Well, in most calculators, the action of taking out the backup battery practically clears the whole thing. Memory, everything. I myself have a Ti-89 and have not yet experienced this problem, but I have on an older Ti-82 and removed the backup battery and the whole thing is dead now, or at least nothing happens when I turn it on, even after replacing the batteries again. If you still have the manual, I would check out the troubleshooting. If you don't have it, try to find it online. And if you have done both of these things, try getting hold of technical support through Texas Instruments.

My ti 83 will turn on when i press the clear thing but when i try to put something in nothing happens


Hi imagenius1,

You need to free up some memory. Try clearing your RAM memory. Your calculator should operate properly afterward.

Press [2nd] [MEM] [7] [1] [2]

If the steps above did not reset the memory to your Ti 83 family calculator try the procedures below.

Please be prepared to re-install the calculator's OS if you run through this process.

If you have a straight Ti 83 without the Plus or, Silver Edition label goto (Procedure 2) below. If your Ti calculator is a Ti 83 Plus or better goto (Procedure 1).


(Procedure 1).

  1. Try a new set of AAA batteries.

  2. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and, then press [CLEAR] one more time to remove the message.

  1. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.



  2. Steps to re-installing the operating system:
    ~Connect the TI Connectivity cable between the PC and the calculator.
    ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
    ~Follow the on-screen directions to reinstall the calculator's OS. If you could not install the new OS on your calculator goto step 4.


  3. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

  4. If the above process did not reset your calculator. Try re-doing (Procedure 1) and, extend the time in step 4, by 5 minutes to 10 minutes before you put all the batteries back in the calculator.

(Procedure 2).


For a straight Ti 83 without the Plus or, Silver Edition label try the procedure below.


  1. Try a new set of AAA batteries.



  2. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the AAA battery and then turn the calculator on.

I put new lithium triple aaa batteries in my TI-83. Nothing happened . days later it turned on worked for a little while then stopped. would it help to change the round lithium battery? Do you know what...


The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).

Do i need both the back up lithium battery and the 4 AAA batteries for my TI-83 calculator to work? Or can it work only with the 4 AAA?


The calculator can work with just the AAA batteries. But, without the backup battery, you'll lose all the contents of memory when the AAAs die. The backup battery is intended to keep the contents refreshed while you replace the AAAs.

Voyage 200 won't turn on


I've fixed my Voyage 200!! I fixed it using the 3rd solution listed below. I've placed them all in there in case the one I used din't work. The funny thing is the solutions listed weren't even for the Voyage 200. I mistakenly tried the wrong one, but it worked!! I've also posted some soultions listed for the Voyage 200 just incase the others don't work and the website I found these solutions can be found here. Good Luck!!

List of solutions that worked for me:

  1. Try a new set of batteries (including the backup battery).
  2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
  3. Remove one of the AAA batteries. Press and hold the CLEAR key. While holding CLEAR, reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the CLEAR key and then press it one more time to remove the message. (worked for me!! Never actually said "Ram Cleared" just had a long box across the screen that filled up and POOF it was back!!)
  4. Remove one of the AAA batteries. Press and hold the DEL key. While holding DEL, reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
  5. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
Voyage Solutions:

For the TI-89 Family, TI-92 Family, and Voyage™ 200:
  1. Try a new set of batteries (including the backup battery).
  2. Adjust the contrast by pressing and releasing the Diamond Key key followed by pressing and releasing the [+] key; repeat as necessary. To adjust or lighten the display, use the [-] key.
  3. Users of the TI-89 Titanium or Voyage 200 should see the following case before performing the following reset procedure to prevent the loss of valuable Apps.
    On the TI-92 family or Voyage 200, hold the [2nd] key and the [hand] key, then press and release the [on] key. On the TI-89 family, press and hold the [2nd] key, left arrow, and right arrow; then press and release the [on] key. This should reinitialize the operating system, in which you should see a progress bar filling on the screen.
  4. Remove one of the AAA or AA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. TI-89, 92 Plus, or Voyage 200 users should see "Press I to install code...", and should press the [9] key. The calculator should then say, "Waiting to receive...". TI-89 Titanium users should see "Waiting to receive..." or "Waiting to received OS...". You will need to restore the calculator's operating system.

Black-Screen/Black-Pixel Fix for TI-Calculator

This will erase all memory and reset defaults.

1. Remove 1 AAA Battery
2. Press and Hold 'ON' for 30 seconds
3. Replace AAA Battery
4. Adjust Contrast to appropriate level

If this fails, try again with ALL Batteries removed including
the backup Lithium Battery.

If all else fails, try the following reset procedure:

1. Remove ALL Batteries (inc. Backup)
2. Let Calculator sit with no batteries for 2~4 hours.
3. Hold 'ON' for 30 seconds.
4. Replace all the batteries (May be good idea to use new batteries
just in case old ones were dead)
5. Turn on Calculator
6. Change Contrast to appropriate level

- Remember to use correct batteries or calculator may not work. The
correct batteries are Alkaline, Rechargable Batteries are TOO WEAK,
Heavy Duty batteries are TOO STRONG.

My TI -89 won`t turn off


Solution that worked for me, taken from "Ti-89 titanium wont turn off":

I was able to fix the problem nut it requires several steps and only offers a temporary fix (untill the calculator is reset then it needs to be done again).
1. Press F5, then Dimond (symbol on buttion) then "Clear"
2. Press "alpha" then "S"
3. Press "0" dont mess with anything else here
4. Press "2nd" then "Quit"
Now you can turn it off but are missing the bottom text (rad,auto, etc...) to fix
6. Press "Mode" change radian to degree then "enter"
Now the text is displayed showing the mode.
7. Set the mode back to radian by reversing step 6.
Thats it I dont know how to get the bottom line back though...
