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.
