I took my TI-89 apart and found that some parts of the copper connections to the batteries eroded away. I tweaked it so that that the batteries were connected to the circuit board and it could turn on.

Will it connect to the computer using device explorer, This way you might be able to see what the calculator is installed with. And it should turn on automatically.

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.

My TI-89 is frozen is there any way of resetting it or anything I can do? It isn't the batteries.


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If that doesn't do it, reset the calculator. Press and hold the lef-arrow, right-arrow, and 2ND keys, then press and release the ON key.

If that doesn't do it, remove one of the four AAA batteries. Press and hold the ) and (-) keys while replacing the battery. Continue to hold the two keys down for at least five seconds before releasing them.

I have a ti 89 Texas Instruments Graphic calculator which is not responding anymore how do I reset it?

If that doesn't do it, this step will clear all RAM. Press and hold the 2ND, left-arrow, and right-arrow, then press the ON key.

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.
