Exhaust air is displaced through the ventilation grill located on the rear edge of the computer. Before removing the fan, 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 keyboard/top cover (see Keyboard/top cover on page 23). 5. Disconnect the battery cable from the system board (see Speakers on page 26). Remove the fan: 1.
