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, Warranty, and Setup
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.

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 2015, 2017 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 P50 User Guide

Handle your computer gently.

Carry your computer carefully.

Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on
your computer, display, or external devices.

• 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 2015, 2017 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 mm
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.

2

, or

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 50332­2 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.

Labels for the Windows operating systems

Windows 7 Certificate of Authenticity: Computer models preinstalled with the Windows 7 operating

system have a Certificate of Authenticity label affixed to the computer cover or inside the battery
compartment. The Certificate of Authenticity is your indication that the computer is licensed for a Windows 7
product and is preinstalled with a Windows 7 genuine version. In some cases, an earlier Windows version
might be preinstalled under the terms of the Windows 7 Professional license downgrade rights. Printed on
the Certificate of Authenticity is the Windows 7 version for which the computer is licensed and the Product
ID. The Product ID is important in case you need to reinstall the Windows 7 operating system from a source
other than a Lenovo product recovery disc set.

Windows 10 Genuine Microsoft label: Depending on your geographic location, the date when your
computer was manufactured, and the version of Windows 10 that is preinstalled, your computer might have
a Genuine Microsoft label affixed to its cover. See
for illustrations of the various types of Genuine Microsoft labels.

• In the People’s Republic of China, the Genuine Microsoft label is required on all computer models
preinstalled with any version of Windows 10.

• In other countries and regions, the Genuine Microsoft label is required only on computer models licensed
for Windows 10 Pro.

http://www.microsoft.com/en-us/howtotell/Hardware.aspx

The absence of a Genuine Microsoft label does not indicate that the preinstalled Windows version is not
genuine. For details on how to tell whether your preinstalled Windows product is genuine, refer to the
information provided by Microsoft at

Unlike Windows 7 products, there are no external, visual indicators of the Product ID or Windows version for
which the computer is licensed. Instead, the Product ID is recorded in the computer firmware. Whenever a
Windows 10 product is installed, the installation program checks the computer firmware for a valid, matching
Product ID to complete the activation.

In some cases, an earlier Windows version might be preinstalled under the terms of the Windows 10 Pro
license downgrade rights.

Communications Utility

(Windows 7)

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
manually reconfigure your settings and restart the computer each time.

The Active Protection System program protects your internal storage device
(such as 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 internal storage device is less vulnerable to damage when it is not operating.
This is because when the internal storage device 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 on the internal
storage device.

This program enhances your experience with window operation. The window
position of a foreground application is automatically adjusted. The scroll bar on a
user interface is also automatically adjusted.

The Communications Utility program enables you to configure settings for the
integrated camera and audio devices.

Power management

This section provides information about how to use ac power and battery power to achieve the best balance
between performance and power management.

Using the ac power adapter

The power to run your computer can come either from the battery or from ac power. While you use ac power,
the battery charges automatically.

Your computer comes with an ac power adapter and a power cord.

• ac power adapter: Converts ac power for notebook computer use.

• Power cord: Connects the ac outlet and the ac power adapter.

Connecting the ac power adapter

To connect the computer to ac power, ensure that you follow the steps in order:

• Do not bind the power cord tightly around the ac power adapter transformer pack when it is connected to
the transformer.

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

Using the color sensor

Some computer models are equipped with a color sensor. The color sensor enables you to measure and
adjust the color accuracy of your computer display. Therefore, a color image or graphic is rendered as close
as possible to its original intent. The color profile for ThinkPad computer displays is preinstalled on your
computer. If you want to install a different color profile, go to

To use the color sensor, do the following:

• For Windows 7: Open the Start menu, click All Programs ➙ X-Rite ➙ PANTONE Color Calibrator, and
then follow the instructions on the screen.

• For Windows 10: Open the Start menu, click All apps ➙ X-Rite ➙ PANTONE Color Calibrator, and then
follow the instructions on the screen.

When the color sensor is in use, the color-sensor indicator on the computer outer lid blinks twice at regular
intervals. When the color measuring and adjustment finishes, the color-sensor indicator stays on. To locate
the color-sensor indicator, see “Status indicators” on page 7.

Basic maintenance tips

Here are some basic points about keeping your computer functioning properly:

• 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
(more than 13 cm or 5 inches).

• Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F).

• 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. Otherwise, the computer hinge might get damaged.

• Do not turn your computer over when the ac power adapter is plugged in, otherwise, it could break the
adapter plug.

• 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.

• 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.

• Avoid directly exposing your computer and peripherals to the air from an appliance that can produce
negative ions. Wherever possible, ground your computer to facilitate safe electrostatic discharge.

Cleaning your computer

It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free
operation.

Cleaning the computer cover: Wipe it with a lint-free cloth dampened in mild soap and water. Avoid
applying liquids directly to the cover.

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

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:

is displayed, type a power-on password or a supervisor password.

• User hard disk password

© Copyright Lenovo 2015, 2017 57

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.

, 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.

• If a Disk Encryption storage device is installed in your computer, be sure to protect the contents of your
computer memory from unauthorized accesses by use of drive encryption software, such as Microsoft
Windows BitLocker

• Before you dispose of, sell, or hand over your computer, delete data stored on it. For more information,
refer to “Deleting data from your storage drive” on page 63.

The storage device built into your computer can be protected by the UEFI BIOS.

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 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 works by encrypting all user and system files, including the swap
and hibernation files.

®

Drive Encryption.

BitLocker uses a Trusted Platform Module to provide enhanced protection for your data and to ensure early
boot component integrity. A compatible TPM is defined as a V1.2 TPM.

To check the BitLocker status, go to Control Panel, and click System and Security ➙ BitLocker Drive
Encryption.

For more information about Windows BitLocker Drive Encryption, see the help information 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 storage device

Some models contain the Disk Encryption storage device. This feature helps to protect your computer
against security attacks on media, NAND flash, or device controllers by use of a hardware encryption chip.
For the efficient use of the encryption feature, set a hard disk password for the internal storage device.

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:

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;
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.

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

2. Select the entry for your computer and then follow the instructions on the screen to download and install
