I Have a toshiba A200-AH6

Question

i Have a toshiba A200-AH6 PSAE6080c satellite laptop for about 16 months now a week ago my laptop just shut down all of a sudden without any warning.I thought it might be the battery because when i put the laptop back on it shut down before it could successfully boot up into windows it was on AC power when this happens but when i took the battery out and tried it it works great.it only shuts down when the battery is on, i tried a friend of mines battery of the same model and the same thing happened.I think that the charging circuit is damaged but i do not know how to repait it can u help?
