Safety guidelines
Always observe the following precautions to reduce the risk of injury and
property damage.
Service and upgrades
CAUTION
Do not attempt to service aproduct yourself unless instructed to do so by the
Customer Support Center or your documentation. Only use aservice 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 apower indicator does not
necessarily mean that voltage levels inside aproduct are zero. Before
you remove the covers from aproduct equipped with an ac power
cord, always make sure that the power is turned off and that the
product is unplugged from any power source. For more information on
CRUs, see "Customer Replaceable Units (CRUs)" in Service and
Troubleshooting Guide that came with your computer. 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.
DANGER
Hazardous moving parts. Keep fingers and other body parts away.
Chapter 1. Important safety information 3

CAUTION
Before replacing any CRUs, turn off the computer and wait three to five minutes to
let the computer cool before opening the cover.
Power cords and power adapters
DANGER
Use only the power cords and power adapters supplied by the product
manufacturer. The power cord and power adapter are intended for use with this
product only. They should never be used with any other product.
The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G,
0.75 mm2,or better. For other countries, the suitable types shall be used
accordingly.
Never wrap apower cord around apower 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 asafety hazard.
Always route power cords or any other cables 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 ashort 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.
Always connect power cords and signal cables in the correct order and 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 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.

Extension cords and related devices
DANGER
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.
Plugs and outlets
DANGER
If areceptacle (power outlet) that you intend to use with your computer equipment
appears to be damaged or corroded, do not use the outlet until it is replaced by a
qualified electrician.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer
to obtain areplacement.
Do not share an electrical outlet with other home or commercial appliances that
draw large amounts of electricity; otherwise, unstable voltage might damage your
computer, data, or attached devices.
Some products are equipped with athree-pronged plug. This plug fits only into a
grounded electrical outlet. This is asafety feature. Do not defeat this safety feature
by trying to insert it into anon-grounded outlet. If you cannot insert the plug into
the outlet, contact an electrician for an approved outlet adapter or to replace the
outlet with one that enables this safety feature. Never overload an electrical outlet.
The overall system load should not exceed 80 percent of the branch circuit rating.
Consult an electrician for more information if you have questions about power
loads and branch circuit ratings.
Be sure that the power outlet you are using is properly wired, easily accessible,
and located close to the equipment. Do not fully extend power cords in away that
will stress the cords.

Batteries
DANGER
Personal computers manufactured by Lenovo contain acoin cell battery to provide
power to the system clock. In addition, many mobile products, such as notebook
computers, utilize arechargeable battery pack to provide system power when in
portable mode. Batteries supplied by Lenovo for use with your product have been
tested for compatibility and should only be replaced with approved parts.
Never attempt to open or service any battery. Do not crush, puncture, or incinerate
batteries or short circuit the metal contacts. Do not expose the battery to water or
other liquids. Only recharge the battery pack strictly according to instructions
included in the product documentation.
Battery abuse or mishandling can cause 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 you notice any discharge from your battery or the buildup of
foreign materials on the battery leads, stop using the battery and obtain a
replacement from the battery manufacturer.
Batteries can degrade when they are left unused for long periods of time. For some
rechargeable batteries (particularly Lithium Ion batteries), leaving abattery unused
in adischarged state could increase the risk of abattery short circuit, which could
shorten the life of the battery and can also pose asafety hazard. Do not let
rechargeable Lithium-Ion batteries completely discharge or store these batteries in
adischarged state.
Chapter 1. Important safety information 7
