TI-89. Don't turn on.

I've tried to update the OS when the battery was low and, in the middle of it, the calculator turned off. It doesn`t turn on again! is there a solution? It`s not the Titanium. Just TI-89.

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.

Hi, i've updated yesterday my nspire cas calculator with the new 3.0 OS and everithing was ok, but today i had turn it on and my nspire crashed in the middle of the load bar with a exclamation triangle...


There is a major bug in the 3.0 OS which does permanently brick TI-Nspire calculators on the 2nd booting of the new OS.

Check here: http://www.omnimaga.org/index.php?topic=7943.0


It's impossible to repair without a special external hardware. You've got to contact TI-Cares and ask for a replacement calculator.

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.

Hello,
The answer I gave you was taken verbatim from the TI FAQ and knowledge base. I copied and pasted the part relevant to you calculator.
In any case, I sent an e-mail message to ti-cares@ti.com, giving the link to your original question and my answer to it. I took the liberty to copy/paste your present message. I also asked about that invalid certificate.
All we can do know is wait for their reply.

My ti-89 won't turn off. when i turn it off it turns back on. any solutions? i have changed the batteries but has not worked.


Hello,

Use the link below to download and install TIConnect software
http://education.ti.com/educationportal/sites/US/productDetail/us_ti_connect.html
Install it on your computer and run it to oppen the main Window. Then connect you calculator to a USB port and, in the TIConnect main window Click the TIConnect TIDeviceInfo. It will try retrieve the info.
If it does your calculator is fine.

If it tells you Device Not found , Click communication settings in same pop up window where it said Not found, and Select Device, Select Cable, Select Port and try OK..

If all that does not work, then it may be time look for a repair shop.

If you are lucky and it works, you reinstall the OS, which can be downloaded from education.ti.com. You drag and drop the OS on the TIconnect main window. Calculator must of couse be connected to computer. Reistalling the OS or updating it will reset machine to factory defaults. That may solve the problem if it is related to the software.
Hope it helps

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
