See this post: Bluetooth Keyboard R12  That user had the same issue with Bluetooth and solved it by using the USB dongle instead. I am thinking it might be some kind of issue with the BIOS and Bluetooth on the Aurora R12/R10, since it seems to work properly on the Aurora R11 in Bluetooth mode. It could also be an issue with the Bluetooth module you selected when you purchased the machine, because there's options between the Killer and I believe DELL and INTEL when it comes to wireless options, and they all have their own implementation of Bluetooth, not even being the same versions.
I got my new Aurora R12 last week, not to mention the increased noise compared to my Aurora R11 desktop, but there has been another problem I have never faced before. I'm using Logitech wireless keyboard on this new Aurora R12 computer, when I press the power button, the Alienware logo show up on screen for about 1 second, then it went totally dark screen, the system is running but I can't get to Windows 10 login screen and the keyboard is not responding, so I have to turn off the computer, plug in a wired keyboard, then press the alienware power button, then I can get the system boots up and log into Windows 10 like it should. then I can unplug the wired keyboard and start using my Logitech wireless keyboard with no problem, I have been doing this steps every single day and it was annoying. I have another Aurora R11 desktop which connected to another logitech wireless keyboard and it has never encountered such issue. does anyone have the same issue or anyone have an idea why this happening and a solution is very much appreciated.
Aurora R12, no wired keyboard, no boot
