Uverse remote stopped working - DirecTV

I left house for an hour and when I returned, the S20 remote was no longer working. Nothing. I tried 4 different sets of batteries, nothing. I unplugged the DVR for a while, nothing. AT&T is sending a new one, but it would be nice id this one would work. Every once in a while, the power putting will flash I think 3 times.

This question, "Uverse remote stopped working," is about DirecTV channels, programming, equipment, and sports.
