Power cords and power adapters
DANGER
Use only the power cords and power adapters supplied by the product anufacturer.
The power cords shall be safety approved. For Ger any, it shall be H03VV-F, 3G, 0.75 2, or
better. For other countries, the suitable types shall be used accordingly.
Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in
ways that can cause the cord to fray, crack, or cri p. This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.
Protect power cords and power adapters fro liquids. For instance, do not leave your power cord
or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids
can cause a short circuit, particularly if the power cord or power adapter has been stressed by
isuse. Liquids also can cause gradual corrosion of power cord ter inals and/or the connector
ter inals on a power adapter, which can eventually result in overheating.
Ensure that all power cord connectors are securely and co pletely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of
overheating (such as defor ed plastic) at the ac input pins 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 da aged in any way.
To prevent possible overheating, do not cover the power adapter with clothing or other objects
when the power adapter is plugged into an electrical outlet.
Extension cords and related devices
Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that ou use
are rated to handle the electrical requirements of the product. Never overload these devices. If power strips
are used, the load should not exceed the power strip input rating. Consult an electrician for more information
if ou have questions about power loads, power requirements, and input ratings.

Plugs and outlets
DANGER
If a receptacle (power outlet) that you intend to use with your co puter equip ent appears to be

Do not bend or odify the plug. If the plug is da aged, contact the anufacturer to obtain a
replace ent.
Do not share an electrical outlet with other ho e or co ercial appliances that draw large
a ounts of electricity; otherwise, unstable voltage ight da age your co puter, data, or attached
devices.
So e 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 syste load should not exceed 80 percent of the branch
circuit rating. Consult an electrician for ore infor ation 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 equip ent. Do not fully extend power cords in a way that will stress the cords.
Be sure that the power outlet provides the correct voltage and current for the product you are
installing.
Carefully connect and disconnect the equip ent fro the electrical outlet.

Heat and product ventilation
DANGER
Co puters, ac power adapters, and any accessories can generate heat when turned on and when
batteries are charging. Notebook co puters can generate a significant a ount of heat due to their
co pact size. Always follow these basic precautions:
• When your co puter is turned on or the battery is charging, the base, the pal rest, and so e
other parts ay beco e hot. Avoid keeping your hands, your lap, or any other part of your body
in contact with a hot section of the co puter for any extended length of ti e. When you use the
keyboard, avoid keeping your pal s on the pal rest for a prolonged period of ti e. Your
co puter generates so e heat during nor al operation. The a ount of heat depends on the
a ount of syste activity and the battery charge level. Extended contact with your body, even
through clothing, could cause disco fort or even a skin burn. Periodically take breaks fro using
the keyboard by lifting your hands fro the pal rest; and be careful not to use the keyboard for
any extended length of ti e.
• Do not operate your co puter or charge the battery near fla able aterials or in explosive
environ ents.
• Ventilation slots, fans and/or heat sinks are provided with the product for safety, co fort, and
reliable operation. These features ight inadvertently beco e blocked by placing the product on
