Air Intake
The fans work with the air intakes to prevent the computer from overheating. When the computer gets hot, the small internal fans turn on and draw air
through the air intakes to cool the computer. Hot air is expelled through the
fan exhausts .
Keyboard Status Lights
NOTICE: To avoid data loss, never turn off the computer while the green light labeled is flashing.
HINT: The computer turns on the fans only when the computer gets hot. They may run most of the time or very seldom, depending on your use of the
computer. Because the fans spin at a high rate of speed, they may make a noise. This noise is normal and does not indicate a problem with the fans or
the computer.
CAUTION: Do not push objects into or block the air intakes. Doing so can cause fire or damage the interior components. Keep the openings free
from dust and other foreign particles.
