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  
numbers, see the following Web site:  
http://www.lenovo.com/support/phone  
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

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.  
Although there are no moving parts in your computer after the power cord has been disconnected, the  
following warnings are required for your safety.  
CAUTION:  
Hazardous moving parts. Keep fingers and other body parts away.  
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.  
viii User Guide  
 
To prevent possible overheating, do not cover the power adapter with clothing or other objects  
when the power adapter is plugged into an electrical outlet.  
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  
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.

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 cables 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 real-time-clock (RTC) 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 RTC battery. 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 also can  
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.

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.
