    My TI-85 used up regular AAA batteries too fast, so I switched to Lithium AAA batteries. With these batteries the screen was too dark to see numbers. In searching for a solution to the problem, I came across your website. I tried "2nd, let go, down arrow" several times. This fixed the problem. My calculator is about 14 years old! I love it, cannot be without it.

I have a TI 84 plus silver edition. Won't turn


The problem may be due a screen that is too light to see anything on it. Adjust the screen darkness.
  1. Press [2nd] key and release it.
  2. Press and HOLD the [UpArrow] to draken screen.
  3. Release the [UpArrow] when screen is dark enough.
You can also connect it to the computer to see if TI Connect finds it. If it does, update the OS to version 2.53MP.

You change the backup battery if the calculator tells you RAM CLEARED each time you turn it ON.

TI-89


Did you try [left][right][2nd][on]? It reinitializes the memory and clears the ram.
