FOLLOW UP on many previous frustrated posts.
Although I had tried multiple drivers from Lenovo, Intel and Microsoft, I have been unable to get my Yoga 2 Pro laptop to load the BT drivers -- no icons, no menu listing, nothing in Device Manager. I fought this for 2 years.
Finally, today I went to the Intel site and downloaded the current Intel Driver Update Utility, installed and ran it. It found two newer drivers for my Yoga 2 Pro. One was a newer PROset wifi driver and the other was a brand new Bluetooth driver dated Aug 22, 2016 (19.0.1621.3340) and my Bluetooth is back. I have no idea why it has taken so long or what disabled it (Microsoft security update is suspected) in the first place but this seems to be working. These are "generic" drivers from Intel but they work.
