The rear AC plug adapter may be loose and require a wee bit of 
soldering.  If you have the AC plugged in, if you wiggle the plug, do 
you see/hear sparks ?

bad Battery.  Very bad battery. YOu may not be able to recover it. 
Try continual cycles of charge/drain.
I used fans and LED lights to drain a battery as much as possible, 
but I have yet to be able to restore a duo battery. In the end, I had 
one rebuilt with better cells.

>Any ideas on what to do with it would be greatly appreciated.  Thanks.
