For the record - these older calculators are made to be taken apart, maintenanced and fixed. Unlike modern broken obsolescence machines. I love that people actually have the time to post an answer to a fix that says "I have no idea how to fix - buy a new one."
I have a Canon MP250 and had the same problem with keys sticking. I looked on the back of the machine and there was only 2 screws to take off and even if you removed the screws the back does not come off. So I started looking at the front and the keys - and therein lies the solution.
Each of the keys pops off with a flathead screwdriver when you lift on the left side of each key. I recommend only taking 5 or 6 off at a time. Clean with q-tips and alcohol both on the base of the machine and the actual keys. Spray with canned air to remove any other debris. Then reattach - snap each key back on - they only go on in the correct direction. After you have reattached the keys then test the machine. I had an extra problem with the PLUS + key - it still was sticking after the cleaning. So I stared at the base under the PLUS + key and saw 2 small metal pins that needed to be moved to the left with a flathead before you reattached the key. Once that was on correctly everything worked like brand new.

Make sure that there is nothing sticky in your calculator. It's likely that you got something sticky in there and now the pin that you would push down when you push the key is permently down. So if you can kinda try to make it not stick then your set. If it's a teqnical problem then it's time to buy a new calculator. I just went and bought a ti 84 silver and it's great. Best of luck

I haven't used the calculator in a long time(TI 83 plus) and I put in a new set of batteries. The old ones that were in left some battery acid, but not much. The calculator doesn't want to turn on. It's a...


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.

I'm trying to find the fraction button on my texas instrument ti 83 plus calculator and cannot find it


There is no "fraction" button on the TI-83 plus. You will have to press the divide key (2 buttons below the CLEAR key) and then use the parentheses (immediately to the left of the divide key) to tell the calculator the correct order of operations. For example, "1/3x+9" means ".333333x+9", but "1/(3x)+9" means the "x" goes on the bottom of the fraction.

TI 83 plus calculator has dim screen.


TI calculators have an annoying habit of dimming the screen when the batteries are changed. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.
