Dell LATITUDE C510 - Manual (Page 18)

CAUTION: The AC adapter works with electrical outlets worldwide. However, power
connectors and power strips vary among countries. Using an incompatible cable or
improperly connecting the cable to the power strip or electrical outlet may cause fire or
equipment damage.
NOTICE: When you disconnect the AC adapter from the computer, grasp the adapter cable
connector, not the cable itself, and pull firmly but gently to avoid damaging the cable.
Fan
The computer uses an internal fan to create airflow through the vents, which prevents the computer from
overheating.
NOTE: The computer turns on the fans only when the computer gets hot. The fans may make a noise,
which is normal and does not indicate a problem with the fans or the computer.
CAUTION: Do not block, push objects into, or allow dust to accumulate in the air vents.
Doing so can damage the computer or cause a fire.
