Replacing the fan will require removal of other parts such as the motherboard, keyboard and the shroud surrounding the keyboard in order to gain access to the fan.

    • Locate the top of the keyboard, then insert a spudger into the top most edge of the keyboard where it meets the bezel surrounding it.

    • When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device. The metal spudger is great when you need serious prying power, but a regular black nylon spudger should be used whenever possible.

    These steps should be prior to step 1.

    Step 1. should be after all screws removed from bottom of unit.

    A. Unplug power cable from unit and wall.

    B. Remove battery from battery compartment on bottom of unit.

    C. Turn unit over to expose the bottom of the unit.

    D. Remove all screws from around bottom of unit (12).

    E. Remove all screws from inside the Battery compartment (6 smaller screws).

    Prior to starting, I found it helpful to have four or five small bowls to keep screws in as they are removed and then stack the bowls with the last screws removed are in the top bowl. This helps in knowing what screws go back into what areas.

    • Using the spudger, lift the keyboard from its base to expose the underside components.

    To detach ribbon cable, simply grab cable near socket on motherboard and slowly pull toward the front of the unit. The cable will be reinstalled by sliding cable tip back under the socket.

    • Using a #4 phillips screwdriver, remove all six 2.3mm screws from the plastic shroud.

    • Then, lift off the shroud to reveal the motherboard beneath.

    Because my unit is over 10 years old, several screws on the bottom would not come out.

    Had to pry the shroud up while removing the screw.

    In order to remove the shroud, you will need to disconnect two cables.

    One is near the touchpad and the other is near the screen.

    There are small clear tabs near the sockets. Using a pair of needle nose pliers, gently grab the tabs and slowly pull away from the sockets staying level with the unit.

    Finally, there are two wire sets between the shroud and the motherboard.

    Each set is a black male unit plugged into a white female unit.

    I used a fine tip standard screwdriver and placed it between the black and white unit.

    Then I gently prayed the black unit away from the white unit.

    Be careful not to damage either sockets and the motherboard.

    The shroud should now lift off.

    • The motherboard is now readily accessible to be removed.

    • Using a spudger, gently pry the ports away from their side port containers to easily remove it.

    Prior to lifting the motherboard, there are several screws and wires to undo.

    Will provide specific details at a later time.

    • Lift the motherboard up and flip it on its back.

    • With the motherboard flipped, the fan is almost ready to be removed.

    • Locate the fan and its copper heat pipe running just behind it.

    • Remove the fan from the heat pipe using slight force as it is held to the pipe with an adhesive tape.

    There are two wire sets and two screws to be removed before the fan will come out.

    The black tape around the fan is easy to remove.

    Once the fan is out it can be tested or in my case clean over 10 years of lint that had clogged the blade of the fan and the exit port on the side of the base.
