Static electricity prevention
Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can damage the part. When you unpack an option or CRU, do not
open the static-protective package containing the part until the instructions direct you to install it.
When you handle options or CRUs, or perform any work inside the computer, take the following precautions
to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the
edges. Never touch exposed circuitry.
• Prevent others from touching components.
• When you install a static-sensitive option or CRU, touch the static-protective packaging containing the
part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two
seconds. This reduces static electricity in the package and your body.
• When possible, remove the static-sensitive part from the static-protective packaging and install the part

With appropriate care and maintenance, your computer will serve you reliably. The following topics offer
information to help you keep your computer working with best performance.
42 Lenovo 100e/300e 2nd Gen User Guide
Basic maintenance tips
Here are some basic points about keeping your computer functioning properly:
• If possible, place your computer in a well-ventilated and dry area without direct exposure to sunshine.
• Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic
bags.
• 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°C/41°F or above 35°C/95°F).
• Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.
• Computer display might be designed to be opened and used at a certain angle. Do not open the display
with force. Otherwise, the computer hinge might get damaged.
• 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 computer, hold it by the bottom. Do not pick up or hold your computer by the
display.
• Only an authorized Lenovo repair technician should disassemble and repair your computer.
• Do not modify or tape the latches to keep the display open or closed.
• 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.
Clean your computer
It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free
operation.
Clean the computer cover: Wipe it with a lint-free cloth dampened in mild soap and water. Avoid applying
liquids directly to the cover.
Clean 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 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.
Clean 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 scratchlike
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.

Appendix B. Accessibility and ergonomic information
This chapter provides information about accessibility and ergonomics.
Accessibility information
Lenovo is committed to providing users who have hearing, vision, and mobility limitations with greater
access to information and technology. You can get the most up-to-date accessibility information from
https://www.lenovo.com/accessibility.

Ergonomic information
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 when using
your computer.
Working in the virtual office might mean adapting to frequent changes in your environment. Adapting to the
surrounding light sources, active seating, and the placement of your computer hardware, 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.
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
brightness control keys to adjust display brightness.
Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.
Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to
best suit your comfort posture.
© Copyright Lenovo 2020, 2021 45
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, helps you maintain desirable levels of comfort and
performance. If your work area is not in an office setting, ensure to take special note of employing active
sitting and taking work breaks. Many product solutions are available to help you modify and expand your
computer to best suit your needs. You can find some of these options at https://www.lenovo.com/accessories.
Explore your options for docking solutions and external products that provide the adjustability and features
that you want.
Questions about vision?
The visual display screens of notebook computers are designed to meet the highest standards. These visual
display screens provide you with clear, crisp images and large, bright displays that are easy to see, yet easy
on the eyes. 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.
