WARNING: Do not block, push objects into, or allow dust to accumulate in the air vents. Do not store your Dell computer in a low-airflow
environment, such as a closed briefcase, while it is running. Restricting the airflow can damage the computer or cause a fire. The computer
turns on the fan when the computer gets hot. Fan noise is normal and does not indicate a problem with the fan or the computer.

Quick Setup
WARNING: Before you begin any of
the procedures in this section, read the
safety information that shipped with

practices information, see
www.dell.com/regulatory_compliance.
WARNING: The AC adapter works with
