Question about Texas Instruments TI-89 Calculator

TI-89 Stopped working!

In 2006, the batteries on my TI-89 exploded and started leaking. I put it away for a while and used a different calculator. When I got around to putting to batteries in it, it still wouldn't start. I thought maybe the small round battery had died, so i replaced it also and still it wouldn't start. Is it ruined forever?

    My 89 stopped working gradually. As the year went on the more often it would cut off while in use despite the new batteries I put in

My ti-89 is frozen, no matter what keys i press.and although i took off 4 batteries, but when i put batteries back, it is still same, menu screen.


First try the reset code which is pressing Left-Right-Shift and On at the same time. If that doesn't work you can try removing the batteries and putting them back in while holding the (-) and ) buttons.
If those don't work, there is a back-up battery located under a panel just above the four normal batteries underneath the battery cover. Removing this in addition to the four normal batteries should reset your calculator entirely.
If none of these work then there may be a short in the circuits of your calculator which could have been caused by leaking batteries. In this case you can try disassembling the calculator (being careful to remember how it goes back together) and cleaning the circuit board with circuit cleaner.

Hi, My TI 89 calculator just stopped working. I can't turn it on; I changed battery to brand new ones, but still dead. What can I do?


TI calculators have an annoying habit of dimming the screen 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 and hold the + key for a couple of seconds to see whether the screen darkens.

If this doesn't do it, please reply to this post and we can try something else.

My TI-89 Titanium won't turn on!


A hard reset will clear all memory and should give you back control of the calculator.

1. Put the batteries in the calculator.

2. Press and hold left arrow, right arrow, and 2nd keys.

3. Press and release ON.

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.

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 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...

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.

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.

http://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetNumber=12089

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.
