heating
.

To protect your notebook from damage
and to optimize system performance, be
sure to keep all air all vents unobstructed,
clean, and clear of debris. This may
require periodic cleaning, depending upon
the environment in which the system is
used.
Do not operate the notebook in areas
where the air vents can be obstructed,
such as in tight enclosures or on soft
surfaces like a bed or cushion.
