Hi Vivek, What operating system are you running on that system?   Have you confirmed that bluetooth is enabled in both the operating system and in the system BIOS? Here is our support article for bluetooth and connecting devices.  If you can provide us a bit more information about your system, what happens when you try to connect a bluetooth device, what operating system, the bluetooth card (model and make) that is in it, and the current driver installed we'll see what else we can offer to try to resolve the problem.  Also, to make it easier for me to help troubleshoot the problem please click on my Dell Todd username and send me a private message with the Dell Service Tag of your Vostro 3446.  Please keep any troubleshooting questions or statement here in this thread so others can see what we do to resolve this problem, in case they also have the same issues. Todd
