My calculator was dead so I installed new batteries. The batteries were installed correctly. I got it to turn on, but it asked me to install the program card in port 2. I remove the card and install it again. It said the same thing. I have a survey card in port 1, and 256 card in port 2. the code used to get in is @@TDS48. Not sure what more I can do. I reset it and that did not do anything. Thanks for any advice you can give me.

Hi 1945779,

Pressing the green button and, the plus sign is to raise the contrast. Keep doing that process because, if the calculator comes on and, the contrast is to low you'll never know the calculator was ever on. You should also make sure the ports are clean and nothing inside them causing the calculator to short out.

Your only suppose the have all the batteries out for 5 minute but, I had a Ti 85 that I had the batteries out for 20 minutes and, it came on. Leave them out for 5 minutes at the start of this process.

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me that anybody could make the same mistake. The small battery should have a plus sign facing up when it is installed properly. And of course, the calculator will never come on if the batteries aren't in correctly.

Setting up the computer and, calculator for new OS installation.

• Make sure TI Connect software is installed on the PC.
• Connect the TI Connectivity cable to the Ti89 titanium and the computer.
• Do not start the TI Connect software, just have it ready and, on the desktop.
• Download the Ti89 Titanium v3.10 OS to the PC's desktop.

Reset the RAM first. If the calculator still won't turn on goto the next paragraph and, set of instructions. On the Ti89 family, press and hold the [2nd] [Left Arrow] and [Right Arrow] keys. then press and release the [ON] key. This should reinitialize the operating system, in which you should see a progress bar or, "Installation in Progress" displayed on the screen.

Hold down the APPS key and, take one AAA battery out of the calculator. Put the one AAA battery back in while still holding down the APPS key. Release the [APPS] key and, be ready to install the new OS v3.10, ASAP!!! The (older Ti89) may need to press [ALPHA] [9] or, just [9] when the calculator display's, "Press to install..." and, then they need to install the new OS, ASAP!!! You have to do this process in the right sequence because, the calculator will be destroyed if you do not.

You can either drag and, drop the new OS into the TI Connect icon (pictured below), on the desktop.

Or click, Start and open Programs, then open TI Tools, then open TI Connect, then open TI OSDownloader. Then just follow the instructions the software gives you. The best way is to drag and, drop the OS into the TI Connect icon because, you know your installing the latest OS. TI OSDownloader might not give you the latest OS version.

If this procedure doesn't work and, is still under "Warranty", I'd see if I could get a replacement from Texas Instruments. Even if out of "Warranty", I'd would still seek replacement with Texas Instruments.

If you have any question just post a comment and, I'll respond quickly.

hi adamsukienni,

Clean the battery damage up real good. Gently scrape to terminals of corrosion. Back in my day we use to put a little bit of coke cola to clean car battery posts to get a good connection. If you could put a little bit of coke on a Q-tip without getting any inside the calculator that would be good. Just let it soak in for about 30 minutes. And gently scrape the bad areas again clean of the corrosion. You have to clean it up to metal so, that when the battery is in it will be metal to metal connection.

If you can download new OS with another Ti83 Plus or, don't want to install the new OS goto Procedure 1.

Be ready to install the new ti 83 OS v.1.19. So, setup your computer with Ti Connect software and, have the new OS v.1.19 download ready and, in "My Documents \ My TI Data \ Downloads." If you need additional instructions on how to connect the computer to the calculator you can read my instructions at another posting I did. You can go to that posting by clicking, "Connection Instructions," under this paragraph. Just remember the OS was for a Ti 84 Plus and, your's is a Ti 83 Plus so, don't download the OS from the other posting. I'll give you a link below this paragraph to download the correct Ti 83 Plus OS v1.19 for your calculator here at your posting. Just follow the other posting to where I say, "You can also go back and, download the Ti 84 Plus guidebook too, if needed." After that statement the computer and, calculator get connected with the cable and, your not ready for that process, yet! When you come back to this posting and you have downloaded the new OS to the proper folder goto Procedure 1.

Additional computer to calculator connection instructions click, "Connection Instructions."

Ti 83 Plus OS v.1.19 download click, "Ti 83 Plus OS v.1.19". Save this download to "My Documents \ My TI Data \ Downloads".

Procedure 1.
Take all the batteries out for 10 minutes, including the very small one that you have to use a small philips screw driver to get it out. Watch out for the spring under the small battery, it might pop out. Replace all the batteries after 10 minutes with new ones, including buying a new small battery. The small one might cost about $5. I know it is expensive but, this might work.

A battery reset procedure should bring your Ti 83 Plus back to life.

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me that anybody could make the same mistake. And of course, the calculator will never come on if the batteries aren't in correctly.

If your Ti 83 Plus turns on when you put the batteries back in you do not have to re-install the OS. I just think it is better since, your OS might be corrupt.

The process below should reset your calculator.

1). Pressing the [2nd] key followed by pressing and releasing the [Up Arrow] key. This adjust the contrast in case the contrast was to low. Keep repeating if necessary for about 10 seconds and, then go to the next step. If calculator comes on and responds to key functions your done. Once again, if your calculator turns on after this procedure you do not have to re-install the new OS. You can quit these procedures now with a perfectly good calculator.

Please be prepared to re-install the calculator's OS, if you run through this process.

2). Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
"Waiting...Please install calculator software now". Connect to other Ti 83 Plus and, install OS from that calculator. Or, follow the instructions, I gave at the other posting "Connection Instructions" to reinstall the calculator operating system and, connect the computer and, calculator. You can start where, I say, "Link your computer and, Ti 84 Plus (Your's is a Ti 83 Plus) with the proper cable (USB or Black Link). Upon completion your Ti 83 Plus will be ready to use and, the new OS installed.

hi bckyshldn,

Did you remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. In the procedure that I give, you hold [DEL] and, re-insert 1 battery. I'm going to go ahead and, restate my instructions for a ti 83 Plus that won't turn on.

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me anybody could make the same mistake. and of course the calculator will never come on if the batteries aren't in correctly.

The process below should reset your calculator.

Please be prepared to re-install the calculator's OS if you run through this process.

Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.

1. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],
   reinsert the AAA battery and then turn the calculator on. The calculator should display the
   message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. If calculator did not display the message try pressing and releasing the [2nd] key followed by pressing and releasing the up arrow for one second. goto step 2.
   
2. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
   "Waiting...Please install calculator software now". Follow the instructions for the
   TI-83 family or TI-84 Plus family to reinstall the calculator operating system. If the calculator did not turn on connect the calculator to the computer and open Ti Connect. Next, open Device Explorer. Is the calculator asking to be installed? goto step 3.
   
3. Steps to re-installing the operating system:
   

   ~Connect the TI Connectivity cable between the PC and the calculator.
   ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
   ~Follow the on-screen directions to reinstall the calculator's OS. When or, if the calculator install the fresh OS goto step 4.
   
   
   

4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
   
   
   

If the above process did not work. Try re-doing the procedure and, extend the time in step 4 by 5 minutes to 10 minutes before you put all the batteries back in the calculator.

Now just in case this calculator wasn't posted correctly. Here's my instructions for a Ti 83 that won't turn on. This is not the same procedure that the Ti 83 Plus has.

1. Try a new set of AAA batteries.
   
2. Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.

   AAA battery and then turn the calculator on.
   

4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. And of course if the calculator does not turn on, I re-do the procedure and, increase the amount of time by 5 minutes to ten minutes that all the batteries are removed.

If this process did not work for. Try re-doing the process and, extend the time by 5 minutes before you put all the batteries back in the calculator.

Batteries are dead or installed improperly or water got inside.

Take out the AAA batteries and hold the on/off key for thirty seconds. Replace the batteries and it should come on. If it doesn't remove the backup battery and the AAA batteries and hold the on/off key for another 30 seconds. Replace all batteries and turn it on again.

I had mine for 15 years. Are the batteries in correct? Might be broke

I had a very similar problem when trying to install the new OS. The way I got it working was

1. make sure you have fresh batteries in.
2. Find a new computer which you have not used neither TI connect nor the calculator on.
3. Download the OS to this computer from Ti´s webpage
4. Install Ti connect and the calculator on this machine 100 % correct! (check other help files for this)
5. Go into Ti connect, and it should find the calculator now.
6. Use the "device explorer" and then the "OS downloader" directing the downloader to the path where you have already downloaded the OS to the computer.

I hope this helps you out...

Can you plug it directly into a adapter, and will it work?
