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.
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.
4. Remove the battery (see Battery on page 54 ).
5. Remove the following components:
a. Hard drive (see Hard drive on page 59 )
b. Optical drive (see Optical drive on page 57 )
