The DocKtor is often asked, “Can Microsoft Windows BitLocker can be used with Targus Universal Docking Stations?” The answer is, “Yes!”
The only caveat is that you must unlock the drive before the docking station can be used; this is not unlike many security programs that require the user to logon/login before Windows starts up. This is because the DisplayLink software will not be running until Windows is started. Therefore, you should have your local screen active (lid open) to unlock your BitLocker drive and startup Windows.
