Delta Battery

My calculator can not work?

My 84 Silver Edition TI seems to crash. Before that, there is a drain batteries, I do not know if this will an impact on the calculator. Then after that, the buttons (0 1 4 7, Sin App X, T, delta, n) can not work. After a while of trying, buttons can work, but the simulator flashes a few times and it just died off. Changing the battery does not help. Please help me, my exams are around the corner. Thank you!

The leakage of the battery seems to have affected some of the components inside. Buy a new calculator since the repair may not be worth the cost and effort.
