iv ThinkSmart Core Kit Hardware Maintenance Manual

Chapter 1. I portant safety infor ation
This chapter provides important safety information for your product.
Note: ThinkSmart Core is referred to as “Computer” in this chapter.
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, go to https://www.lenovo.com/warranty/llw_02.
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. If the computer is used in a manner not specified by
the manufacturer, the protection provided by the computer may be impaired.
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.
Conditions that require i ediate action
Products can beco e da aged due to isuse or neglect. So e product da age 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 ight notice an odor or see a puff of s oke or sparks vent fro your
product. You ight also hear sounds like popping, cracking, or hissing. These ight erely ean that
an internal electronic co ponent has failed in a safe and controlled anner. Or, they ight indicate a
potential safety issue. Do not take risks or atte pt to diagnose the situation yourself. Contact the
Custo er Support Center for further guidance. For a list of Service and Support phone nu bers, see
the following Web site:
https://s artsupport.lenovo.co /supportphonelist
Frequently inspect your co puter and its co ponents for da age, wear, or signs of danger. If you
have any question about the condition of a co ponent, do not use the product. Contact the Custo er
Support Center or the product anufacturer 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 fro the power source and
teleco unication lines until you can speak to the Custo er 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.
• 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 0 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.
2ThinkSmart Core Kit Hardware Maintenance Manual

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 anufacturer.
The power cords shall be safety approved. For Ger any, it shall be H03VV-F, 3G, 0.75 2, 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 cri p. 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 fro 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
isuse. Liquids also can cause gradual corrosion of power cord ter inals and/or the connector
ter inals on a power adapter, which can eventually result in overheating.
Ensure that all power cord connectors are securely and co pletely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of
overheating (such as defor ed 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 da aged 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.
Power cord notice

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.
