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 qualiﬁ ed 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 ﬁ ts 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
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
• 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.
• Do not charge the battery or operate your computer, ac power adapter, or
accessories near ﬂ ammable materials or in explosive environments.
