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.

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 41).

5.Remove the following components:

a.Hard drive (see Hard drive on page 44)

b.Optical drive (see Optical drive on page 42)

c.Keyboard (see Keyboard on page 54)

d.Switch cover (see Switch cover on page 56)

e.Speaker assembly (see Speaker assembly on page 58)

f.Display assembly (see Display assembly on page 60)

g.Top cover (see Top cover on page 67)

h.System board (see System board on page 79)

Remove the fan/heat assembly (fan/heat sink appearance may vary):

1.Turn the system board upside down with the external monitor port toward you.

2.Loosen the four Phillips PM2.0×10.0 captive screws (1) that secure the fan/heat sink assembly to the system board.

NOTE: Due to the adhesive quality of the thermal material located between the fan/heat sink assembly and system board components, it may be necessary to move the fan/heat sink assembly from side to side to detach the assembly.
