Chapter 1. Important safety information
Batteries
Personal computers manufactured by Lenovo contain a coin cell battery to
provide power to the system clock. Inaddition, many mobile products, such
as notebook computers, utilize a rechargeable battery pack to provide system
power whenin portable mode. Batteries supplied by Lenovo for use with
your producthave beentested for compatibility and should only be replaced
with approved parts.
Never attemptto openor service any battery. Do notcrush, puncture, or
incinerate batteries or shortcircuit the metal contacts. Do notexpose the
battery to water or other liquids. Only recharge the battery pack strictly
according to instructions included in the productdocumentation.
Battery abuse or mishandling cancause the battery to overheat, which can
cause gasses or flame to “vent” from the battery pack or coin cell. If your
battery is damaged, or if younotice any discharge from your battery or the
buildup of foreign materials onthe battery leads, stop using the battery and
obtain a replacement from the battery manufacturer.
Batteries candegrade whenthey are leftunused for long periods of time. For
some rechargeable batteries (particularly Lithium Ionbatteries), leaving a
battery unused in a discharged state could increase the risk of a battery short
circuit, which could shortenthe life of the battery and canalso pose a safety
hazard. Do notletrechargeable Lithium-Ionbatteries completely discharge
or store these batteries in a discharged state.
Rechargeable battery notice
Do notattemptto disassemble or modify the battery pack. Attempting to do
so cancause anexplosion, or liquid leakage from the battery pack. A battery
pack other thanthe one specified by Lenovo, or a disassembled or modified
battery pack is notcovered by the warranty.
If the rechargeable battery pack is incorrectly replaced, there is danger of an
explosion. The battery pack contains a small amount of harmful substances.
To avoid possible injury:
• Replace only with a battery of the type recommended by Lenovo.
• Keep the battery pack away from fire.
• Do notexpose it to water or rain.
• Do notattemptto disassemble it.
• Do notshort-circuit it.

Chapter 2. Use and care Information
Caring for your computer ----------------------------------------------------------------
Though your computer is designed to functionreliably in normal work
environments, youneed to use commonsense in handling it. By following
these important tips, youwill getthe mostuse and enjoyment out of your
computer.
Being careful about where and how you work.
•Donoteator smoke over your keyboard. Particles thatfall into your
keyboard cancause damage.
•Store packing materials safely out of the reach of childrento prevent the
risk of suffocationfrom plastic bags.
• Keep your computer away from magnets, activated cellular phones,
electrical appliances, or speakers (within 13 cm or 5 in).
•Avoid subjecting your computer to extreme temperatures (below 5°C/41°F
or above 35°C/95°F).
•Some appliances, such as certain portable desktop fans or air purifiers, can
produce negative ions. If a computer is close to such anappliance, and is
exposed for anextended time to air containing negative ions, it may
become electrostatically charged. Such a charge may be discharged
through your hands whenyoutouch the keyboard or other parts of the
computer, or through connectors onI/O devices connected to it. Even
though this kind of electrostatic discharge (ESD) is the opposite of a
discharge from your body or clothing to the computer, it poses the same
risk of a computer malfunction.
Your computer is designed and manufactured to minimize any effects of
electrostatic charge. Anelectrostatic charge above a certain limit, however,
canincrease the risk of ESD. Therefore, whenusing the computer close to
anappliance thatcanproduce negative ions, give special attentionto the
following:
- Avoid directly exposing your computer to the air from anappliance that
canproduce negative ions.
- Keep your computer and peripherals as far as possible from such an
appliance.
- Wherever possible, ground your computer to facilitate safe electrostatic
discharge.

Chapter 2. Use and care Information
Notice of static-electricity
Whenyouhandle options or CRUs, or perform any work inside the
computer, take the following precautions to avoid static-electricity
damage:
- Limit your movement. Movement cancause 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.
- Whenyouinstall a static-sensitive optionor CRU, touch the static-
protective package containing the partto a metal expansion-slotcover or
other unpainted metal surface onthe computer for atleasttwo seconds.
This reduces static electricity in the package and your body.
- Whenever possible, remove the static-sensitive partfrom the static-
protective packaging and install the partwithout setting it down. When
this is notpossible, place the static-protective packaging ona smooth,
level surface and place the partonit.
- Do notplace the partonthe computer cover or other metal surface.
Being gentle with your computer
•Avoid placing any objects (including paper) betweenthe display and the
keyboard or under the keyboard.
•Donotdrop, bump, scratch, twist, hit, vibrate, push, or place heavy objects
onyour computer, display, or external devices.
•Avoid turning the display beyond 130°.
