Setting Up Your XPS Desktop
Before Setting Up Your Computer
When positioning your computer, ensure that you allow easy access to a power source,
adequate ventilation, and a level surface to place your computer.
Restricting airflow around your computer may cause it to overheat. To prevent overheating
ensure that you leave at least 10.2 cm (4 inches) at the back of the computer and a minimum
of 5.1 cm (2 inches) on all other sides. You should never place your computer in an enclosed
space, such as a cabinet or a drawer when it is powered on.
