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:

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 re.

• 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
