Fan/heat sink assembly NOTE: The fan/heat sink assembly spare part kit includes replacement thermal materials. Description Models with Intel processors: ● UMA graphics and Intel HM76 chipset ● UMA graphics and Intel HM86 chipset ● UMA graphics and an Intel Bay Trail chipset ● Discrete graphics and Intel HM76 chipset Models with AMD processors: ● UMA graphics ● Discrete graphics Spare part number 747241-001 747384-001 747243-001 747242-001 747266-001 747267-001 NOTE: To properly ventilate the computer, allow at least 7.6 cm (3.0 in) of clearance on the left side 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 49), and then remove the following components: ● Service door (see Service door on page 55) ● WLAN module (see WLAN module on page 58) ● Top cover (see Top cover/keyboard on page 61) ● System board (see System board on page 83) NOTE: The following procedure includes images for all available fan and heat sink options. Refer to the image that matches your computer. To remove the fan/heat sink assembly: 1. Position the system board upside down. 2. Disconnect the fan cable (1) from the system board. 3. Loosen the screws on the heat sink (2) that secure the fan/heat sink assembly to the system board. 4. Remove the fan/heat sink assembly (3).
