Safety, Environmental, and Ergonomic Instructions 49
• Do not spill food or liquids on your computer.
• Before you clean your device, disconnect the device from the electrical outlet. Clean your device with a
soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable
substances.
• Ensure that nothing rests on your AC adapter’s power cable and that the cable is not located where it
can be tripped over or stepped on.
• Do not store your computer in a low-airflow environment, such as a carrying case or a closed briefcase,
while the computer is turned on. Restricting airflow can damage the computer or cause a fire.
CAUTION: Handling the cord on this product, or cords associated with accessories sold with this product, will
expose you to lead, a chemical known to the State of California to cause birth defects or other reproductive harm.
Wash your hands after handling the cord.
Power Safety
• To help prevent electric shock, plug the AC adapter and device power cables into properly grounded
power sources. These power cables may be equipped with 3-prong plugs to provide an earth grounding
connection. Do not use adapter plugs or remove the grounding prong from the power cable plug. If you
use a power extension cable, use the appropriate type, 2-prong or 3-prong, to mate with the AC
adapter power cable.
• If you use an extension power cable with your AC adapter, ensure that the total ampere rating of the
products plugged in to the extension power cable does not exceed the ampere rating of the extension
cable.
• Use only the Dell-provided AC adapter approved for use with this device. Use of another AC adapter
may cause a fire or explosion.
• If you are using a multiple-outlet power strip, use caution when plugging the AC adapter’s power cable
into the power strip. Some power strips may allow you to insert the plug incorrectly. Incorrect insertion
of the power plug could result in permanent damage to your device, as well as risk of electric shock
and/or fire. Ensure that the ground prong of the power plug is inserted into the mating ground contact
of the power strip.
• Before you connect the device to an electrical outlet, check the AC adapter voltage rating to ensure
that the required voltage and frequency match the available power source.
• To remove the computer from all power sources, turn the computer off, disconnect the AC adapter
from the electrical outlet, and remove any battery installed in the battery bay or module bay.
• Place the AC adapter in a ventilated area, such as a desk top or on the floor, when you use it to run the
computer or to charge the battery. Do not cover the AC adapter with papers or other items that will
reduce cooling; also, do not use the AC adapter inside a carrying case.
• The AC adapter may become hot during normal operation of your computer. Use care when handling
the adapter during or immediately after operation.
