Try a hard reset. Be aware that his will clear all RAM. Press and hold the 2nd, left-arrow, and right-arrow keys. Press and release the ON key.

My TI-84 calculator isn't working. When I press the "ON" button, sometimes it would respond, but most of the time it doesn't. The screen just remains blank. I've changed my batteries...


try taking out the triple A batteries and leaving the calculator to sit with them out for a minute or so, replace them and check if it's fixed. If that doesn't work you can do the same, but take out the small button back up battery as well. If you're still not having luck you should call ti cares (800-842-2737) they're usually helpful.

I just changed the batteries and the buttons will do nothing. The menu appears on the screen when the batteries are put in, but I cannot shut it off without removing the batteries. Can I somehow reset...


You can take out the triple a's and leave it sit for a minute or so, if that doesn't work you can do the same thing but take out the small watch battery too. Finally if its still not working you can try calling Ti Cares (800-842-2737), they're usually helpful

When I turn the switch on, ti-89 titanium does not turn on.


If you connect calculator to computer using Ti connect device explorer you might be able to see what files are on the calculator. I don't know if you downloaded from the web but, 3rd party programs and shells tent to miss up the calculator. This would able you to delete out possible problems which could be re installed later.

TI-89. Don't turn on.


I've did the same thing but, with Ti Connect Device Explorer software, I was able to reinstall the OS software. If it is that unresponsive take out all batteries including the backup battery for about 4 hours. I had to do that one time just to get unlocked from the graphing APP. Ti one time told me to miss with the arrow and ESC keys, and it works sometimes. Good Luck, and I hope this helps your posted problem.

TI-89 Won't Turn On


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

For the TI-89 Family, TI-92 Family, and Voyage™ 200:
  1. 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.
  2. 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.
  3. 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.
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.
