Dell cannot fix this.  Your mobile needs drivers and is not recognized in windows for file transfer access.

This is not a dell issue.

but atleast you should say how i remove them from other device

tanjib,

Did you try to install a bluetooth printer, cell phone or some oither type of bluetooth adapter?

Right click on the Bluetooth Peripheral Devices, then left click uninstall.

This will remove them from the device manager.

yes it is my bluetooth periperal device

After a long long search and troubleshooting, i just found out that "IT ACTUALLY IS NOT A DELL ISSUE". Speedstep is right in saying that the problem was in my Vodafone branded nokia and its accessories. I tried some other nokia and android phones and bluetooth mouse and they work like a charm with the same drivers in the very same operating system. I guess Vodafone branded nokia doesn't support bluetooth tethering fully. Anyways, the post I started has been replied and amply replied. I am thankful to the dell community for the purposeful help and suggestion. And sorry to all those who suffer the same issue. I'd still suggest using the sequential installation for dell drivers.. P.S. To all those who complain about Dell's support, 'to any average user, the best online and local services I found in my city and some other cities of my country, Dell was the easiest to use and least irritating. They have the most user-friendly support system. Switching to other brands from Dell will be a worse experience, at least in Pakistan I guess'
