For use only with computer models equipped with Intel processors
NOTE:
To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the right side
and rear panel of the computer. The computer uses an electric fan for ventilation. The fan is controlled
by a temperature sensor and 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.
Before removing the fan, follow these steps:
1.
Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the
computer on, and then shut it down through the operating system.
