The TI-84 Plus Silver Edition is a graphing calculator released in 2004. It includes a USB port, pre-loaded software, APPS, storage, and a removable front and back case.

Why do the buttons not work?

The calculator is able to be turned on and turns off on its own but I cannot input anything (no numbers, symbols, menus, graphing, etc.). The past uses still show but the cursor just blinks and I am stuck in the screen. I have replaced the batteries to see if that might fix the issue but it still does not work. Thanks!

Refer to this guide for troubleshooting and fixes.

Fun fact: The [on] key is hooked up to the calculator differently from all the other buttons; this is why it works but the others don’t.
