Heat sink assembly NOTE: The heat sink assembly spare part kit includes replacement thermal materials. Description Heat sink for use in models with Intel processors and discrete graphics Heat sink for use in models with Intel processors and UMA graphics Heat sink for use in models with Intel Pentium and Celeron processors and UMA graphics Heat sink for use in models with an Intel Core i3-3217U processor and UMA graphics Heat sink for use in models with an Intel Core i3-3217U processor and discrete graphics Heat sink for use in models with AMD processors and discrete graphics Heat sink for use in models with AMD processors and UMA graphics Spare part number 757602-001 757603-001 766504-001 766503-001 766502-001 766567-001 766568-001 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 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 cover (see Service cover on page 55) ● Keyboard (see Keyboard on page 57) ● Top cover (see Top cover on page 60) ● WLAN module (see WLAN module on page 71) ● USB board (see USB board on page 67 ● Hard drive (see Hard drive on page 68 ● System board (see System board on page 83) To remove the heat sink assembly: 1. Position the system board upside down. 2. Remove the PM2.0×3.0 screws (1) that secure the heat sink assembly to the system board. Component replacement procedures 91
