Decided to just get the dongle...Hopefully that fixes my situation. The bluetooth switch does show on my Inspiron laptop though...strange 
I have a Studio XPS 7100 with windows 10 pro. Lately the Bluetooth toggle switch is gone and I cannot find any sign of Bluetooth in my Device Manager? I only see it listed in Services. Is there a driver or download solution for this?
