You need to re-install or, update the Ti 84 Plus OS. Since you just bought the calculator it is unusual that it is already to that point of clearing the RAM. You can connect a computer and your Ti 84 calculator together once you downloaded and, installed Ti Connect software on the computer. That way you can use the Ti OS Downloader that comes with Ti Connect software to install the newest Ti 84 Plus OS. Or, if you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the IO link ports and, they can send you a copy of their OS while you receive it on your Ti 84.

Get this problem fixed as quick as you can. You do not want your OS to fail any more than what it already has. If you can not find another calculator to connect too, then you can connect through your computer. You may have a long road ahead of you getting the Ti Connect software and, drivers working right. Just remember to come back to your posting here and, post a comment of what ever is failing. This will notify me right away and, I'll walk you though it if necessary.

    Texas Instruments has just came out with Ti 84 Plus OS 2.55v. You can still use my instructions and, link to my other posting to get there and download it. If you suspect that the Ti OS Downloader isn't giving you the updated OS, just follow my Procedure or step 2 to get the Ti 84 Plus newest OS 2.55v. To get to my other posting to download the newest Ti 84 Plus 2.55v just paste the link listed below to your address bar and hit Enter. Once there just follow Procedure or, step 2.

    If you are using Windows 7 and, having trouble installing and connecting through Ti Connect go to the link listed below and follow Procedure 3. The other Procedures at this link listed below are for the Ti 89 but, will work and, are the same for Ti 84 Plus. Only the names were changed.

    If this calculator is still unresponsive after you attempt to send the new OS, open it up in Ti Device Explorer. If it opens try deleting out small non important programs and, lists. Don't delete any 3rd party software. Once you freed up enough memory turn it off and, back on again. It should be more responsive. If so or not, comment at this posting to that fact, and I'll give more information on reset procedures or, possible fixes.

    If your Ti 84 Plus will not turn on and , you can try this procedure but, make sure your ready to install the OS, if the calculator does come on. Try removing one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL] key, reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now." Now connect the calculator to the computer and, use Ti OSDownloader to install a new OS. I'm hoping the calculator will come back on when you re-insert the one battery. It be better to follow Procedure (1), in the instructions to install the OS at the link below but, I figured you'd be happy if it come on and, easier to use the Ti OSDownloader.

    In your case instead of saying, "if the calculator come on," I should of said, "becomes responsive." These last 4 set of instructions might work for your calculator, since it's just lock-up.

My son has a TI-84 Plus calculator and it is completely frozen. There is a message on the screen that reads " RAM cleared". Below that message it says "Press ALPHA F1-F4 to locate shortcut menus" but it...


The calculator OS has been upgraded to the version 2.53 MP.
For this version, whenever you remove batteries (or replace them) and turn calculator ON, you are reminded to Press [ALPHA][F1-F4] to locate Shortcuts Menu.
The calculator also asks the user to press either
[1:Do NOT show Again]
[2:Continue].

Here is what these cryptic messages mean.

Certain functions implemented on the new OS are available by pressing the [ALPHA] key followed by F1, F2, F3 or F4.
Since you may forget how to get to them, the calculator gently reminds you that there are other functions accessed only by pressing the [ALPHA] key.
It also gives you the option to flash the reminder every time the calculator memory is reset (CONTINUE) or NOT to SHOW the REMINDER again.

Usually after the RAM cleared message, press [2:Continue] or any other key but [1: ] to keep being reminded how to access the new functions.
Once a key is pressed the screen is cleared and you have the solid blinking cursor.

My TI-84 Plus calculator won't work. It won't switch off by itself. When the batteries are reinserted, it says that all RAM has been cleared. When i press the 'ON' button again, the screen clears. but...


The Ram cleared message is normal after you change batteries. When you see this message you press the CLEAR button to erase it. You do not press the ON button again because the calculator is already ON. If you want to turn calculator OFF you press [2nd][ON] (OFF).

On certain calculators, pressing the ON button when calculator is already ON is interpreted as INTERRUPT the current command.

I have a TI 84 plus silver edition. Won't turn


The problem may be due a screen that is too light to see anything on it. Adjust the screen darkness.
  1. Press [2nd] key and release it.
  2. Press and HOLD the [UpArrow] to draken screen.
  3. Release the [UpArrow] when screen is dark enough.
You can also connect it to the computer to see if TI Connect finds it. If it does, update the OS to version 2.53MP.

You change the backup battery if the calculator tells you RAM CLEARED each time you turn it ON.

I press the on button and it says TI-84nPlus 2.40 RAM cleared. When I click it lags and takes forever. I have already taken the batteries out and tried to solve it that way but nothing works. PLEASE HELP


Hi,

First, turn it on. Once the calculator is on, press the "2ND" key (I believe it is a blue key in the ti-84 plus silver edition). Now press the plus key (+). A little above that key, you should see the word "mem." When you see the screen titled MEMORY, move the cursor all the way down to the option that says "Reset." From here, you can choose to reset either the RAM memory, or the factory settings. The factory settings are the "Defaults" option. I hope this helps.

Thanks for using FIXYA!!!!!!!!!!!!!!.

TI-84 Calculator does not turn on.


Hi,
The applications that run on the TI84Plus Sliver Edition run without a hitch on the TI84Plus and also on the TI83Plus. The only major difference between the 84Plus and the 84Plus SE is the amount of flash memory.
Here is what I would suggest to you.
  1. Replace the main batteries with fresh ones.
  2. Adjust the screen contrast: a. Press [2nd] key and release it. b. Press and HOLD [UpArrow] to darken or [DownArrow] to lighten screen.
  3. Clear the calculator Ram. Usually it is cleared if the calculator is left without main batteries for a while,but you never know.
  4. To clear the Ram, press [2nd][MEM][7:Reset][1:All Ram][2:Reset]. Press [CLEAR] to erase the "Ram Cleared" message.
  5. Go to the education.ti.com, and download the TI Connect software, if you do not have it already.
  6. Install it on the computer and run the program.
  7. Then connect the calculator to the computer using the TISilver Link USB cable or the Standard USB to mini B cable (if you have one).
  8. Turn you calculator ON
  9. In the TI connect program window, press the Updates button.
  10. The TI connect should recognize you calculator and ask you what to download.
  11. At first select to download the latest OS (version 2.43 at this time).
  12. Later you can click the Updates button and select the Latest version of the applications installed on calculator.
If you calculator does not suffer from hardware problems, your calculator should be restored to health.

Hope it helps.

TI 84 plus calculator refuses to graph more than one function


Hello,
Please, read the following, even if you already know some of its contents.
  1. Once you enter an equation, the corresponding equal sign is highlighted by default.
  2. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted.
  3. If one is not highlighted, move the cursor on it and press ENTER.
  4. If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER].
  5. Command PlotsOff echoes on main screen.
  6. Press [ENTER], screen displays Done.
  7. Restart the graphing procedure.
  8. If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.
You should make it a habit to clear the RAM every time you start a new type of problem.

Hope it helps.

RAM CLEARED?


Hello,
The most likely reason is that the backup battery is drained. Change the backup battery. When you get the Ram Cleared message, just press [CLEAR] to erase the message and start using the calculator.
Hope it helps.

When turned on, my TI-84 Plus says that the RAM is cleared. I pressed on again but you can't do anything after that.


Hello,
If it is always saying RAM Cleared when you turn it on, it may be due to a depleted backup battery. Once you change it, you will not get the message again.
Anyway, you are not supposed to press ON again when calculator is turned on. Just press [CLEAR] to erase the message and have access tho the main calculator screen.
Good luck.

RAM Cleared


This is kinda a weird situation. Because it's usually the other way around. Your ram will clear if your calculator is frozen. So take out all 5 batteries from the back. Even the back up battery. Then reset it again. 2nd then + then 7 then 1 Then 2. Good luck.
