Remove the ribbon cable connecting the daughterboard to the mainboard.

Open the microphone to expose a hidden screw

Remove the screw retaining the front plastic facade.

The microphone will now come out. Take care as it's attached to the daughterboard via a small fragile soldered cable.

With the microphone out, remove the screw retaining the daughterboard.

Gently pry the daughterboard out. Prying from the curved section towards the screw (as the yellow arrow points) worked well for me.

Take care once the daughterboard is free, as it is still connected to the mainboard via soldered wires.
