My UPS on my Directv DVR died so I'm thinking of replacing it, but have one question first. If the power fails and does not come on before the UPS fails does the UPS turn back on again after the power returns. I would hate to be away from home for a few days only to return and find my DVR had missed all its scheduled recordings due to the UPS not coming back on. This thought makes me think I might be better off without one. Thoughts anyone......
