Plugs And Outlets; Heat And Product Ventilation - Lenovo IdeaPad 65W AC Adapter User Manual

Do not use any power adapter that shows corrosion at the ac input pins
and/or shows signs of overheating (such as deformed plastic) at the ac input
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.

Plugs and outlets

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.
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.
Connect and disconnect the equipment from the electrical outlet carefully

Heat and product ventilation

Computers, ac power adapters, and many accessories can generate heat when
turned on and when batteries are charging. Always follow these basic
precautions:
v Do not leave your computer, ac power adapter, or accessories in contact with
your lap or any part of your body for an extended period when the
products are functioning or when the battery is charging. Your computer, ac
power adapter, and many accessories produce some heat during normal
operation. Extended contact with the body could cause discomfort or,
potentially, a skin burn.
v Do not charge the battery or operate your computer, ac power adapter, or
accessories near flammable materials or in explosive environments.
