I have a few Notebooks with Wi-Fi and 3 of those with Bluetooth. The Wi-Fi adapter on those 3 also contains the Bluetooth feature, turn Wi-Fi off and Bluetooth is off. I've worked on, and also junked, several Notebooks and the adapter in them had only 2 wires connected to it so would assume both features of the adapter uses only those two wires. The wires feed through from the motherboard alongside the video cable and are fastened on either side of the LCD panel in the housing and across the top, terminating at either side of the camera lens.
