DELL MX36C ユーザーズマニュアル

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.
