Fan/heat sink assembly NOTE: All fan/heat sink assembly spare kits include replacement thermal material. Description For use only with computer models using Intel processors: Equipped with discrete video system memory Equipped with UMA video system memory For use only with computer models using AMD processors: Equipped with UMA video system memory Equipped with discrete video system memory Spare part number 448016-001 450934-001 450863-001 450864-001 NOTE: When replacing the fan/heat sink assembly, be sure that the display switch module is removed from the defective fan/heat sink assembly and installed on the replacement fan/heat sink assembly. See Display switch module on page 89 for display switch module removal and spare part number information. 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/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 47). 5. Remove the following components: a. Hard drive (see Hard drive on page 52) b. Optical drive (see Optical drive on page 59) c. Switch cover (see Switch cover on page 61) d. Keyboard (see Keyboard on page 63) e. Speaker assembly (see Speaker assembly on page 66) f. Display assembly (see Display assembly on page 69) g. Top cover (see Top cover on page 75) h.
