    My daughter's TI-83 plus has locked up and is non responsive after I replaced the old batteries. I get some calculus functions displayed (tan, sin, or cos) etc. I have been unable to clear any of this. I am unable to turn it off short of removing the batteries. Even removing the backup I still get the same display (tan, sin, or cos) etc once I reinstall the batteries. All keys are still unresponsive.

    Ditto, same problem

    I bought my daughter a TI-83 plus a year ago for her freshman high school year. Recently we replaced the batteries with new ones in preparation for this year. All the keys are nonresponsive. I am unable to clear anything or even turn it off. I even tried removing the backup battery before removing the AAA batteries to see if the memory would be cleared. I still get some calculus functions (tan, sin, cos etc.) displayed when I reinstall the batteries and still can't use any keys.

Here's a solution to some of the problesm. It seems that your calculators are lagging or just messed up. These could be cause by water damage or an object getting into your calc or what ever. Try blowing realy hard into the I/O port. It sounds stupid but your problems may be cause by a short there. Blow for maybe 5 seconds and when you turn on your calculator it should start to work again.

I had the same problem. I found that the contacts between the battery compartment and the calculator's circuit board were bad. If the simpler methods don't work, try this:
1. Remove the back-up battery, using a #1 phillips head.
2. Remove the 6 screws from the back panel, located around the perimeter. Mine required a #5 (I believe) allen wrench. However, the one in the upper left (as you look at the back of the calculator) needed a #6. Don't know if that was unique, or if the screwhead had been stripped some.
3. Using a small flat-head screwdriver, place it in between the front and back cover at the very top of the calculator and pop the back up. Do this in two more places, in the middle of the ribbed areas on both sides of the calculator (near the bottom). The back should come off easily.
4. SLIGHTLY bend the two spring contacts from the main battery compartment so that they'll touch a different place on the circuit board pads. You may want to use an eraser on both the springs and the pads. Be gentle on the circuit board pads, and be careful no eraser bits go inside the calculator.
5. Do the same thing for the backup battery leads and pads as well.
6. Snap the back on, replace the 6 allen head screws, and replace all of the batteries.

This worked for me.

I think this problem may be caused by a small amount of some type of moisture getting into the calculator at some point. Upon further investigation of the problem with my daughter's TI83 plus calculator, I found what appeared to be signs of a small amount moisture in the battery compartment. She comfirmed that one of the batteries she removed looked like it had leaked. We removed all batteries and cleaned all battery contacts the best we could and tried blowing air into it in any opening to dry out anything internal.
You may want to try your hair dryer on a COOL setting for a few seconds or a couple of squirts from can of compressed air from some place like Radio Shack.
Let it sit overnight reinstalled the batteries the next day and the calculator appears to working normally.

My Texas Instrument TI 83 Plus will not turn on?


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. If this doesn't do it, please reply to this post and we'll go on from there.

Are you certain that the batteries are facing the correct direction and have enough juice?

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.

Cant get Y values when i type in X values in table


Hi there,

Well first of all you can try to reset your calculator, just follow the below steps to know how to reset it -

1. Turn off your TI-83 Plus.
2. Open the battery panel on the back of the calculator and remove one of the AAA batteries. Keep this battery handy, as you'll need it again.
3. Press the "Clear" button, and keep it held down.
4. Put the battery back in and turn on the calculator, with the "Clear" button still held down. When the calculator's screen displays the message "RAM Cleared," release the "Clear" button.
5. Remove one of the calculator's batteries again. This time, hold down the "Del" key.
6. Reinsert the battery and turn on the calculator. Release the "Del" key when the screen reads "Waiting...Please install calculator software now."
7. Use the TI Connectivity cable to connect your calculator to your computer. Run the TI Connect software to reinstall the calculator's operating system. If you don't have an up-to-date copy of TI Connect, see Resources.
8. Turn off the calculator and disconnect the TI Connectivity cable. Remove the AAA batteries, as well as the small, circular lithium battery.
9. Wait five minutes before putting the batteries back in. Turn on your calculator.
Hope it helps ..........

Good Luck!!

Thanks
