Appendix A. Important safety information
Safety notices
This information can help you safely use your personal 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.
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.
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, go to 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.
• 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.

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

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 cleaning 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).

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 does 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.

44 IdeaPad Flex 3 Chromebook (11″, 6), IdeaPad 3 Chromebook (14″, 6) User Guide
In accordance with the European Directive 2006/66/EC, batteries and accumulators are labeled to indicate
that they are to be collected separately and recycled at end of life. The label on the battery may also include
a chemical symbol for the metal concerned in the battery (Pb for lead, Hg for mercury, and Cd for cadmium).
Users of batteries and accumulators must not dispose of batteries and accumulators as unsorted municipal
waste, but use the collection framework available to customers for the return, recycling, and treatment of
batteries and accumulators. Customer participation is important to minimize any potential effects of batteries
and accumulators on the environment and human health due to the potential presence of hazardous
substances.
Before placing electrical and electronic equipment (EEE) in the waste collection stream or in waste collection
facilities, the end user of equipment containing batteries and/or accumulators must remove those batteries
and accumulators for separate collection.

Important WEEE information
The WEEE marking on Lenovo products applies to countries with WEEE and e-waste regulations (for
example, the European WEEE Directive, India E-Waste Management Rules). Appliances are labeled in
accordance with local regulations concerning waste electrical and electronic equipment (WEEE). These
regulations determine the framework for the return and recycling of used appliances as applicable within
each geography. This label is applied to various products to indicate that the product is not to be thrown
away, but rather put in the established collection systems for reclaiming these end-of-life products.
Users of electrical and electronic equipment (EEE) with the WEEE marking must not dispose of end of life
EEE as unsorted municipal waste, but use the collection framework available to them for the return, recycle,
and recovery of WEEE and to minimize any potential effects of EEE on the environment and human health
due to the presence of hazardous substances. Lenovo electrical and electronic equipment (EEE) may contain
parts and components, which at end-of-life might qualify as hazardous waste.

Appendix C. Accessibility, ergonomic, and maintenance
information
Accessibility and comfort
Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort.
Arrange your workplace and the equipment you use to suit your individual needs and the kind of work that
you perform. In addition, use healthy work habits to maximize your performance and comfort while using
your computer.
Lenovo is committed to providing the latest information and technology to our customers with disabilities.
Refer to our accessibility information which outlines our efforts in this area.
Ergonomic information
Working in the virtual office might mean adapting to frequent changes in your environment. Following some
simple rules will make things easier and bring you the maximum benefits of your computer. Keeping in mind
such basics as good lighting and proper seating, for example, can help you improve your performance and
achieve greater comfort.
This example shows someone in a conventional setting. Even when not in such a setting, you can follow
many of these tips. Develop good habits, and they will serve you well.
Figure 9. Illustration of proper seating and computer positioning
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
corresponding hotkeys on the keyboard to adjust display brightness.
Head position
Keep your head and neck in a comfortable and neutral (vertical or upright) position.
© Copyright Lenovo 2021 51
Chair
Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to best suit
your desired posture.
Arm and hand position
If available, use chair arm rests or an area on your working surface to provide weight support for your arms.
Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal) position. Type with a soft touch
without pounding the keys.
Leg position
Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
What if you are traveling?
It might not be possible to observe the best ergonomic practices when you are using your computer while on
the move or in a casual setting. Regardless of the setting, try to observe as many of the tips as possible.
Sitting properly and using adequate lighting, for example, will help you maintain desirable levels of comfort
and performance.
Questions about vision?
The visual display screens of Lenovo notebook computers are designed to meet the highest standards and
to provide you with clear, crisp images and large, bright displays that are easy to see, yet easy on the eyes.
Of course, any concentrated and sustained visual activity can be tiring. If you have questions on eye fatigue
or visual discomfort, consult a vision care specialist for advice.
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
52 IdeaPad Flex 3 Chromebook (11″, 6), IdeaPad 3 Chromebook (14″, 6) 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.
