How to reset Texas Instruments TI-84 Plus Calculator?

Q: How can I clear the memory of all variables and lists?

A: Unlike a complete reset (see below) this is pretty safe to do, though be careful not to delete any lists or variables that you need to save. To clear all memory in a TI 84 Plus:

  1. Press 2nd MEM (that is the second function of the + key)
  2. Select 2 (Mem Mgmt/Delete)
  3. Select 1 (All)
  4. Scroll through the list and delete anything that isn't important using the DEL button.
  5. To exit, press 2nd QUIT.

Q: How can I completely reset my TI 84 Plus back to the factory default settings?

A: Be careful with this as it will remove any programs that you may have stored in the calculator. With that disclaimer stated, here's how to reset it:

  1. Press 2nd MEM (that is the second function of the + key)
  2. Choose 7 (Reset)
  3. Scroll right so that ALL is selected
  4. Press 1
  5. Press 2 (Reset, and read the warnings).

  • Enter the memory options by selecting "Mem." Press the "2nd" key followed by the "+" key. Select "Reset" from the memory choices. Use the arrow key to select and delete all memory.

  • After choosing to delete all memory, select "Reset." After this reset, your screen should show "Mem Cleared." Once you have reached this screen, press "Enter." If you installed programs or applications, you may need to remove them manually. Once again, enter the "Mem" command.

  • Press "2" to select Memory Management. If you are deleting programs, input that option from the subsequent menu choices. If you need to remove applications, input that choice and press "Enter. Select the application or program from the list displayed. Press "Del" to request the deletion. Choose "Yes" to confirm your choice.

  • Repeat this process to delete remaining programs manually. After completing this, exit the memory menu and press the "Apps" button. Make sure no applications remain. Additionally, press the "Prgm" button, and check that all programs have been removed.
