The 14 pin Bluetooth Daughter Cards (BDC) are USB Bluetooth Adapters that are installed in a proprietary BDC socket. The connection probably carries usb, power, led and enable signal. The antenna is printed on the PCB. The location varies by model (within the screen, under the palm rest area, etc.); refer to the Hardware Maintenance Manual for the location of the BDC.

As believed so far, all BDCs can be interchanged, allowing newer Bluetooth adapters to be installed in older ThinkPads.

When Bluetooth is enabled, the Bluetooth-logo LED will light up and executing # lsusb will show an entry mentioning "Broadcom".

On recent ThinkPads the Wireless killswitch disables both WiFi and Bluetooth (verified on a ThinkPad Z60m, Z61t, T60, T61 and X61).
