After the screw is removed, carefully unplug the set of wires with one of each colored, red, black, yellow, and blue, from the white connector it is secured at.

To unplug it gently pull the white connector from the adapter, possibly in a back and forth motion to free it.

DO NOT pull on the wires, doing so could cause damage to the wires, or for them to become disconnected to the white adapter they are attached to.
