I have problem with a wireless xbox 360 controller. the problem is, after a little while (the time seems to get shorter and shorter), this controller turns off. First, the light indicating which player it is starts spinning. It;'s like when you introduce a controller to the console, but the spinning is slower. then, it simply turns off, and the 360 gives me a message telling me to reconnect the controller. Like I said, It happens really often. ONce the controller is off, it is impossible to turn back on again. the light simply flashes, but the controller does not stay on. To reconnect the controller, the batteries must be taken out and put back in. Replacing them does not help.
