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, 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.
2.
Disconnect all external devices connected to the computer.
3.
Disconnect the power from the computer by first unplugging the power cord from the AC outlet,
and then unplugging the AC adapter from the computer.
