Question about Texas Instruments TI-83 Plus Calculator

Turns on but does not respond to buttons

I have tried clearing the memory it does not work. Problem: Calculator turns on fine. It does not respond to ANY buttons pushed. Help?

I have the same problem. I can push buttons for a long time until it responds and I can only turn it off by taking out the regular batteries and then it saus ram cleared the next time I turn it on.

Replacing usual batteries will work, but removing the "watch" battery will clear all your RAM, so avoid it. Despite all that, i still can't connect the calculator to my computer via the USB cable, so it might have some undesirable after effects. I guess the hardware is a bit of a pushover, thank god I could fix the problem before my major maths test.

Try replacing both the AAA batteries and the back-up batteries. This should probably fix the problem. If not, contact the guys over at Texas Instruments for replacement parts if you need them.

Somehow I have pushed a button I wasn't supposed to. When I turn the calculator on there is an 'M' on the screen. I cannot remove it. This makes my totals show up with out the cents column.

There is a couple things we can try, press the clear button on the calculator, failing that! remove the batteries for at least 60 seconds to see if it will clear "M stands for memory" the only other thing you can do is locate the M key, press once engages the memory, press again turns it off on some models.

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.

Resetting the Calculator
If the calculator doesn't respond to keystrokes or if it is otherwise behaving unusually, attempt to reset it. Resetting the calculator halts the current calculation and cancels program entry, digit entry, a running program, a SOLVE calculation, an ∫ FN calculation, a VIEW display, or an INPUT display. Stored data usually remain intact.

To reset the calculator, hold down the C key and press GTO . If you are unable to reset the calculator, try installing fresh batteries. If the calculator cannot be reset, or if it still fails to operate properly, you should attempt to clear memory using the special procedure described in the next section. If the calculator still does not respond to keystrokes, use a thin, pointed object to press the RESET hole.
The calculator can reset itself if it is dropped or if power is interrupted.

CLEARING the MEMORY

If the calculator fails to respond to keystrokes, and you are unable to restore operation by resetting it or changing the batteries, try the following MEMORY CLEAR procedure. These keystrokes clear all of memory, reset the calculator, and restore all format and modes to their original, default settings (shown below):

Press and hold down the C key.
Press and hold down the R/S key
Press i (You will be holding three keys simultaneously)
When you release all three keys, the display shows MEMORY CLEAR if the operation is successful.

My TI-89 calculator turns on, but gets stuck on window editor

If you're willing to have all RAM cleared, try a hard reset.

Press and hold the 2ND, Left-arrow, and Right-arrow keys.
Press and release the ON key.

TI-83 Plus Silver Edition problem

These instructions are from education.ti.org, and worked for me.

1) Take out one of the AAA batteries
2) Hold down the CLEAR button
3) Put the AAA battery back in while still holding down the CLEAR button
4) Let go of the CLEAR button and turn the calculator ON
5) Press CLEAR to get rid of the error message.

Then you should be good! All the applications on my calculator were still intact, so despite the error message, the RAM was never actually cleared.

SOLUTION:
blow really hard into the I/O port. It fixed it for me!
