    • Remove the eight 4 mm screws on the back cover using a Phillips #0 screwdriver.

    After unscrewing the 8 screws, they stay on the back cover.

    • Use the pull tab on the battery connector to lift the connector straight up off its socket on the motherboard, disconnecting it.

    Personally, I would remove the battery as the first stage battery should be disconnected before any work is completed.

    • Remove the single 4 mm Phillips screw securing the bottom left corner of the battery.

    • If you are removing an extended capacity battery, remove the Phillips screw securing the bottom right corner of the battery.

    My laptop had 2 screws holding the battery. I am not sure why. It may be useful to check whether yours has 2 as well. Unlike the laptop’s back cover, after unscrewing the screws on the battery, you have to remove the screws.

    • Remove the fan and heatsink from the laptop.

    • Make sure to wipe off the existing thermal paste from the CPU and heatsink with an alcohol-soaked pad and apply a new layer.

    Why do you have to remove the heatsink when it can just be lifted out with the motherboard?
