So I'm done playing and I shut off my pc, the controller starts blinking and never stops. Ever. I have to remove the battery pack if I want it to stop. Is there another way? Any way to get it to stop trying to connect to something after a given time?
I have a solution for you. Is your PC Windows 10? If it is win10, install the Xbox program, with the program installed, click on the central button of the controller, all the menu settings and the controller settings will appear, in the controller settings you can choose to leave the LED off, or you can do this every time you finish playing.
