Hi viveksan3,
It appears that the system doesn't have the hardware for the Bluetooth to work. However, you have certain options.
Either you can upgrade the standalone Dell wireless 1502 card with a Bluetooth enabled wireless combo card such as Dell wireless 1701 and Dell wireless 1702 combo cards which are compatible with the system or you can also purchase an external USB Bluetooth adapter. Please refer the image below:
Hope this helps. Please reply for any other questions.
