I would suggest to proceed in a logical way:
1st make sure that your ac adaptor will provide the right voltage
(avoid voltages above 7.5V [unloaded] !!!!!!!)
2nd leave the battery out in order to avoid this failure factor
3rd try a deep reset (brain wipe) of your Newt, i.e. press the reset button
while you hold down the power switch until you get a message box on the
screen like "Do you really want to erase everything? YES/NO"
4th check if the Newt works fine then
5th bring the battery back into play - try if it will charge. I strongly
suggest to use a program like BattTrax or the battery monitor of Avis
Backdrop to check the charging current, which should be definitely below 1.5
Amps absolute maximum.
Cheers
