Power (Safety Instructions,
continued
)
•
Before you clean your computer, remove power. Clean
your computer with a soft cloth dampened with water.
Do not use liquid or aerosol cleaners, which may
contain flammable substances.
•
Use only the Dell-provided AC adapter approved for
use with this computer. Use of another AC adapter may
cause a fire or explosion.
•
Before you connect the computer 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 power from the computer, turn it off,
remove the battery pack, and disconnect the AC
adapter from the electrical outlet.
•
To help prevent electric shock, plug the AC adapter and
peripheral power cables into properly grounded power
sources. These power cables may be equipped with
three-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, two-
prong or three-prong, to mate with the AC adapter
power cable.
•
Be sure 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.
