I Have a Dell Inspiron 7415 2-in-1 that has the most up-to-date Windows 10 on it as well as all the Dell SupportAssist driver updates and such. Randomly when I re-open my laptop, none of my bluetooth devices work (mouse, keyboard, etc.), and when I go to the settings all the devices say that bluetooth is turned off; there is no toggle to turn it back on; it also doesn't appear in device manager. I have tried many solutions; running the troubleshooter (which only returns that my computer is not capable of Bluetooth, which obviously is not correct), turning off fast startup, uninstalling the driver from device manager (I can see it if I view hidden devices) and reinstalling from Dell's website, and nothing works. However, after I give up and let it sit for a while undisturbed, when I open it again it is magically resolved. This has happened a number of times. Yesterday, I eventually tried shutting down my laptop and turning it back on and it resolved, but I tried the same thing today and it didn't work. I have screenshots of everything but the wifi network I am on currently blocks imgur, so I will comment once I can.
