If you have a play and charge kit you can get around the syncing process by connecting the cable, then pressing the Xbox button on the controller. It will turn the console on and sync with the system. That's what I do when my controller stops working with my console.
Same problem with my wireless controller. It was working fine before, but a couple of days ago when I was playing, the Xbox flashed the message ''Please reconnect controller''. I thought the batteries were dead. I switched the battery pack with a fully charged one. I turned on the controller, but it did not connect, so I turned off my console. I managed to turn it on by pressing the Xbox guide button on the controller, the console recognized the controller but did not connect it to one of the quadrants. I did that reconnecting thing in the booklet that came with the controller, and nothing. I have tried reconnecting the controller many times, and I made sure the console was not near any metallic objects or cordless phones like the booklet told me to. I tried to contact Xbox, but they told me the same thing found in the booklet. I don't know what to do now.
