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 http://consumersupport.lenovo.com.
Frequently inspect your computer and its components for damage or wear
or signs of danger. If you are unsure 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.
