My calculator was working fine and then all of the sudden none of the buttons work except for the on button. It won't turn off until it auto shuts down, and the number buttons do not work. I just have a flashing square at the top.My calculator was working fine and then all of the sudden none of the buttons work except for the on button.

If a checkerboard cursor ( black square ) is displayed, then either you have entered the maximum number of characters in a prompt, or memory is full. If memory is full:
-Press 2nd then MEM and then 2 to display the MEMORY MANAGEMENT / DELETE menu.
-Select the type of data you want to delete, or select 1:All for a list of all variables of all types. A screen is displayed listing each variable of the type you selected and the number of bytes each variable is using.
-Press up-arrow and down-arrow keys to move the selection cursor > next to the item you want to delete, and then press DEL
Next, enter a matrix into the calculator. To enter a matrix, press the arrow that points to the right two times when the cursor highlights letter "A." This moves the top cursor to "Edit." Press "Enter" to select the "Edit" option.
Next,, enter the matrix's numbers into the matrix on the calculator. Press "Enter" to move the cursor over one column. Press a button that has a dash symbol within parenthesis [( - )] to move down one row. Repeat the steps until the matrix is completed.
Next, Press "2nd" then "Mode" to go back to the home screen. Press "MATRX" to enter the matrix screen again.
Finally, press "Enter" when the cursor highlights matrix "A" then press "[x^ -1]." Your screen should read "[A]^ -1." Press "Enter" again to display the inverse matrix.
In MthIO, pressing the log key displays a template: the log function and two squares, one smaller and below the main line, and another, bigger square/rectangle on the main line.
Use the down arrow to move cursor to the smaller square end enter 2 as base.
Use the up arrow to move cursor to the bigger square and enter the number whose binary log you want to calculate.
Close the right parenthesis.
Press the [=] sign at the bottom right of the calculator.
MthIO is the default Input/Output format of the calculator. To set it
Hello, Between the x`squared key and the log key there is a key with an x with a raised small figure of a solid square. That is the key you use to enter arbitrary exponents.
If calculator is in MathIO ( a Math indicator appears on the upper band of the screen), enter the base of the power (here 2). A number 2 with a raised empty square appears.The cursor will blink in the raised square. Enter there the exponent (here 12) and press [=]. Result 4096 appears at the bottom of the screen.
If in LineIO (no Math indicator appears on the narrow band at the top of the screen), press 2 and then the key I talked about above. On the screen a number 2 appears with a hat and a left parenthesis. Type in the exponent (here 12) , the right parenthesis and press [=]. The calculator should display 4096.000...

In the exemples above I used 2^12. But you can enter any base (2, 3, 5.5, 16/47, ) and any exponent ( 12, 13/48, 0.007654, even negative values).
Hope it helps
When you turn the calculator on, its screen is cleared, save for a small square on the top left corner. This is the cursor and it is blinking: The calculator is waiting for you to order it to perform some calculation.
Try this simple operation [1] [+] [1] [ENTER]. The calculator will display the result one line down justified to the right.
I had this same problem on my TI 89...
You must have accidentally set your calculator to insert mode. To switch it back to the thin cursor, input the following keystrokes... Go to the "2nd" key to enter second function mode. Then press the button with an arrow on it pointing to the left(The key that you use to backspace). Do you see the "INS" lettering above the backspace key? There's your solution :-)
