I just went to charge my N810 and instead of seeing the charging screen, it said "Not Charging." I have only had this battery for a about a month and it is a new OEM battery. The battery charged just fine last night and I only used the tablet for a little bit today and when I went to use it, I found that it was dead. Confused, I thought I might have had left the wi-fi on with it on a heavy flash page or something. Anyways, I go to plug it into the charger and it displayed that screen. The only thing I can think of is that I recently got one of those usb to 2.5mm chargers.

Is this a case of premature death of the battery? Or is there anything I can do to revive it?

Thanks
