Ti-84 frozen

If your programs are archived you can remove the main AAA batteries without losing them. If they are stored in RAM they will be wiped out.
Just do not remove the Main AAA batteries and the button cell backup battery at the same time.

A program slows my Ti down, but only after 5 sec.

Your program is depleting the RAM. You may be creating too many graphics and when you no longer need them, you are not erasing them from inside the program. 24KB is easily used up. It is also possible that some calculations(if you are doing calculations?) are not converging. Recursion can be quite involved and they take too much time.
What can I say? Even a small program badly designed (no reflection on your abilities) may misbehave after a few iterations.

We have a TI-89 and it is froze on the home page. we tried holding the 2nd button , left arrow , rigth arrow and pressing the on button. it comes up with installation in progress , but when that is done it...


Here is a procedure to reset the TI-89 to factory settings (found online):

  • Press the "Snd Mem" key to display the memory screen.
  • Press the "F1" key.
  • Press the navigation key to select the "RAM" icon, then select "1: All RAM" to erase all data and programs from the random access memory and press the "Enter" key, or select "2: Default" and press the "Enter" key to reset all system variables to original factory settings. This preserves any user-defined variables, functions and folders.
  • Press the navigation key to select the "Flash ROM" icon, then select "1: Archive" and press the "Enter" key to erase all data and programs from the read-only memory or select "2: Flash Apps," then press the "Enter" key to erase all applications from the Flash ROM. Select the "All Memory" icon and press the "Enter" key to erase all data, programs and flash applications from the RAM and Flash ROM.

  • Hope this helps.

    Trying to use a program i created and have used many times already, i got the message "variables or flash applications is locked, protected or archived"... can i fix this without erasing my...

    If this problem is when you try to edit it then go to the Var-Link menu, find your program, if it has a little lock next to it, press F1, 7 (this unlocks the program), if it has a star press F1, 9 (this unarchives it). that should allow you to access it. If the problem is when you run it go to the Var-Link menu, find any variables your program accesses and do the same thing as before for your variables.

    The ram was erased from my TI-84 calculator, how can I get it reinstalled to my calculator through my computer

    The RAM is the working memory. Its size is about 24 kB. Applications and other archived programs are stored elsewhere. What was in RAM and was erased, you cannot recover.
    If you lost applications, just go to Download apps and programs, and download applications to your computer, then transfer them to the calculator.
    You can do the same for programs you got from the Internet. Anything you typed ypurself must be reentered. Sorry, but that is the way it is.

    When I turn on the calculator, the screen is stuck with various symbols. What is up with this? How do I get it off?

    This is not the normal behavior of the calculator. What third party games or programs do to the calculator, I have no idea. Terminate the game or application or program that was running either from inside the program (Press the first row keys to find EXIT, or END) or with [2nd][QUIT] or reset the memory. To do the last press [2nd][MEM][7:Reset][1:All Ram][2:Reset][ENTER]ENTER]. Press [CLEAR] to erase the Ram cleared message.

    Hope it helps.
    Thanks for using FixYa.

    Encrypting TI-84 programs I've seen this with other programs, but even as an experienced programmer i can't quite encrypt programs. By that I mean: if i see a list of my programs under the 'execute' menu...

    The program is protected with a password, or it is archived. Unarchive the program. Under [2nd][CATalog] Press [2nd][ALPHA] U to jump to the first command in catalog that starts with U. Scroll down to Unarchive [ENTER]. Command is echoed on main screen, Feed it the name of the program and close parebthesis then press [ENTER]
    Unarchive( program_name ) [ENTER].

    I found out that reistalling the OS got rid of passwords on programs.

    Hope it helps.

    Need to erase all programs

    There are two ways of doing this.
    Hit the 2nd key
    Then the "+" key
    Then the 7 key
    Then the 1 Key
    then the 2 key
    This will delete your whole ram. and clear everything. your calculator will be fine but all your list and data that you might have will be gone
    Or You can
    hit the second Key
    then the plus key
    then the 2 key
    Then hit enter
    and you can delete the programs you want by pressing the del key
    This will just delete your programs and nothing else
