which you use battery power determines how long you can use the battery of your computer
between charges. Because every computer user has individual habits and needs, it is difficult to predict how
long a battery charge lasts. 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 storage drive
– How bright you make the computer display
– How often you use the wireless feature
Charging the battery
When you find that the remaining battery power is low, charge your battery or replace the battery with a
charged battery.
If an ac outlet is convenient, connect the computer to ac power. The battery is fully charged in about four to
eight hours. If the power adapter shipped with your computer supports the rapid charge function, the battery
is 80% charged in about an hour when the computer is turned off. The actual charging time depends on the
battery size, the physical environment, and whether you are using the computer. You can check the battery
charging status at any time through the battery-status icon in the Windows notification area.
Note: To maximize the life of the battery, the computer does not start recharging the battery if the remaining
power is greater than 95%.
Tips on charging the battery
• Before you charge the battery, ensure that the battery temperature is higher than 10°C (50°F) and lower
than 35 °C (95°F).
• Charge the battery in any of the following conditions:
– The percentage of power remaining is low.
– The battery has not been used for a long time.
Maximizing the battery life
To maximize the life of the battery, do the following:
• Use the battery until the charge is 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.

Cleaning the keyboard: Wipe the keys one by one with a lint-free cloth dampened in mild soap and water. If
you wipe several keys at a time, the cloth might hook onto an adjacent key and possibly damage it. Avoid
spraying cleaner directly onto the keyboard. To remove any crumbs or dust from beneath the keys, you can
use a camera blower with a brush or use cool air from a hair dryer.
Cleaning the computer screen: Scratches, oil, dust, chemicals, and ultraviolet light can affect the
performance of your computer screen. Use a dry, soft lint-free cloth to wipe the screen gently. If you see a
scratchlike mark on your screen, it might be a stain. Wipe or dust the stain gently with a soft, dry cloth. If the
stain remains, moisten a soft, lint-free cloth with water or eyeglass cleaner, but do not apply liquids directly
to your computer screen. Ensure that the computer screen is dry before closing it.

Chapter 5. Security
This chapter provides information about how to protect your computer from unauthorized use.
Using passwords
This topic provides information about how to use the power-on password, supervisor password, and hard
disk password.
Passwords introduction
You can help prevent your computer from unauthorized use by using passwords. After you set a password, a
prompt is displayed on the screen each time you turn on the computer. Enter your password at the prompt.
You cannot use the computer unless you type the correct password.
If you have set a power-on password, a supervisor password, or a hard disk password, it unlocks
automatically when the computer resumes from sleep mode.
Note: If a Windows password has been set, you are prompted to enter it when the computer resumes from
sleep mode.
Power-on password
You can set a power-on password to help protect your computer against unauthorized access.
If you set a power-on password, the password prompt is displayed on the screen whenever you turn on the
computer. You must enter the correct password to start using the computer.
When this icon is displayed, type a power-on password or a supervisor password.
Supervisor password
The supervisor password protects the system information stored in the ThinkPad Setup program. It provides
the following security features:
• If only a supervisor password is set, a password prompt is displayed when you try to start the ThinkPad
Setup program. Unauthorized users cannot change most of the system configuration options in the
ThinkPad Setup program without the password.
• The system administrator can use the supervisor password to access a computer even if the user of that
computer has set a power-on password. The supervisor password overrides the power-on password.
• The system administrator can set the same supervisor password on many ThinkPad notebook computers
to make administration easier.
Hard disk passwords
Setting a hard disk password prevents unauthorized access to the data on the hard disk drive. When a hard
disk password is set, you are prompted to type a valid password each time you try to access the hard disk
drive.
The following two types of hard disk passwords can help protect the information stored on the storage drive:
• User hard disk password
© Copyright Lenovo 2018 49
If a user hard disk password has been set, but no master hard disk password has been, the user must
enter the user hard disk password to access files and applications on the storage drive.
• Master hard disk password
The master hard disk password also requires a user hard disk password. The master hard disk password
is set and used by a system administrator. It enables the administrator to access any storage drive in a
system like a master key. The administrator sets the master password; then assign a user password for
each computer in the network. The user can then change the user password as desired, but the
administrator still can get access by using the master password.
When a master hard disk password is set, only the administrator can remove the user hard disk password.
When this icon is displayed, type a user hard disk password. To type a master hard disk password,
press F1. When the icon changes to , type the master hard disk password. To return to the icon
, press F1 again.
Tips on using the hard disk passwords:
• You can set the minimum length of a hard disk password.
• If you set a hard disk password of over seven characters, the storage drive can be used only with a
computer that can recognize a hard disk password of over seven characters. If you then install the storage
drive in a computer that cannot recognize a hard disk password that contains more than seven
characters, you cannot access the drive.
• Record your password and store it in a safe place. If you forget the user hard disk password, or both user
and master hard disk passwords, Lenovo cannot reset your passwords or recover data from the storage
drive. You must take your computer to a Lenovo reseller or a marketing representative to have the storage
drive replaced. Proof of purchase is required, and a fee will be charged for parts and service.
Notes: The eDrive storage drives or Trusted Computing Group (TCG) Opal-compliant storage drives provide
self-encryption capabilities to secure your data.
• If a TCG Opal-compliant storage drive and a TCG Opal management software program are installed, and
the TCG Opal management software program is activated, the hard disk password is not available.
• If an eDrive storage drive is installed in your computer, and your computer is preinstalled with the
Windows 10 operating system, the hard disk password is not available.
Setting, changing, or removing a password
Before you start, print these instructions.
To set, change, or remove a password, do the following:
1. Restart the computer. When the logo screen is displayed, press F1 to start the ThinkPad Setup program.
2. Select Security âž™ Password by using the directional keys.
3. Depending on the password type, select Power-on Password, Supervisor Password, or Hard disk x
Password.
4. Follow the instructions on the screen to set, change, or remove a password.
You might want to record your password and store it in a safe place. Otherwise, if you forget the password,
you have to take your computer to a Lenovo reseller or a marketing representative to have the password
canceled.

Hard disk security
To protect the computer from unauthorized security attacks, refer to the following tips to enhance security:
• Set a power-on password as well as a hard disk password. For security, a longer password is
recommended.
• The hard disk drive built into your computer can be protected by UEFI BIOS. To provide reliable security,
use the security chip and a security program with the Trusted Platform Module (TPM) management
feature. See “Setting the security chip” on page 51.
• If a Disk Encryption storage drive is installed in your computer, ensure to protect the contents of your
computer from unauthorized access by use of drive encryption software, such as Microsoft Windows
BitLocker® Drive Encryption.
• Before you dispose of, sell, or hand over your computer, delete the data stored on it. For more
information, see “Deleting data from your storage drive” on page 53.
Using Windows BitLocker Drive Encryption
To help protect your computer against unauthorized access, use the drive encryption software, such as
Windows BitLocker Drive Encryption.
Windows BitLocker Drive Encryption (referred to as BitLocker) is an integral security feature of some editions
of the Windows operating system. It can help you protect the operating system and data stored on your
computer, even if your computer is lost or stolen. BitLocker can encrypt all user and system files, including
the swap and hibernation files.
BitLocker uses the TPM to provide enhanced protection for your data and to ensure early boot component
integrity. A compatible TPM is defined as a V2.0 TPM.
To check the BitLocker status, go to Control Panel, view Control Panel by Category, and click System and
Security âž™ BitLocker Drive Encryption.
For more information, see the help system of the Windows operating system, or search for “Microsoft
Windows BitLocker Drive Encryption Step-by-Step Guide” on the Microsoft Web site.
Disk Encryption hard disk drive and Encryption solid-state drive
Some models contain the Disk Encryption hard disk drive, Encryption solid-state drive, or Encryption hybrid
drive. This encryption technology 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, set a hard disk password for the internal storage drive.
Setting the security chip
Strict security requirements are imposed on network client computers that transfer confidential information
electronically. Depending on the options you ordered, your computer might have an embedded security chip
(a cryptographic microprocessor). With the security chip, you can do the following:
• Protect your data and system
• Strengthen access controls
• Secure communications
Before you start, print these instructions.
To set an item on the Security Chip submenu, do the following:
Chapter 5 Security.51
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 stained with dirt, mud, or oil.
• The surface of your finger is different from the one when you enrolled your fingerprint.
• Your finger is wet.
• Your finger that you are currently using has not been enrolled before.
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.
Deleting data from your storage drive
Some of the data stored on the storage drive might be sensitive. Handing your computer over to someone
else without deleting the installed software, such as operating systems and programs, might even violate the
license agreements. Be sure to delete data stored on the storage drive before you dispose of, sell, or hand
over your computer.
You can use the following methods to delete data from the storage drive:
• Move the data to the Recycle Bin, and then empty the Recycle Bin.
• Format your storage drive, using the software to initialize it.
• Use the recovery program provided by Lenovo to bring the storage drive back to the factory default
settings.
These operations, however, only change the file location of the data; they do not delete the data itself. 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 storage drives for unexpected purposes.
To prevent leakage of data, it is important that you delete 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 it is recommended that you use the software (payware) or service (pay service) developed for that
purpose. The process might take several hours.
For disposing of data on the solid-state drive, Lenovo provides the Drive Erase Utility for Resetting the
Cryptographic Key and Erasing the Solid State Drive tool.
Some computers might support a Disk Encryption hard disk drive or Encryption solid-state drive and have
such a drive installed. You can logically dispose of all the data on the drive in a short time by erasing the
cryptographic key. The data encrypted with the old key is not physically erased but remains on the drive;
Chapter 5 Security.53
however, it cannot be decrypted without the old key. This feature is also available with the Drive Erase Utility
for Resetting the Cryptographic Key and Erasing the Solid State Drive tool.
Using firewalls
If your system is preinstalled 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, see the help system that comes with the
program.
Protecting data against 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 your antivirus software, see the help system of your antivirus software.

Installing device drivers
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 component, the operating system must 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 properly if corruption occurs.
It is not always necessary to download the latest drivers. However, you should download the latest driver for
a component when you notice poor performance from that component or when you added a component.
This action might eliminate the driver as the potential cause of a problem.
Getting the latest drivers from the Web site
You can download and install updated device drivers from the Lenovo Support Web site by doing the
following:
1. Go to http://www.lenovo.com/support.
2. Select the entry for your computer and then follow the instructions on the screen to download and install
necessary software.
Getting the latest drivers using Lenovo Companion
The system update function of Lenovo Companion helps you keep the software on your computer up-to-
date. Update packages are stored on Lenovo servers and can be downloaded from the Lenovo Support Web
site. Update packages can contain applications, device drivers, UEFI BIOS flashes, or software updates.
When Lenovo Companion connects to the Lenovo Support Web site, the program automatically recognizes
the following information and determines what updates are available for your computer:
• Machine type and model of your computer
• Installed operating system
• Language of the operating system
Lenovo Companion 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, Lenovo Companion
automatically downloads and installs the updates.
Lenovo Companion 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 the critical severity level so the list you choose from contains only those update types
that you need.
For more information about how to use Lenovo Companion, see the help system of the program.
Using the ThinkPad Setup program
The ThinkPad Setup program enables you to select the preferred settings for your computer through
configuring the BIOS.
