    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.

There are three possible solutions here. From what you are describing to me, you say the screen displays a couple of random numbers and letters, including a solid vertical line in the upper right corner, are scattered across the screen? Sounds like you are still in graphing mode. There is nothing wrong with your batteries and changing them won't help because I already know that you didn't change the CR Lithium Battery. This is the "memory card" for the TI-83 Plus. If you don't change that, when you insert new AAA batteries in the calculator, the memory has not been deleted. You probably don't remember, but the calculator remembers the last problem that you did, which was a graphing calculation. Try pressing the "Graph" button and the calculator will go back to function mode. If this doesn't work, try resetting all the memory.
  1. Remove a battery from the battery bay.
  2. Press and hold the CLEAR button while re-installing the battery.
  3. While still pressing the CLEAR key, press and hold down the ON button. If the home screen displays, release the keys.
  4. If the home screen is displayed, press 2nd MEMto display the memory menu.
  5. Select 7:Reset to display the "RAM ARCHIVE ALL" menu.
  6. Press the right arrow twice to display the "ALL" menu.
  7. Select 1:All Memory to display the "RESET MEMORY" menu.
  8. To proceed with the reset, select 2:Reset. The message "MEM cleared" is displayed on the home screen.
If this doesn't work, try changing the CR Lithium Battery. It is located in the battery bay at the top with the cross-head screw in it (It says BACK-UP BATTERY). It tells you what type of battery it takes and how to insert them in. I hope these possible solutions help. If all of them don't, then the only other thing I can think of is that it has some internal part alignment issues or a cold soldering iron blob, on the inside of the calculator. I saw one time on the Internet that cold soldering irons can sometimes make electronics not work properly.

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.

TI-84 Plus calculator goes on, but says "RAM cleared". Then, the cursor does not flash, and I have to push the buttons for a long time to get anything on the screen. Also, if I push the same button more...


Read about the nature of the cursor. It can be on Insert or overwrite. If the cursor is full square and flashing, that mean the memory register for the input line is full and you cannot input anymore strokes.

How to fix a none responsive button in hp 35s calculator


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

THE CASIO HR-100TM HAS AN E ON THE SCREEN AND THEREFORE I CANNOT USE TH MACHINE. HOW DO I REMOVE THE E


First, check the batteries, and ensure there is not a paper jam in the printer.
If both are fine, then while the calculator is in the "Print" mode, press the [CA] (or [AC]) button 20 times consecutively to clear out memory buffers. Try some numerical calculations, and if the problem persists, repeat pressing the [CA] button 20 times.
If the problem still persists, then the calculator may require service.

My Ti83 silver edition will not turn on.


I'm not sure if this will help you patchesb7; it sounds like your calculator is having issues :(
This will help others whose calculators suddenly won't turn on anymore, even after changing the batteries.

Note:
This will return the calculator to the way it was when you got it out of the package. Any data or programs have stored since will be lost.

Step 1: Remove all four AAA batteries.

Note: You will have to hold down the CLEAR button while doing Steps 2 and 3. Do not let go until after you have pushed ON in Step 3. I found this easiest to do by holding the calculator upside in my left hand with my pointer finger holding the CLEAR button so the ON button was easier to access.

Step 2: Hold down the CLEAR button (located under the arrow keys) and reinstall the AAA batteries.

Step 3: Press ON button and then let go of both buttons. The screen should say the RAM has been cleared. Press CLEAR to continue.

Casio FX-9750G Plus won't turn on


I had the same problem too. I just bought it and I was trying to turn it on but it wouldn't though the manual said that it was supposed to automatically when the tab was pulled out. Good news: the Reset button on the back works. I pushed it for some time with the end of a toothpick and it worked.

hope it helps.
