Thank you for the response. As mentioned earlier, this system was not tested with Windows 8. So the drivers are not available. This seems to be an issue with the driver. You can try to install the Dell Control Point software in compatibility mode and turn on Bluetooth from the application.
If the above steps do not work, you may consider installing Windows 7 back to be able to use the Bluetooth function.
Hope this helps.
I have try the steps u gave.
but I still cant use the bluetooth on my laptop.
