Chromebook?
1. Squeeze out excess liquid from wipe or disinfecting cloth before using.
Recommended wipes are hydrogen peroxide wipes and alcohol based wipes.
Do not use wipes containing sodium hypochlorite (bleach).
2. Gently wipe the Chromebook thoroughly, being careful to ensure no liquid
drips into the Chromebook. Do not wipe on connector pins.
3. After disinfecting, follow the cleaning procedure from the wipe supplier to
minimize chemical buildup of disinfectant residue.
4. Always allow the Chromebook to completely dry prior to any use.

Appendix A. Important safety information
Safety notices
This information can help you safely use your 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 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 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, 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.
Extended contact with your body, even through clothing, could cause
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 your hands away from the keyboard by lifting your
hands from the palm rest.
© Copyright Lenovo 2020, 2021 19
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.
• Do not wrap the cords around the ac power adapter while in use.
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 storage 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.
20 Lenovo 10e Chromebook Tablet User Guide
Handle your computer gently.
Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy
objects on your computer, display, or external devices.
Carry your computer carefully.
• 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. You might also 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, 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 21
• 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.
Do not touch hot surface of 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.
22 Lenovo 10e Chromebook Tablet 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 45 W ac power adapter only). 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
