Ram cleared on online ti 83 calculator. how do i fix it?

It is possible that the backup battery is depleted and cannot keep the RAM refreshed when the calculator is turned off. I suggest you change the backup battery immediately.

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.

Press [2nd][+] to access (MEM)ory management. Select [7:Reset][1:All Ram][2:Reset].
Calculator answers "Ram Cleared". Press [CLEAR] key or any key to get the main calculator screen.
By resetting the Ram you will lose any information that is not archived (data in lists, defined functions, graphs, etc.)

It calculator tells you Ram Cleared each time you turn it on, the most likely reason is that the backup battery is depleted. Its role is to keep the memory modules electrically refreshed when calculator is turned off. If the backup battery is dead, the memory is erased when you turn calculator OFF. Main batteries no longer supply power and the contents of the memory are cleared.

1. Check that main batteries are good and inserted in calculator.
2. Turn calculator OFF.
   
3. Replace the backup battery.
4. Turn calculator ON.
5. Press the [CLEAR] key to erase the "Ram Cleared" message.
   

Hello,
Well, if screen shows the RAM CLEARED message, that means your calculator is working. Just press the [CLEAR] key, message will be erased and you are ready to crunch numbers.

Hope it helps.

Hello,

RAM cleared means that the machine removed all old values stored in variables. And it is wainting for you to start calculating.
Enter any operation
1[+]1 should give you 2.

If the keys do not answer when you press them and nothing shows on screen you the calculator may have to be repaired.

Hope it helps.

There is a small round battery under a small rectangular cover just above the other triple A batteries. It has most likely gone flat. try replacing it, then see if it works properly.

Hello,
I have just done what you said you had done, but I got a nice, correct table of values. You might have discoverd a secret command to clear memory.

Cheers.

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.
