If you are willing to reset it, hold the "CLEAR" button while you take out the batteries and then let go of clear, then put the batteries back in, and if that don't work, reverse the last two steps, and if that don't work, I suggest that you get professional help

Where is the reset button on a TI-84

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

Can't reset

Make sure to replace the "battery backup" too the little lithium ion battery

Try Adjusting contrast:
Hold down "[2nd]" key press up or down arrow repeatedly to lighten or darken contrast.

First attempt reseting:
Step 1: Remove all the batteries
Step 2: Hold "Clear" key down
Step 3: Still holding "Clear" key reinstall batteries
Step 4: Still holding "Clear" key press "On" key until home screen is displayed.

Second shot reseting:
remove all batteries including lithium ion (backup battery), wait 3 hours and reinstall batteries.

Third Shot reseting:
Step 1: Remove a battery
Step 2: Hold down "DEL" key reinstall battery
Step 3: Possible msg pops up saying "Waiting ... Please install software" IGNORE msg and take out battery again
Step 4: Reinstall battery do not hold down "DEL" key

reseting will cause the handheld to loose all of its stored memory.

Hope that helps!

Calculator will not come on

I have the same problem with the calc not responding to removing one batt and reinstalling while holding clear, etc. My fix is to hook up wires to the battery leads and plug the wire into a 120 volt outlet. Watch it light up, but do NOT breath the smoke as it is extremely toxic. ;-) lkw
