I am trying to use a Bluetooth speaker with my Latitude E5450, running Windows 7. (The speaker connects and plays with my android phone just fine) I have turned on my bluetooth to the computer, I scan for a device. The speaker tower shows up as a headset on the Computer, i add the device. But the device has no information on my computer. under services for bluetooth, it is just blank. I have tried deleting it and reinstalling several times, no change.
