The Inspiron N4010 is not on the list of systems that Dell has tested and confirmed is compatible with W.... So we won't be releasing drivers for that system.
That being said, it doesn't necessarily mean you can't get it to work. That model came with the Dell 365 bluetooth card, and I think that if you go into Device Manager and remove your bluetooth drivers, then reboot the system, Windows 10 may find a native driver that will allow it to work. I believe others have been able to do this and get their bluetooth working.
Try that and let us know if it works for you. If not, we'll see what else we can find to help you out.
Thanks for the reply sir. I have found lenovo driver is working fine for this model of dell. i have installed lenovo driver from one of the post and now it is working fine for my dell laptop, but sometimes after restart of the system it takes time to connect to bluetooth device so i m struggling in this part but its okay now that atleast device is working with some minor problem.
