The computer is equipped with a 3.1-volt, Intel Mobile Pentium II 366-, 333-, 300-, or
266-MHz processor, depending on the model. For ventilation, an electrical fan is
installed. The fan operates on from 5 to 12 volts and is controlled by a temperature
sensor. The fan is designed to turn on automatically when high temperature conditions
exist. These conditions are affected by high external temperatures, system power
consumption, power management/battery conservation configurations, battery fast
charging, and software applications. Exhaust air is displaced through the ventilation
grill located on the left side of the computer.
CAUTION: To properly ventilate the computer, allow at least a 3-inch (7.6 cm) clearance
on the left and right sides of the computer.
