Ti-89 Titanium froze

My TI-89 froze while I tried to open a game that a friend of mine transferred to my calculator. Today, I had trouble finding the files, and when I found them I started opening each one to see if they worked. Then I opened one and the screen froze with the busy sign on the right hand lower corner. I pressed the on button, escape button, and off (2nd button then on) button constantly. I also tried removing the batteries. It has been ten minutes now and no response. I also tried looking online for help but so far I haven't found anything and none of my friends have responded with any feedback.

Help please!

    I was running SSII (a game) when it kind of glitched-up and froze. I have tried the same things as you but nothing helps.

SOURCE: TI-89 Titanium (hardcore reset)?

Hi, i was having the same problem.
I wanted to upgrade my Ti 89 titanium OS, so i run the Upgrade check inside the Ti Connect App. It downloaded the OS to a folder. Then i tryed to upgrade with that OS, and in the 99% it fails.
I guess something was wronge since the progress bar in the windows downloader app was out of sync with the calculator percentage. I downloaded myself the OS from Ti, and removed all batteries (including the backup). After plugin in the batteries again, i started the Os downloading with the new file, and the progress was perfectly synced with the calculator percentage.

it finished flawleslly and now it is working :)

please excuse my english, im spanish

Usually you will be able to re-install everything. And I would try uninstalling the program first then if that doen't work just pull the batteries out and put them back in or just press the reset button. Hope this helps. =)

SOURCE: how to change a fraction into a decimal

This is a partial solution for I do not have the TI89 titanium with me.
1. The easiest way is to insert the decimal mark (. dot or , comma) at the end of one of the elements of the fraction (numerator or denominator).

Ex: if you enter 1/2 the calculator displays the fraction 1/2, but if you enter 1./2 or 1/2. or 1./2. it displays 0.5

2. You can also configure the EXACT/APPROXIMATE mode option of the calculator ( Press Mode then scroll till you see exact/approximate) then choose AUTO, EXACT, or APPROXIMATE.

In the EXACT option the calculator will perform exact algebra ( Pi remains Pi not 3.14159... ).
In the APPROXIMATE option, calculations are performed numerically (everything is treated as a decimal number.)

In the AUTO option the calculator will try its best to keep the results as exact as possible :
x/6 + 1/2 yields x/6 + 1/2
x/6. + 1/2 becomes .166666..x +1/2
x/6. + 1./2 becomes .16666..x +0.5

My suggestion ( if you allow me) : Leave the calculator set on AUTO, and convert to decimals as needed by putting the decimal mark at the end of an integer.

I hope it helps.

My TI-89 Titanium's screen froze. Well actually, the cursor kept blinking but none of the buttons worked. I got it to restart using the (-) and ) button trick, but rather than going back to normal it went...


Hi kelsers,

You need to re-install your calculator's OS. After this process your Ti 89 Titanium will operate properly. If you do the process below make sure you use new batteries.

Warning!!! If you do this procedure make sure that your computer and, calculator are connect. Use Ti Connect software and, make sure you can install the OS on the calculator without any interruption. At any time even at the very beginning of this process, if your computer or, calculator gets interrupted or you have a power failure during the installation of the OS, your calculator will be destroyed. So not attempt this procedure during a thunder storm.


You can use the Ti OS Downloader but, you will have no idea what OS is stored by the Ti OS Downloader. So, I suggest following my instructions and, installing the newest Ti 89 Titanium OS 3.10v.

Procedure to installing the newest Ti 89 Titanium OS 3.10v.

You can also get the latest copy of Ti 89 Titanium OS 3.10v by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 89 Titanium OS 3.10v." Once your at the Ti site click the Download Item, Ti 89 Titanium OS 3.10v. Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti 89 Titanium OS 3.10v. will download to you. Click, "SAVE". And then a folder will pop up. It is probably a folder that you download too. If so, you may want to change it and, "Save as" to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 89 Titanium guidebook too, if needed.

Link your computer and calculator with the USB cable or, Direct Black Link cable that came with the calculator.

Remove one of the AAA batteries. Press and hold the [APPS] key, and while holding the [APPS] key, replace the battery and turn the unit on. On the older TI-89 you should see "Press I to install code...", and you should press the [9] key to continue. But, on your Ti 89 titanium it should say, "Waiting to receive..." or, "Waiting to received OS...". Now you need to follow the instructions in the paragraph below to restore the calculator's operating system.

Next, drag the Ti 89 Titanium OS 3.10v. that you copied earlier to "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Next the OS Downloader Warning will pop-up. Click, "OK" to continue and, the new OS will begin to install. The Ti Device window should pop up and, click on to the port where your Ti 89 Titanium is located, USB1 cable or Direct Black COM1. Just click, "Select" and, the OS will continue to download. Upon completion the newest Ti 89 Titanium OS 3.01v. will be installed.

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.
