Make sure you have the batteries in correctly. They alternate
negative, positive, negative, positive. First time I put them in I got it wrong too.

SOURCE: my TI 89 wont turn on

Hello,
Try to increase the contrast
1. Turn it on
2. press [2nd] and release button
3. Press [UpArrow] and release button
4. Repeat steps 2 and 3 until contrast is adequate.

If that does not work use the link below to 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 should 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.
Hope it helps

SOURCE: 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.

SOURCE: New, barely used 89 drains batteries quickly

Because the games programs are writen badly and are running even when the calculator is off. Battery life will be extended if you get rid of the games.

SOURCE: My Ti 89 won't turn

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.

Tried new batteries TI-89 titanium turns on then immediately off. New batteries didn't help and we checked orientation.


Try taking all the batteries out for 5 minutes, then place them in right order back again. I know it's a simple solution, but i worked for me. I was so worried that my calculator had short circuited, and that i had to invest in a new. Mine works now.

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.

Ti 89 Titanium Battery use


I have a regular TI-89 (HW2)...have had it for 6 or 7 years. Suddenly it's doing the same thing. I have to put new batteries in it every week or so. I even replaced the backup Li-Ion battery. I'm getting really tired of buying new batteries but don't want to go shell out 100+ for a new one.

Anyone have anything on this? I'm having trouble finding much on this...

My TI-89 Dies out fast


If you download games and some third party software can be running all the time draining your batteries. Some of the APPS with Ti 84 will do the same thing. I'd try and find the problem software and delete it.

HELP!!


Well, in most calculators, the action of taking out the backup battery practically clears the whole thing. Memory, everything. I myself have a Ti-89 and have not yet experienced this problem, but I have on an older Ti-82 and removed the backup battery and the whole thing is dead now, or at least nothing happens when I turn it on, even after replacing the batteries again. If you still have the manual, I would check out the troubleshooting. If you don't have it, try to find it online. And if you have done both of these things, try getting hold of technical support through Texas Instruments.
