Fujifilm camera won't charge battery
 

My Fujifilm MX2900 camera works ok when connected to charger power
supply, but it won't charge the battery. I've even tried a brand new
battery with no luck
I see some screws that I could loosen to probably dismantle the case,
but I don't know whether I'd see anything significant inside. If I
knew how to charge the Li-ion battery outside the camera on a charger
that I could buy or build, that would be a big help. Can anyone give
some good advice?
