Caution: Power (Safety Instructions, continued)
•
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.
•
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
computer, 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.
