Chapter 1. Important safety information
Read this first
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 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.
• 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.
© Copyright Lenovo 2019 1
• 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.
2Lenovo Chromebook S345-14AST User Guide
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 H05VV-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.
Chapter 1.Important safety information 3

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.

6Lenovo Chromebook S345-14AST User Guide
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 the bottom cover of the computer more than one minute. 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).
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.
Chapter 1.Important safety information 7
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.
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.
Plastic bag notice
DANGER
Plastic bags can be dangerous. Keep plastic bags away from babies and children to avoid danger of
suffocation.
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.

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 1. 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 510-760 mm (20-30 inch). 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.

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.

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

service specified for your product and the available service. Scheduling of service will depend upon the time
of your call, parts availability, and other factors.
Types of Warranty Service
1. Customer Replaceable Unit (“CRU”) Service
Under CRU Service, the Service Provider will ship CRUs to you at its cost for installation by you. CRU
information and replacement instructions are shipped with your product and are available from Lenovo at any
time upon request. CRUs that are easily installed by you are called “Self-service CRUs.” “Optional-service
CRUs” are CRUs that may require some technical skill and tools. Installation of Self service CRUs is your
responsibility. You may request that a Service Provider install Optional-service CRUs under one of the other
types of warranty service designated for your product. An optional service offering may be available for
purchase from a Service Provider or Lenovo under which Self-service CRUs would be installed for you. You
may find a list of CRUs and their designation in the publication that was shipped with your product or at
https://www.lenovo.com/CRUs. The requirement to return a defective CRU, if any, will be specified in the
instructions shipped with a replacement CRU. When return is required: 1) return instructions, a prepaid return
shipping label, and a container will be included with the replacement CRU; and 2) you may be charged for

center at its expense.
3. Courier or Depot Service
Under Courier or Depot Service, your product will be repaired or exchanged at a designated service center,
with shipping at the expense of the Service Provider. You are responsible for disconnecting the product and
packing it in a shipping container provided to you to return your product to a designated service center. A
courier will pick up your product and deliver it to the designated service center. The service center will return
the product to you at its expense.
4. Customer Carry-In Service
Under Customer Carry-In Service, your product will be repaired or exchanged after you deliver it to a
designated service center at your risk and expense. After the product has been repaired or exchanged, it will
be made available to you for collection. If you fail to collect the product, the Service Provider may dispose of
the product as it sees fit, with no liability to you.
5. Mail-In Service
Under Mail-In Service, your product will be repaired or exchanged at a designated service center after you
deliver it at your risk and expense. After the product has been repaired or exchanged, it will be returned to
you at Lenovo's risk and expense, unless the Service Provider specifies otherwise.

shipment, the Service Provider may dispose of the product as it sees fit, with no liability to you.

responsible for its installation and verification of its operation. The replacement product becomes your
property in exchange for the failed product, which becomes the property of Lenovo. You must pack the
failed product in the shipping carton in which you received the replacement product and return it to Lenovo.

replacement product was received, you may be responsible for any damage to the failed product occurring
during shipment. You may be charged for the replacement product if Lenovo does not receive the failed
product within thirty (30) days of your receipt of the replacement product.
