Well i suggest calling Texas Instruments
The chances of this happening are rare, but the back up
battery probably died. This could probably cause data loss
and you might lose the program and function data. Call and ask
to see what you could do.

My TI-83 Plus Calculator will not power up despite the fact that I have put in new batteries.


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 release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

There's something wrong with my TI-83. When I'm typing up an equation it will randomly shut off. And when it's on it will have shown that the RAM was cleared. Now it sometimes takes like 5 presses of the...


Have you tried changing the batteries? I'd try that first thing. From your description, the problem sounds like you have low batteries. The RAM shouldn't clear itself when you turn the calculator on unless you tried to turn it on when the calculator didn't have any juice. The TI-83 has four AAA batteries and one CR1616 battery it uses for memory backup. The CR1616 isn't enough to power the calculator, just enough to keep your calculator from losing its RAM contents while the primary batteries are out. If you try to power the calculator on without primary batteries, the backup fails. However, the TI-8x line is usually pretty good about warning you when the batteries are low by displaying a big warning message when you turn it on about the batteries being low and a recommended change of batteries. It might not, though, so you really can't be sure until you try a fresh set of batteries. Good luck!

If I have to replace the batteries in my TI-83 Plus calculator, will the programs that I already have in place be lost?


That's what the backup battery is for. It will keep the memory long enough for you to change the AAA batteries. Just don't remove the main and backup batteries at the same time.

My ti 83 will turn on when i press the clear thing but when i try to put something in nothing happens


Hi imagenius1,

You need to free up some memory. Try clearing your RAM memory. Your calculator should operate properly afterward.

Press [2nd] [MEM] [7] [1] [2]

If the steps above did not reset the memory to your Ti 83 family calculator try the procedures below.

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

If you have a straight Ti 83 without the Plus or, Silver Edition label goto (Procedure 2) below. If your Ti calculator is a Ti 83 Plus or better goto (Procedure 1).


(Procedure 1).

  1. Try a new set of AAA batteries.

  2. 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 [CLEAR] one more time to remove the message.

  1. 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.



  2. 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. If you could not install the new OS on your calculator goto step 4.


  3. 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.

  4. If the above process did not reset your calculator. Try re-doing (Procedure 1) and, extend the time in step 4, by 5 minutes to 10 minutes before you put all the batteries back in the calculator.

(Procedure 2).


For a straight Ti 83 without the Plus or, Silver Edition label try the procedure below.


  1. Try a new set of AAA batteries.



  2. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the AAA battery and then turn the calculator on.

If this doesn't do it, please reply to this post and we can take it from there.

TI-83 Plus ram cleared message when turned on


It calculator tells you Ram Cleared each time you turn it on, the most likely reason is that the backup battery is depleted. Its role is to keep the memory modules electrically refreshed when calculator is turned off. If the backup battery is dead, the memory is erased when you turn calculator OFF. Main batteries no longer supply power and the contents of the memory are cleared.
  1. Check that main batteries are good and inserted in calculator.
  2. Turn calculator OFF.
  3. Replace the backup battery.
  4. Turn calculator ON.
  5. Press the [CLEAR] key to erase the "Ram Cleared" message.
