Sounds like the exact issue I had ...

This is what I did to fix it (you may actually have to re-isntall the driver if it does not appear in device manager after a reboot)

thanks for the tip.  this didn't work for me thouigh.  Went into the Contol Panel / Device Manager but  there is no "Bluetooth Radio" listed

On the "Devices and Printers" I see an Unknown Device that when I select Troubleshoot gives the message "Windows has stopped this device because it has reported problems. (Code 43)"

.

You can try re-insalling the driver. If you go the dell web site and downloads there should be bluetooth driver for your system. Re-install that and then see if it shows up in control pane l / Device Manager and try and trun off the power settings.

thanks again for the suggestion.  I have tried this, as has a Dell support engineer.  The installation runs so far, then prompts me to press a key to activate the wireless. There isn't a key to activate the wireless so at this point my only option is to cancel the install.

after spending a lot of time on the phone with Dell support they have concluded that its a faulty bluetooth card & my solution is to replace it.   the system is under warranty still.

Glad it worked out.

had another call from Dell support last night.  after trying the install of the driver again without success they had me go inside the machine, disconnect and reconnect the bluetooth module from the motherboard.  result is it's now working!
