Always observe the following precautions to reduce the risk of injury and
property damage.
Service and upgrades
Do not attempt to service a product yourself unless instructed to do so by the
customer support center or your documentation.
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
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 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 crimp.
This can present a safety hazard.
Always route power cords or any other cables so that they will not be walked
on, tripped over, or pinched by objects.
Note: Some computer parts can be upgraded or replaced by the customer.
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 an AC power cord, always make
sure that the power is turned off and that the product is unplugged from
any power source.

Chapter 1. Important safety information
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 a short 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
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
If a receptacle (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 a replacement.
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 a three-pronged plug. This plug fits only
into a grounded electrical outlet. This is a safety feature. Do not defeat this
safety feature by trying to insert it into a non-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 a way that will stress the cords.
Be sure that the power outlet provides the correct voltage and current for the
product you are installing.
Carefully connect and disconnect the equipment from the electrical outlet.
Power supply statement
Never remove the cover on a power supply or any part that has the
following label attached.
Hazardous voltage, current, and energy levels are present inside any
component that has this label attached. There are no serviceable parts inside
these components. If you suspect a problem with one of these parts, contact a
service technician.
External devices
Do not connect or disconnect any external device cables other than USB and
1394 cables while the computer power is on; otherwise, you might damage
your computer. To avoid possible damage to attached devices, wait at least

Chapter 1. Important safety information
Batteries
Personal computers manufactured by Lenovo contain a coin cell battery to
provide power to the system clock. In addition, many mobile products, such
as notebook computers, utilize a rechargeable 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 a
battery unused in a discharged state could increase the risk of a battery short
circuit, which could shorten the life of the battery and can also pose a safety
hazard. Do not let rechargeable Lithium-Ion batteries completely discharge
or store these batteries in a discharged state.
Rechargeable battery notice
Do not attempt to disassemble or modify the battery pack. Attempting to do
so can cause an explosion, or liquid leakage from the battery pack. A battery
pack other than the one specified by Lenovo, or a disassembled or modified
battery pack is not covered 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 not expose it to water or rain.
• Do not attempt to disassemble it.
• Do not short-circuit it.

• Keep it away from children.
• Do not drop the battery pack.
Do not put the battery pack in trash that is disposed of in landfills. When
disposing of the battery, comply with local ordinances or regulations.
If the battery pack is to be stored separately, place it in a dry environment
of a temperature between 10-35 °C and keep it away from direct sunlight.
To extend battery life, we recommend you charge the battery to
approximately 30 to 50% capacity and recharge it every three months to
prevent the battery from over-discharging.
This system does not support batteries that are not genuine Lenovo-made
or authorized. The system will continue to boot, but may not charge
unauthorized batteries.
Lithium coin cell battery notice
Danger of explosion if battery is incorrectly replaced.
When replacing the lithium coin cell battery, use only the same or an
equivalent type that is recommended by the manufacturer. The battery
contains lithium and can explode if not properly used, handled, or disposed
of.
Do not:
• Throw or immerse into water
• Heat to more than 100°C (212°F)
• Repair or disassemble
Dispose of the battery as required by local ordinances or regulations.
Heat and product ventilation
Computers, AC adapters, and many accessories can generate heat when
turned on and when batteries are charging. Notebook computers can
generate a significant amount of heat due to their compact size. Always
follow these basic precautions:
• When your computer is turned on or the battery is charging, the base, the
palm rest, and some other parts may become hot. Avoid keeping your
hands, your lap, or any other part of your body in contact with a hot
section of the computer for any extended length of time. When you use the

Chapter 1. Important safety information
keyboard, avoid keeping your palms on the palm rest for a prolonged
period of time. Your computer generates some heat during normal
operation. The amount of heat depends on the amount of system activity
and the battery charge level. Extended contact with your body, even
through clothing, could cause discomfort or even a skin burn. Periodically
take breaks from using the keyboard by lifting your hands from the palm
rest; and be careful not to use the keyboard for any extended length of
time.
• Do not operate your computer or charge the battery near flammable
materials or in explosive environments.
• Ventilation slots, fans and/or heat sinks are provided with the product for
safety, c o m fort, and reliable operation. These features might inadvertently
become blocked by placing the product on a bed, sofa, carpet, or other
flexible surface. Never block, cover, or disable these features.
• When the AC adapter is connected to an electrical outlet and your
computer, it generates heat. Do not place the adapter in contact with any
part of your body while using it. Never use the AC adapter to warm your
body. Extended contact with your body, even through clothing, may cause
a skin burn.
For your safety, always follow these basic precautions with your computer:
• Keep the cover closed whenever the computer is plugged in.
• Regularly inspect the outside of the computer for dust accumulation.
• Remove dust from vents and any perforations in the bezel. More frequent
cleanings might be required for computers in dusty or high-traffic areas.
• Do not restrict or block any ventilation openings.
• Do not operate your computer inside furniture, as this might increase the
risk of overheating.
• Airflow temperatures into the computer should not exceed 35°C (95°F).
CD and DVD drive safety
CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or
otherwise physically damaged, it is possible for the disc to break apart or
even shatter when the CD drive is in use. To protect against possible injury
due to this situation, and to reduce the risk of damage to your computer, do
the following:
• Always store CD/DVD discs in their original packaging.

Safety and General Information Guide V1.0_en.book Page 11 Tuesday, August 2, 2011 3:04 PM
12
Chapter 1. Important safety information
Excessive sound pressure from earphones and headphones can cause
hearing loss. Adjustment of the equalizer to maximum increases the
earphones and headphones output voltage and therefore the sound pressure
level.
Excessive use of headphones or earphones for a long period of time at high
volume can be dangerous if the output of the headphones or earphone
connectors do not comply with specifications of EN 50332-2. The headphone
output connector of your computer complies with EN 50332-2 Sub clause 7.
This specification limits the computer's maximum wide band true RMS
output voltage to 150 mV. To help protect against hearing loss, ensure that
the headphones or earphones you use also comply with EN 50332-2 (Clause
7 limits) for a wide band characteristic voltage of 75 mV. Using headphones
that do not comply with EN 50332-2 can be dangerous due to excessive
sound pressure levels.
If your Lenovo computer came with headphones or earphones in the
package, as a set, combination of the headphones or earphones and the
computer already complies with the specifications of EN 50332-1. If different
headphones or earphones are used, ensure that they comply with EN 50332-1
(Clause 6.5 Limitation Values). Using headphones that do not comply with
EN 50332-1 can be dangerous due to excessive sound pressure levels.
Additional safety information
Plastic bags can be dangerous. Keep plastic bags away from babies and
children to avoid danger of suffocation.
(Safety Notice for users in Australia)

Though your computer is designed to function reliably in normal work
environments, you need to use common sense in handling it. By following
these important tips, you will get the most use and enjoyment out of your
computer.
Being careful about where and how you work.
•Do not eat or smoke over your keyboard. Particles that fall into your
keyboard can cause damage.
•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 (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 an appliance, and is
exposed for an extended time to air containing negative ions, it may
become electrostatically charged. Such a charge may be discharged
through your hands when you touch the keyboard or other parts of the
computer, or through connectors on I/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. An electrostatic charge above a certain limit, however,
can increase the risk of ESD. Therefore, when using the computer close to
an appliance that can produce negative ions, give special attention to the
following:
- Avoid directly exposing your computer to the air from an appliance that
can produce 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
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 package 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.
- Whenever possible, remove the static-sensitive part from the static-
protective packaging and install the part without setting it down. When
this is not possible, place the static-protective packaging on a smooth,
level surface and place the part on it.
- Do not place the part on the computer cover or other metal surface.
Being gentle with your computer
•Avoid placing any objects (including paper) between the display and the
keyboard or under the keyboard.
•Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects
on your computer, display, or external devices.
•Avoid turning the display beyond 130°.

Carrying your computer properly
• Before moving your computer, be sure to remove any media, turn off
attached devices, and disconnect cords and cables.
•Be sure your computer is in sleep or hibernation mode, or turned off,
before moving it. This will prevent damage to the hard disk drive and data
loss.
•When picking up your open computer, hold it by the bottom. Do not pick
up or hold your computer by the display.
• Use a quality carrying case that provides adequate cushion and protection.
Do not pack your computer in a tightly packed suitcase or bag.
For outdoor use
• Backup your critical data before you take your computer outdoors.
•Ensure that the battery is full.
•Be sure to turn off the power and close the LCD well.
•When you leave the computer in your car, place it on the back seat to avoid
being insolated.
• Carry the AC adapter and power cord with the computer.
Handling storage media and drives properly
•If your computer comes with an optical drive, do not touch the surface of a
disc or the lens on the tray.
•Wait until you hear the CD or DVD click into the center pivot of an optical
drive before closing the tray.
•When installing your hard disk, follow the instructions shipped with your
hardware, and apply pressure only where needed on the device.

Daughter Card operate within the guidelines found in radio frequency
safety standards and recommendations, Lenovo believes the integrated
wireless cards are safe for use by consumers. These standards and
recommendations reflect the consensus of the scientific community and
result from deliberations of panels and committees of scientists who
continually review and interpret the extensive research literature.
In some situation or environment, the use of wireless LAN PCI Express Mini
Card or Bluetooth Daughter Card may be restricted by the proprietor of the
building or responsible representatives of the organization. These situations
may for example include:
•Using the integrated wireless cards on board of airplanes, or in hospitals
•In any other environment where the risk of interference to other devices or
services is perceived or identified as harmful.
If you are uncertain of the policy that applies on the use of wireless devices
in a specific organization (e.g., airport or hospital), you are encouraged to
ask for authorization to use wireless LAN PCI Express Mini Card or
Bluetooth Daughter Card prior to turning on the computer.

3
Use of mobile devices on board aircraft is explicitly prohibited by many
airlines companies, especially during take-off and landing. The built-in
Mobile Broadband module on your computer is a low-power radio
transceiver. When it is turned on, it intermittently receives and transmits radio
frequency (RF) energy which could cause interference with the operation of
the airplane communication or navigation system. Refer to rules or
regulations of your airline company for Mobile Broadband use. Never enable
Mobile Broadband feature on your computer unless you are explicitly
permitted to do so.
4
Follow restrictions when using your computer in hospitals. Some equipments
in hospitals are sophisticated and are susceptible to electromagnetic
interference. Do not enable Mobile Broadband feature near medical
equipment without requesting permission.
5
The Mobile Broadband communication may affect the operation of implanted
cardiac pacemakers and other medically implanted equipment. Patients with
cardiac pacemakers should be well aware that use of Mobile Broadband
feature on this computer may cause the implanted device to malfunction. If
patients have any doubt that there is interference taking place, immediately
disable the wireless radio on the computer and contact the doctor for more
information.
6
The Mobile Broadband module embedded in your computer does not
support voice calls, hence their use for essential communications is not
possible. Therefore you should never rely upon the device for essential
communications.

Notice on deleting data from your hard disk - - - - - - - - - - - - - - - - - - - - - - - -
As computers spread into every corner of life, they process more and more
information. The data on your computer, some of it sensitive, is stored on a
storage device called the hard disk. Before you dispose of, sell, or hand over
your computer, you need to delete that data.
Handing your computer over to someone else without deleting the loaded
software, such as operating systems and application software, may even
violate License Agreements. You are advised to check the terms and
conditions of those Agreements.
Deleting the data from the hard disk is not easy.
There are methods that seem to delete the data:
•Move the data to the recycle bin, and then choose the Empty recycle bin
command.
•Use the Delete command.
•Format your hard disk, using the software for initializing it.
•Using the preinstalled recovery program, bring the hard disk back to
factory-ship state.
These operations, however, only change the file allocation of the data; they
do not delete the data itself. In other words, the data retrieval processing is
disabled under an operating system such as Windows. The data is still there,
even though it seems to be lost. Thus, it is sometimes possible to read the
data by use of special software for data recovery. There is a risk that people
of bad faith may read and misuse the critical data on hard disks for
unexpected purposes.
To prevent the leakage of data, it becomes very important that you take
responsibility for deleting all the data from the hard disk when you dispose
of, sell, or hand over your computer. You can destroy the data physically by
smashing the hard disk with a hammer, or magnetically by means of strong
magnetic power, thus making the data unreadable. But we recommend that
you make use of the software (payware) or service (pay service) specifically
developed for the purpose.
