Disconnect the optical drive ribbon cable

Use the flat end of a spudger to flip up the ZIF locking flap that secures the optical drive ribbon cable.
Use blunt tweezers to gently pull the optical drive ribbon cable directly out of its motherboard port.
Grip and pull the blue pull tab, not the entire ribbon cable.
