Fan Description Fan Spare part number 651897-001 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, 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 50), and then remove the following components: ● Service cover (see WLAN module on page 52) ● Keyboard (see Keyboard on page 61) ● Top cover (see Top cover on page 67) ● System board (see System board on page 74) Remove the fan: 1. Turn the system board upside down, with the rear toward you. 2. Disconnect the fan cable (1) from the system board. 3.
