Roomba is dead . It does not turn on.

Hi, the roomba started when scheduled and then hit the middle of the living room and stopped. When we came home from work, we saw it in the middle and then tried charging it again. When taking it to the charging station it does not lit up or does anything. It simply stop working. It does not do anything whatsoever. Can you please suggest what i can do to fix it?

One more thing. The battery is brand new.

thanks.
