So whenever I plug in my charger, the light on the side turns red and the charging battery sign pops up, as normal, but as soon as the calculator turns off (which it does automatically after inactivity), the light turns green and it stops charging. I have left it overnight and it's still saying low battery. I have also tried to keep it on by using it a lot so that the red light stays on but that's not working and it goes back to low battery when I unplug it. Resetting isn't working either. I've had this calculator for about 1.5 years and it hasn't had any problems with charging until now.
Please help me, I have an exam in 3 days graphing calculators are expensive so I don't want to buy a new one unless I have no other options.
I don't think the charger itself is the problem, but I could be wrong :/
