Pc Dell Vostro 1710 batterie branchée, pas en charge

Hello,

I own a Pc Dell Vostro 1710

For a while my battery does not work, I do not remember going on my pc if I do not bring food, I tried many things but nothing (remove the battery and put it back with the food, F2 at startup, leave recharge overnight pc turn off, change power cable, battery let stand some time ..)

If anyone knows what I might do that would walk ?? because it starts to ennuier me, what good have a cell if it is to leave the sector: /  www.laptopsbatterie.com/dell-vostro-1710.html

If the battery Dell Vostro 1710 would be "<ADMIN NOTE: Profanity removed as per TOU>" the pc normally we say, right ??

thanks for your answers
