Question about Texas Instruments TI-83 Plus Calculator

1 Answer

I have a TI-84 and about a month ago or so the display response got very very slow. I mean, you have to hold the key for ~2s or so for it to show up, so obviously doing anything takes forever. I don't know what it's wrong with it--I tried switching batteries and so on, but still nothing. It actually worked briefly after I put in a brand new clock battery, but quickly returned to its sluggish state. Does anybody know what may be wrong, how to fix it?

If you cannot see anything on the screen, you may need to adjust the graphing TI 84 calculator contrast :

1.To darken the screen, press and release 2nd key, and then press and hold up-arrow key until the display is sufficiently dark.

2. To lighten the screen, press and release 2nd key, and then press and hold Down-arrow key until the display is sufficiently light.

Ti 84 plus wont work


TI calculators have an annoying habit of dimming the screen, especially 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.
If this isn't the problem, please reply to this post and give a fuller description of the problem.

My ti-84 plus it does not respond to the function + or - OR other function, & it come up to display very slow ,slow. thanks


Hi xvbanh,

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

Go to [2nd] [MEM] [7] [1] [2]

If your calculator still won't let you delete the RAM memory try the procedure below.

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.

From TI FAQs:

What troubleshooting can I try if the TI graphing calculator will not turn on?

For the TI-83 Plus Family, TI-84 Plus Family:
Caution: The resets described in these troubleshooting steps will cause a loss of applications, programs and data. If at all possible please create a backup using TI Connect™ first.
  1. Try a new set of AAA batteries.
  2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
  3. 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.
  4. 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.
  5. 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.

Comma key on TI-84 Plus Siver Edition calculator.


The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is.

TI 84 moving slow-have to hold buttons downv


If a piece foreign material such as a pencil lead is lodged in the I/O port of the calculator, it may create a short causing the calculator to respond slowly to key press entries.
If the piece of conductive material can be removed, it may restore the calculator to normal operating condition.

TI-84 frozen


The same thing happened to me. I found somewhere that the no/slow key response could be due to a short in the I/O socket. I blew into it really hard, and it worked perfectly after that. I hope this helps.

TI-84 Plus Silver Edition - Slow or no response


Blow in the i/o socket on top of the calculator. There's probably some dust stuck in it or something.
