Question about Texas Instruments TI-84 Plus Calculator

1 Answer

My new TI-84 Plus Silver Edition will not turn on most of the time...only on certain occasions. I have put brand new batteries in it. Is there a way I can reset it to turn it on or is it simply a defective calculator?

    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. Does it?

    No, that did not work either.

    If you're willing to lose all the contents of memory, remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Does the calculator now turn on normally (you may have to adjust the screen as described earlier)?

    That didn't change anything either.

Having gone four months without a response, I assume the suggested reset solved the problem.

I was using my ti 84 plus silver edition calculator and the screen got very dim and then it faded out completely. it wont turn on now. i switched the batteries many times, and the calculator is very new,...


If this item is new I would return it, from what you have said the Graphic Calculator has had microprocessor ic failure and there is nothing you can do but return it.

I would suggest putting it in some dry rice. That will soak up all the moisture. You might also try drying it with a hair dryer.

I have a TI 84 plus silver edition. Won't turn


The problem may be due a screen that is too light to see anything on it. Adjust the screen darkness.
  1. Press [2nd] key and release it.
  2. Press and HOLD the [UpArrow] to draken screen.
  3. Release the [UpArrow] when screen is dark enough.
You can also connect it to the computer to see if TI Connect finds it. If it does, update the OS to version 2.53MP.

You change the backup battery if the calculator tells you RAM CLEARED each time you turn it ON.

RAM CLEARED?


Hello,
The most likely reason is that the backup battery is drained. Change the backup battery. When you get the Ram Cleared message, just press [CLEAR] to erase the message and start using the calculator.
Hope it helps.

TI-84 Plus Silver Edition turns off immediately, all batteries have been replaced, but unit still turns off. I even replaced the memory battery.


You may need to reset calculator. Take ou the batteries and the backup battery. Leave them out for about 8 hours. Then put everything back in. Hopefully this will work.
