This procedure has not yet been confirmed.

To add a BDC to an X24, you will also have to add the bluetooth hinge covers with the button on the right side, p/n 46l6540 (available from ACS for about $25, incl. ship).  The non-bluetooth X24s have the physical switch and BT LED on the motherboard already.  The button on the hinge cover is just a piece of plastic that reaches down to the m/b and pushes the switch.  You will also have to install an antenna.  I don't know what kind of antenna was included with the original bluetooth models.  However, a laptop Wifi antenna with the u.fl connector may be used (search for laptop antenna on ebay).  Finding a good place to place the antenna may be tricky, since the (special) plastic LCD cover, the bottom chassis, and the keyboard bezel all seem to block radio signals (hence the cutouts on the side of the lid on WiFi models).  Any more hints about original antennas and other supported models would be appreciated!

Firmware

A firmware update is available for this card's Bluetooth controller. Unfortunately, the firmware update can only be applied under Windows 2000 and above. Other operating systems are not supported to allow the firmware update to run.

An unofficial work-around for Linux exists, but this has not been confirmed to work and may potentially brick the Bluetooth controller. The work-around is simple. By using the firmware .dfu file provided by the Windows utility and extracting it with cabextract, the firmware image itself should be able to be flashed by the btdfu tool in Linux.

Linux driver

This card will work with the standard Linux Bluetooth drivers.

This device is implemented as a USB device, you might be able to enable or disable it by using Fn-F5.
