I was trying to attach a wireless adapter and unplugged my Tivo box. I set it down on the floor (carpet) and accidently knocked it over. It fell and when I picked it back up I heard something loose. I took the cover off and noticed that the battery and the cradle that it sits in had come off. I tried to re-attach it but it stays loose. Any recomendation on how to re-attach it so that it will secure?
