I figure out to my own answer to my IPod Problems.  This happen to me before.

If the IPod or Nano is frozen “No battery power remains. Please connect IPod to Power”.

Answers that I figure out.

Hold down the Menu on the top and the Center button at the same time on your IPod for few seconds until it unfreeze.  It should go back to the menu as usually.

My Ipod was charged up over night.  When I disconnected it.  It was fine with the power on.  I tired to turn it off by pressing the wheel “Play II”, then I suddenly got that frozen “No battery power remains.  Please connect IPod to Power.”  I did.  It still won’t go away.
