My TI 89 calculator took a small, 2 foot, drop to the ground and now it won't turn on. I have tried replacing the AAA batteries but still nothing. Could the button battery be bad or is it something more...

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.

Ti-89 won't turn on -replaced AAA batteries -replaced backup battery -pressed left, right, 2nd, on at once no response

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 at all. 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.

Can't turn on Ti-89 after not using for 5 years

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.

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:

Try a new set of batteries (including the backup battery).
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.
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!!)
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.
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:

Try a new set of batteries (including the backup battery).
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.
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.
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.

Please don't get your hopes up, but perhaps something in the following few suggestions will work:

To reinstall the Calculator's operating system, take a look at the following TI site.

http://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetNumber=12089

I would hunt around on the TI knowledge base to see if there are some more useful suggestions if nothing above works. If I find any more info that could be useful I will post it.

HELP!!

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.

Try a hard reset if you're willing to sacrifice the contents of all RAM.

1. Make sure the batteries are installed correctly.
2. Press and hold the 2nd, Left, and Right keys.
3. Press and release the On key.

Mine would not turn on and I tried all the suggestions above. I took it apart and found that there are springs that come off the battery connections that have a bend in them that touches copper pads on the mainboard. The little bend in them had worn through the copper pad (you could see where) and were not making contact. I just bent them a little so that they touched the copper pad in a different spot and it fixed the problem. My TI-89 is 18 years old and I guess all the years of vibration from giggling around caused this to happen. Glad to have it working again. hope this helps.

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 at all. 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.

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 hold the diamond key, then press the + key repeatedly to see whether the screen darkens.

If this doesn't do it, please reply to this post and we can try other things, though they may cause the loss of the contents of memory.

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.
