Frequently asked questions
What do I do if my Chromebook
stops responding?
1. Press and hold the power button until the Chromebook turns off. Then, restart
the Chromebook.
2. If step 1 does not work:
• For models with an emergency reset hole: Insert a straightened paper clip
into the emergency reset hole to cut off power supply temporarily. Then,
restart the Chromebook with ac power connected.
• For models without an emergency reset hole:
– For models with the removable battery, remove the removable battery
and disconnect all power sources. Then, reconnect to ac power and
restart the Chromebook.
– For models with the built-in battery, disconnect all power sources.
Press and hold the power button for about seven seconds. Then,
reconnect to ac power and restart the Chromebook.
What do I do if I spill liquid on the
Chromebook?
1. Carefully unplug the ac power adapter and turn off the Chromebook
immediately. The more quickly you stop the current from passing through the
Chromebook the more likely you will reduce damage from short circuits.
Attention: Although you might lose some data or work by turning off the
Chromebook immediately, leaving the Chromebook on might make your
Chromebook unusable.
2. Do not try to drain out the liquid by turning over the Chromebook. If your
Chromebook has keyboard drainage holes on the bottom, the liquid will be
drained out through the holes.
3. Wait until you are certain that all the liquid is dry before turning on your
Chromebook.
How do I disinfect my
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.

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.
Figure 7. Illustration of proper seating and computer positioning
© Copyright Lenovo 2021 27
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.
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.
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
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.
