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 Lenovo 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 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

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.
• Plugs, power adapters, extension cords, surge protectors, or power supplies that are cracked, broken, or
damaged.
© Copyright Lenovo 2018 vii
• 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 or the power adapter.
• The computer product 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. Before you remove the covers from a product equipped with a power adapter, 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 adapter 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 adapters
DANGER
Use only the power adapters supplied by the product manufacturer.
Never wrap a power adapter cable around a power adapter or other object. Doing so can stress the
cord in ways that can cause the power adapter cable to fray, crack, or crimp. This can present a
safety hazard.
Always route the power adapter cable so that they will not be walked on, tripped over, or pinched by
objects.
Protect power adapters from liquids. For instance, do not leave your 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 adapter has been stressed by misuse. Liquids also can cause gradual
corrosion of the connector terminals on a power adapter, which can eventually result in
overheating.
Ensure that all power adapter 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.
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.
© Copyright Lenovo 2018 ix
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 adapter cable 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).

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.

• Date when your computer was manufactured
• Version of Windows 10 that is preinstalled
Go to
https://www.microsoft.com/en-us/howtotell/Hardware.aspx 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.
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
