Ti-89 Doesn't Turn OFF!!

I've had my TI-89 Titanium for a few months now and have been using it fairly frequently for Calculus and Physics. However, I've noticed in the past few days that whenever I try turning it off (using 2nd + On), it doesn't turn off. Instead, it turns off for a second and turns right back on. I tried RAM resets and took out regular and backup batteries, all to no avail. Anyone, pleaseee?

Re: Ti-89 Doesn't Turn OFF!!

1) Update the OS from the TI site.
2) check if button is sticking(not necessarily just the plastic button, but what it hits on the inside... you can clean the contacts on the inside of the calc with a Q-tip and rubbing alcohol.)

I don't have much experience with this specific calculator but those are my best bets.

good luck

Ti-89 titanium diagnostics

There is no DiagnosticsOn command in the TI 89 Titanium. The command exists on the TI83/84PLUS where it displays the r and r^2 coefficients. On the TI89 , the correlation coefficient and the determination coefficient (r, r^2) are displayed by default among the statistics if THE REGRESSION MODEL includes them. If they are not defined by the regression model they will not be displayed. In short, you do not have to turn diagnostics ON.

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.

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.

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.
