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 might merely mean that
an internal electronic component has failed in a safe and controlled manner. Or, they might indicate a
potential safety issue. 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:
https://pcsupport.lenovo.com/supportphonelist
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.
Appendix A. Important safety information 35
• 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 ensure
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.
Keep fingers and other parts of your body away from hazardous, moving parts. If you suffer an injury, seek
medical care immediately.
Avoid contact with hot components inside the computer. During operation, some components become hot
enough to burn the skin. Before you open the computer cover, turn off the computer, disconnect power, and
wait approximately 10 minutes for the components to cool.
After replacing a CRU, reinstall all protective covers, including the computer cover, before connecting power
and operating the computer. This action is important to help prevent unexpected electrical shock and help
ensure the containment of an unexpected fire that could happen under extremely rare conditions.
36 User Guide
When replacing CRUs, be cautious of sharp edges or corners that might cause injury. If you suffer an injury,
seek medical care immediately.
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.

Glass parts notice
CAUTION:
Some parts of your product may be made of glass. This glass could break if the product is dropped on
a hard surface or receives a substantial impact. If glass breaks, do not touch or attempt to remove it.
Stop using your product until the glass is replaced by trained service personnel.
Static electricity prevention
Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can damage the part. When you unpack an option or CRU, do not
open the static-protective package containing the part until the instructions direct you to install it.
When you handle options or CRUs, or perform any work inside the computer, take the following precautions
to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the
edges. Never touch exposed circuitry.
• Prevent others from touching components.
• When you install a static-sensitive option or CRU, touch the static-protective package containing the part
to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two
seconds. This reduces static electricity in the package and your body.
• When possible, remove the static-sensitive part from the static-protective packaging and install the part
without setting it down. When this is not possible, place the static-protective packaging on a smooth, level
surface and place the part on it.
• Do not place the part on the computer cover or other metal surface.

information
Accessibility information
Lenovo is committed to providing users who have hearing, vision, and mobility limitations with greater
access to information and technology. This section provides information about the ways these users can get
the most out of their computer experience. You also can get the most up-to-date accessibility information
from the following Web site:
https://www.lenovo.com/accessibility
Ergonomic information
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 when using
your computer.
Working in the virtual office might mean adapting to frequent changes in your environment. Adapting to the
surrounding light sources, active seating, and the placement of your computer hardware, 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 510 mm to 760 mm (20 inches to
30 inches). 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 the
brightness control keys to adjust display brightness.
Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.
© Copyright Lenovo 2020 47
Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to
best suit your comfort 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, helps you maintain desirable levels of comfort and
performance. If your work area is not in an office setting, ensure to take special note of employing active
sitting and taking work breaks. Many product solutions are available to help you modify and expand your
computer to best suit your needs. You can find some of these options at https://www.lenovo.com/accessories.
Explore your options for docking solutions and external products that provide the adjustability and features
that you want.
Questions about vision?
The visual display screens of notebook computers are designed to meet the highest standards. These visual
display screens provide you with clear, crisp images and large, bright displays that are easy to see, yet easy
on the eyes. 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.
Basic maintenance tips
• 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 ℃/41 ℉ or above 35 ℃/95 ℉).
• Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.
• 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 notebook computer, hold it by the bottom. Do not pick up or hold your
notebook computer by the display.
• 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
48 User Guide
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 scratch-like 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.
