How do I fix Error: TI-89 Detected, but could not get status with the TI-89
using the TI Connect software for Windows?
The Operating System (OS) will need to be updated on the TI-89 in order for the TI Connect™ software to detect the status. Try the following procedure to install the OS from the TI-89 Boot Screen. Make sure TI Connect 1.6 is installed on the PC.
• Connect the TI Connectivity cable to the TI-89 and the computer.

• Download the TI-89 v2.09 OS onto the PC's desktop.
**Force TI-89 into "Boot screen" (See instructions below**
• "Press I to install..." ([ALPHA]. [ 9 ]).
• 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 was in my wife's purse, and got soaked in beer (don't ask). After letting it thorougly dry, it powered up no problem (although it still smells like beer). After powering it on, I noticed that the...


as far as the powering down goes, many calculators do that automatically, including the ti-89 series (at least mine does). In regard to the non-functioning keys, I would have to say that the circuit running that particular row of keys was fried in the accident, because the whole block has lost functionality, as opposed to a single key. It may be a prime opportunity to upgrade to a Ti-89 titanium.
hope that helps :)

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.

The only option or keys that will work is the ENTER key and the arrow keys. Try to get your arrow key to work by arrowing down and hit enter hopefully change you to something different.
Next, if at all possible can you hit the MODE key or get into the mode. If you get into the MODE select F3 and then arrow down twice or all the way to the bottom and at APPS Desktop select 1:OFF and then hit the ENTER key. Next, What I really think you need to do is reinstall the Ti 89 OS software. To do so you would need to connect to your computer or another Ti 89 Titanium to your Ti 89 Titanium. If you have Ti connect computer software (from the Ti site) connected to your Ti 89 Titanium it might help you more in troubleshooting any further problems too. You might be able to delete corrupt files that would free your calculator up and start running better.
