Lag + Doesn't shut off... (ti84plus)

Hey,
So my calculator has been acting really funny right now..
When I turn it on, the cursor does not flash, the buttons have to be held for about 3 seconds before they do anything. The unit also does not turn off or sync to the computer (i just take the batteries out). When i put the batteries back in the calc behave the same as before saying ram cleared when it turns on...

please help I have finals coming up in 3 weeks....
Thanks
John

    I'm a teacher, and one of the calculators in my classroom set does the exact same thing. We thought the batteries were dead, we replaced them with brand new batteries, and it still barely functions. If I hold the buttons down for much longer than it should require, it responds. The cursor never flashes when the calculator is on. I tried clearing the memory and the ram, but that didn't change anything.

    My calculator just lags completely and when turned on after a new set of batteries all it says is "ram cleared" with the TI model on top. I will be holding buttons for 3-4 seconds and my calculator won't turn off. What do I do to stop it from lagging, what certain programs do I delete? My calculator is a TI-84

The I/O plot matters. If blowing doesn't help, insert a stick or something into it. I had the same problem, and my TI 84 plus had already been extremely unresponsive and slow before, as I fixed the latter problem by blowing really hard into the I/O plot, I did the same to fix the new problem. For many times nothing happened. Then I insert a metal stick into it and gently hit it inside. In a short while, the calc was normal again!! Now my calc even turns on when it's been put off, with its cursor frozen. I simply use my little finger to dig/scratch the plot and see the lovely cursor beating again. PS Having such a funny calc is really bad, but every time you fix it you'll feel good

I actually fixed mine!!!! The same thing happened to me. I found somewhere that the no/slow key response could be due to a short in the I/O socket. I blew into it really hard (you may want to use compressed air, but I didn't have any onhand), and it works perfectly now!!!!!!!!!! I hope this helps.

Is there a way to change so that the symbol shows up for abs


In the older OS the absolute value function is a command called abs(, and which you will find under the MATH menu.
To access it, press the [MATH] button, then use the right Arrow to highlight the NUM menu. The abs( function is entered by pressing [1:abs(]. You will have to complete the function by supplying the argument and closing the right parenthesis.

If you calculator has the newer version of the Os (version 2.53MP) and the calculator is configured to use the Math Print Input/Output mode you may be able to see the two vertical bars. (I cannot be sure because I no longer have a Physical TI84 Plus calculator as I use the TI-Nspire with The TI84Plus keyboard. The Os for the TI-Nspire TI84Plus is 2.54MP.)

I am a teacher art Rutgers in NJ. I have a student with a T1-84. When she enters two functions in the "Y=" screen, only one graph is displayed. e.g, y1=x, y2=x^2, only the line y=x is displayed when she...


The TI84PLUS and TI84Plus Silver Edition usually ship with a dynamic geometry application called Transfrm. If it is executed it loads in memory and lingers there until it is "uninstalled."

When in memory it takes over the graphing capabilities of the Native OS. and prevents the user from graphing more than one graph. This is understandable because it is upposed to be used with varying parameters.

To restore the graphing to the Native OS Transfrm must be uninstalled (not deleted).
To do so:
  1. Press [APPS]
  2. Use UpArrow to move cursor rapidly to the bottom of the APPS list, or use DownArrow to get to the bottom of said list.
  3. Select [:Transfrm] and press [ENTER].
  4. On the subsequent screen you are invited to [CONTINUE] Or [UNINSTALL] the APP.
  5. Press the number that corresponds to UNINSTALL.
  6. TRANSFRM will be kicked out of memory, and the OS regains control of the graphing.
  7. Go to [Y=] editor and enter the functions.
  8. Make sure the [=] on Yx= lines are highlighted.
  9. If some = are not highlighted, move cursor to each one and press [ENTER].

Can't download the operating system with Vista. Running the downloader under Admin


Hello,
You can use the calculator-to-calculator procedure to transfer the operating system of a working compatible calculator (TI84Plus or TI84Plus Silver Edition).
On ticalc.org I found an article in which the author says that he has been able to use TIConnect with Vista Home SP1 32bits.
I suggest you read the article.

Hope it helps.

TI 84 plus calculator, flashing dot in upper left hand corner


Hello,

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.

Hope it helps.
