Hello: I know there are a million of these posts however, I couldn't find my specific problem. I have an Xbox 360 wireless controller connected to my PC. Normally the light indicating 1 is light. This lasts for about 5 seconds. Then the light for controller 4 lights at the same time and then 2 and 3 and then 1 and 4 and so on (this happens very quickly). During all this time the controller works fine. Except that every once in a while it disconnects (no lights). Pressing the xbox button inmediately connects it again but is very annoying. Any help what might be the issue? Also, it worked fine before. I´ve just stopped using it for a while and when I went to use again, the problem started. Thanks for any help.
