Safety and warranty guide
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.
Frequently inspect your computer and its components for damage, 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.
