Hi,
As the first step to you diagnosis remove the Main batteries out of the calculator and leave them out for a while. The memory should be cleared.
If that does not restore your calculator you may have to use the procedures suggested by TI for calculators that do not turn on.

Hope it helps.
Thanks for using FixYa.

    Here is a more rational procedure to follow.


    A Try this before thinking of repairs.



    1. Push the ON button.

    2. Even if you see nothing, press the [2nd] key and release it.

    3. Press and HOLD the UpArrow key until the screen darkens.

    4. You may have to keep pressing UpArrow for a little while before you see anything.
    B If that does not work


    1. Remove one of the AAA batteries.

    2. Press and hold the [CLEAR] key.

    3. Whileholding [CLEAR], reinsert the AAA battery and then

    4. turn the calculatoron.

    5. The calculator should display the message "RAM Cleared".

    6. Release the [CLEAR] key and then press it one more time to remove the message "RAM Cleared".
    C. Third option



    1. Remove batteries including the backup battery for 5minutes.

    2. After the 5 minute period, reinsert all of the batteries and

    3. turn the calculator on.

    4. Adjust the contrast if necessary.
    D. Last option

    The last option requires the reinstallation of the system. So
    to use it you must download the TIConnect 1.6 software from
    education.ti.com. You must have the TI USB SilverLink or the TI Black
    serial cables ready.You must be connected to the Internet.


    1. Remove one of the AAA batteries.

    2. Press and hold the [DEL] key.

    3. Whileholding [DEL], reinsert the AAA battery and then

    4. turn the calculatoron.

    5. The calculator should display "Waiting...Please install calculator software now".

    6. Connect the TI Connectivity cable between the computer and the calculator.

    7. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader.

    8. Follow the on-screen directions to reinstall the calculator's OS.
    Ifthe message "Error! Press any key to turn unit off. Then turn unit backon."
    appears on the graphing calculator, quickly, remove one batteryfrom the
    calculator and reinstall it while the transfer is taking place.

    If all else fails you can contact Texas Instruments at ti-cares@ti.com

My ti-84 silver edition calculator is not working at all. I have changed the batteries and the back up battery and still nothing but the black checkerboard square is on, it wont even let me turn off the...


If your calculator display the checkered cursor it means that the memory is full and you cannot type in anything. Clear the memory by resetting the calculator.
Press [2nd][Mem] then select [7:Reset]
Under the first Menu RAM select 1:RAM then 2: reset

Follow this steps to resolve this problem:

Why won't my calculator type it's just the screen and the marker. won't even turn off by itself just on and does nothing.


If cursor is a checkerboard rectangle that means the memory is full. Memory must be cleared or at least some space freed.
Press [2nd] [MEM][7:Reset][1:All Ram][Reset].
Press [CLEAR] to erase Ram cleared message.

If some third-party program or game is stuck in memory, it should be kicked out of memory.

The calculator will not work and won't let me type anything. The only thing on the screen is a cursor and it is not blinking.


Hi,
What kind of cursor? Is it checkered? If it is the memory is full that is why you cannot type anything anymore.
  1. Delete games,
  2. clear all lists [2nd][MEM][4:ClrAllLists][ENTER.]
  3. Clear entries [2nd][MEM][3:Clear Entries][ENTER.]
  4. If that is not enough reset Ram [2nd][MEM][7:Reset][1:All Ram] [2:Reset][ENTER]. Clear the Ram Cleared message.
Hope it helps

Gives error memory message when tries to change


Hi,
See if the cursor is checkered. If so, the calculator is out of memory.
You may have very little memory available and then wanted to create a table with a very small DeltaTbl (the table step). If the step is small, and the domain is large, very many points will have to be generated and that may make the calculator unable to comply for lack of RAM.

I suggest you free some Ram by clearing the lists, clearing the entries. To do so you press [2nd][MEM][3:Clear Entries] to clear entries, then press [2nd][MEM][4:ClrAllLists] to clear the lists.

Alternatively, you can just reset the Ram by pressing [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]. Then clear the Ram Cleared message and start again your table.

Hope it helps.

I need to reset my TI-89 Titanium


There is several ways to reset the Ti-89 Titanium calculator. Other than the one shown to you by K24674, just hit [2nd] [MEM] [F1] instead of [diamond] [MEM] [F1], then:
Press [1:RAM] then select [1: All RAM] or [2: Defaults] and [ENTER] to reset the RAM.
Since you didn't give him four thumbs up because, he did what you stated. I'll tell you other ways to do a reset. The reason is because, you may have a locked up calculator that seems impossible to reset.

Push [2nd] [MEM] then [F1] [3] [ENTER] for yes to reset everything.

If your have downloaded 3rd party shells, games and programs and your calculator is locked up, you may need to take out all the batteries including the small circular one for about 4 hours or more.

If this doesn't work you will have to deal with it, possibly by deleting out what you can to free the calculator up to start operating properly, and re-installing the OS software.

Actually most people don't even need to reset their calculator memory. It is usually just a single variable that their using that is what hanging them up. Just execute the NewProb command to delete all single variables in the folder that your working in by pushing [2nd] [F1] [2] [ENTER]. This only deletes single variables a to z. This method is unlikely to miss you up with other programs, functions that are not archived or can be mistakenly deleted on your calculator. Works real good while working out of the main folder. Hope this helps you!

Memory menu doesn't work.


If you are willing to reset it, hold the "CLEAR" button while you take out the batteries and then let go of clear, then put the batteries back in, and if that don't work, reverse the last two steps, and if that don't work, I suggest that you get professional help
