    Just pulled my TI-89 out today after a couple of years, frantically replaced the AAA's and the cr-1616 (watch battery) to no avail. Will not turn on. Changing the display brightness/contrast does nothing.

3ft is quite high. Something may be broken. Send it to your retailer for servicing

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.

Ti 89 detected but couldn't get status


Hello,
Here is what the FAQ and Knowledge Base area of the TI site has to say about the problem you are having. Hope it helps.

How do I correct the error message "TI-83 Plus or TI-89 detected, but could not get status" using the TI Connect software for Windows®?

The Operating System (OS) will need to be updated on the TI-83 Plus family or TI-89 calculator in order for the TI Connect software to detect the status. Try the following procedure to install the OS from the TI-83 Plus and TI-89 Boot Screen. Make sure TI Connect 1.6 is installed on the PC.

If using a TI-89 calculator:
• Connect the TI Connectivity cable to the TI-89 calculator and the computer.
• Do not start the TI Connect software.
• Download the TI-89 v2.09 OS onto the PC's desktop.
**Force the TI-89 into the "Boot screen" (see instructions below)**
• "Press I to install..." (press the [9] key).
• Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader.
• Follow the on-screen directions to install OS version 2.09.
The download should begin.
**Steps for Boot Screen:**
• Take one AAA battery out, press and hold down the [APPS] key while reinserting the battery to force device into the Boot Code screen.
• "Press I to install..." will appear.
Once the OS has completed installation, the TI Connect software will be able to detect the TI-89.

My ti-89 will not come on


Check to be sure the battery contacts are actually touching the batteries. You might try bending them in toward the batteries (or stretching the spring a bit (if they are that kind of contact - I can't remember). Also be sure you are using good replacement batteries (sounds silly I know, but sometimes you get a dud).

If it still doesn't come on you might want to try opening it up and looking inside (can't hurt - it's not working anyway, right?). Sometimes, because of a drop, a part might have come loose and can be resoldered or there might be some other visible problem. (My daughter's TI-83 had a little coil that had broken loose after she dropped it, and it was a simple repair.)

Good luck!
