WARNING: Before you begin any of the procedures in this section, read the safety information
that shipped with your computer. For additional best practices information see

airflow. Restricting the airflow impacts your computer’s performance, possibly causing it to
overheat. If your computer is installed in a corner on a desk leave at least 5.1 cm (2 in) clearance
from the back of the computer to the wall to permit the airflow required for proper ventilation.
NOTE: Clean dust off the grill at the back of the computer whenever it is dusty.
