Fan/heat sink assembly NOTE: The fan/heat sink assembly spare kit includes replacement thermal material. Description For use only with computers equipped with graphics subsystems with discrete memory For use only with computers equipped with graphics subsystems with UMA memory Spare part number 532141-001 532142-001 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 48). 5. Remove the following components: a. Hard drive (see Hard drive on page 57). b. Optical drive (see Optical drive on page 51). c. Switch cover and keyboard (see Switch cover and keyboard on page 63). d. Display assembly (see Display assembly on page 68). e. Top cover (see Top cover on page 80). f. USB board (see USB board on page 85). g. System board (see System board on page 88). Remove the fan/heat sink assembly: NOTE: Steps 1 through 5 apply only to models with discrete subsystem memory on the system board. Steps 6 through 10 apply only to models with UMA subsystem memory on the system board. 1. Turn the system board upside down, with the expansion port 3 and external monitor port toward you. 2. Disconnect the fan cable (1) from the system board. 3. Loosen the three Phillips PM2.5×14.0 spring-loaded, captive screws (2), (3), and (4) that secure the fan/heat sink assembly to the system board. 92 Chapter 4 Removal and replacement procedures
