environment, such as a closed briefcase, while it is running. Restricting the airflow can damage the computer or cause a fire. 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.
