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 requirements. Exhaust air is displaced through the ventilation grill located on the left side of
the computer.
Before removing the fan/heat sink assembly, 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.
