Important safety information  
This information can help you safely use your notebook personal computer. Follow and retain all information  
included with your computer. The information in this document does not alter the terms of your purchase  
agreement or the Lenovo Limited Warranty.  
Customer safety is important. Our products are developed to be safe and effective. However, personal  
computers are electronic devices. Power cords, power adapters, and other features can create potential  
safety risks that can result in physical injury or property damage, especially if misused. To reduce these  
risks, follow the instructions in this document carefully. By carefully following the information contained in  
this document and provided with your product, you can help protect yourself from hazards and create a  
safer computer work environment.  
Conditions that require immediate action  
Products can become damaged due to misuse or neglect. Some product damage is serious enough  
that the product should not be used again until it has been inspected and, if necessary, repaired by  
an authorized servicer.  
As with any electronic device, pay close attention to the product when it is turned on. On very rare  
occasions, you might notice an odor or see a puff of smoke or sparks vent from your product. Or you  
might hear sounds like popping, cracking or hissing. These conditions might merely mean that an  
internal electronic component has failed in a safe and controlled manner. Or, they might indicate  
a potential safety issue. However, do not take risks or attempt to diagnose the situation yourself.  
Contact the Customer Support Center for further guidance. For a list of Service and Support phone  
iv User Guide  
 
   
numbers, go to the following Web site:  
http://consumersupport.lenovo.com/  
Frequently inspect your computer and its components for damage or wear or signs of danger. If you  
have any question about the condition of a component, do not use the product. Contact the Customer  
Support Center or the product manufacturer for instructions on how to inspect the product and  
have it repaired, if necessary.  
In the unlikely event that you notice any of the following conditions, or if you have any safety concerns  
with your product, stop using the product and unplug it from the power source and telecommunication  
lines until you can speak to the Customer Support Center for further guidance.  
• Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are  
cracked, broken, or damaged.  
• Signs of overheating, smoke, sparks, or fire.  
• Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign  
substances on the battery.  
• A cracking, hissing or popping sound, or strong odor that comes from the product.  
• Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord or  
power adapter.  
• The computer product, power cord, or power adapter has been exposed to water.  
• The product has been dropped or damaged in any way.  
• The product does not operate normally when you follow the operating instructions.  
Note: If you notice these conditions with a product (such as an extension cord) that is not manufactured for  
or by Lenovo, stop using that product until you can contact the product manufacturer for further instructions,  
or until you get a suitable replacement.  
Safety guidelines  
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. Only use a Service 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 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 a power cord, always make  
sure that the power is turned off and that the product is unplugged from any power source. If you have  
any questions or concerns, contact the Customer Support Center.  
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 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 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 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 pins 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  
DANGER  
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  
vi User Guide  
 
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  
DANGER  
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  
CAUTION:  
Do not connect or disconnect any external device cables other than USB cable while the computer  
power is on; otherwise, you might damage your computer. To avoid possible damage to attached  
devices, wait at least five seconds after the computer is shut down to disconnect external devices.  
General battery notice  
DANGER  
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.  
© Copyright Lenovo 2011, 2012  
vii  
 
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  
DANGER  
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.  
The battery pack should be stored at room temperature, charged to approximately 30 to 50%  
of capacity. We recommend that battery pack be charged about once per year to prevent  
overdischarge.  
Lithium coin cell battery notice  
DANGER  
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.  
The following statement applies to users in the state of California, U.S.A.

Perchlorate Material - special handling may apply, See  
www.dtsc.ca.gov/hazardouswaste/perchlorate  
Heat and product ventilation  
DANGER  
Computers, ac power 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 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, comfort, 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 power 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 power 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).

DANGER  
Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the following.  
Laser radiation when open. Do not stare into the beam, do not view directly with optical  
instruments, and avoid direct exposure to the beam.  
Liquid crystal display (LCD) notice  
CAUTION:  
For products with mercury-containing fluorescent lamps (for example, non-LED)  
• The fluorescent lamp in the liquid crystal display contains mercury; dispose of according to local,  
state, or federal laws.  
• The LCD is made of glass, and rough handling or dropping the computer can cause the LCD to  
break. If the LCD breaks and the internal fluid gets into your eyes or on your hands, immediately  
wash the affected areas with water for at least 15 minutes; if any symptoms are present after  
washing, get medical care.  
Using headphones or earphones  
If your computer has both a headphone connector and an audio-out connector, always use the headphone  
connector for headphones (also called a headset) or earphones.  
CAUTION:  
Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of  
the equalizer to maximum increases the earphone and headphone output voltage and the sound  
pressure level. Therefore, to protect your hearing, adjust the equalizer to an appropriate level.  
Excessive use of headphones or earphones for a long period of time at high volume can be dangerous if the  
output of the headphone 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, the 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.

a hidden partition by default to store the system image file and OneKey Rescue system program files. This  
default partition is hidden for security reasons and is the reason the available disk drive space is less than it  
claims. The exact available hard disk drive space depends on the file size of the mirror image file (based on  
the size of operating system and preinstalled software).
