    MY calculater doesnt turns on and it has new batteries

  • Matt Hakness Jan 09, 2008

    I was loading a game (pacman) onto my calculator when it all of the sudden it froze up. I tried taking out the batteries and putting them back in but it keeps on bringing up the same frozen screen. It won't even connect to the computer now when I plug it in (USB). I just bought this calculator yesterday, so I can seem to figure out what went wrong. I there a "reset" button I don't know about or should I just take it back?

My Ti 89 won't turn on an I put brand new batteries in


TI calculators have a habit of dimming the screen contrast 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 and press the the + key to darken the screen. If you go too far, use the diamond and - keys to lighten the screen.

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

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.

Hello Haven't turned my ti-89 on for 9 months. When i turn it on it just reads the top line. Any idea's?


sadly toys usually make you take out batteries if you are not 'playing' with them for a long time, perhaps the batteries attacked your calculator - i have not taken batteries out and 6 months might pass and i don't use my ti 84 and i've been lucky - all still works

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.

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 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.
