Description Spare part number For use only on computer models equipped with an AMD processor 682178-001 For use only on computer models equipped with an Intel processor and a graphics subsystem with 682061-001 discrete memory For use only on computer models equipped with an Intel processor and a graphics subsystem with 682060-001 UMA memory NOTE: To properly ventilate the computer, allow at least 7.6 cm (3 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. Turn off 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 the power from the computer by unplugging the power cord from the computer. 3. Disconnect all external devices from the computer. 4. Remove the battery (see Battery on page 47), and then remove the following components: a. Hard drive (see Hard drive on page 48) b. Optical drive (see Optical drive on page 53) Component replacement procedures 81
