Why my charging light is always on? It kills the battery.
Last night after I unplugged my calculator, I found out the charging light was still on and it couldn't be turned off. The light is on all day today, and it really kills the battery, so by the end of today I have to recharge it . I tried to reset and remove the battery, but these methods didn't help. So I wonder what is wrong with my calc, should I get a new one or should i just get a new battery? Is there anyway i can do to save it? Help S.O.S. Thank you!
