Could be the screen has been dimmed so much that you can't tell that it's coming on. Press on and then 2nd button and the up arrow key. You may need to keep pressing 2nd and up arrow key. This is how you darken the screen. You can also lighten the screen which may be the problem you have by pressing 2nd and then the down arrow key. This is how the contrast is controlled on your calculator

If this doesn't work, take out the internal battery that is located in a tiny door with a screw right above the 4 AAA batteries. Leave this out for about 8 hours and put it back in. Put in the AAA batteries and the calculator will be reset and may work.

Ti 84 water damage


TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

When i turn my calculator on it says "RAM cleared". It is then very slow . . . what is wrong and how can I fix it?


Hi yeager anna,

Since the calculator operates slowly even after the RAM has been cleared, I'd say, "Your OS must be corrupt." You need to re-install the Ti 84 Plus OS, ASAP!!! You can fix this problem by installing the newest Ti 84 Plus 2.55v. MP OS, operating system. Use fresh batteries when installing the new OS. If you need additional instructions your welcome to read my Ti 84 Plus solutions. I pretty much tell how you can install the new OS with another Ti 84 Plus calculator or, connecting the computer to the calculator to install the new OS. You can view my solution to install OS by clicking, "Ti 84 Plus OS installation." Just stroll down to oneplusgh's solution at that posting and, I cover a lot of topics you may need advice on to install the new OS.

If you need instructions to downloading and installing TI Connect on a XP or, Mac computer click, "TI Connect on a XP or Mac computer." I realize this posting was for a later OS but, this link will take you to the latest TI Connect software and, newest OS too. Once you get the TI Connect software installed come back to this posting and, follow the instructions above at "Ti 84 Plus OS installation."

If you need instructions to downloading and installing TI Connect on a Windows 7 computer click, "TI Connect on a Windows 7 computer." Just follow Procedure 3. You can also get instructions at this link on how to install the Ti driver to link computer and calculator. I realize this link instructions were for a Ti 89 calculator but, they will work for a Ti 84 Plus too. Once you get the TI Connect software installed come back to this posting and, follow the instructions above at "Ti 84 Plus OS installation."

My instructions is geared to save you a lot of hardship. No matter if your having to install Ti Connect or, the newest OS for your calculator. I do not use TI OSDownloader because, TI OSDownloader might not give you the newest OS for your calculator. My instructions will. If you have any questions just post a comment and, I'll respond quickly.

I changed the batteries in my ti-84 and it will not turn on.


Double check that all the batteries are new, and that they are all completely in and in correctly. Also, it may be an issue of screen contrast. Hit the "2nd" button and then press and hold the up arrow. If you don't see anything, press "On" and try the same process again.

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.

TI 84 won't turn on. New batteries installed. TI Connect recognizes device and I installed new OS. Brightness is not the issue. Any suggestions? This is one of student's calculators. Thank you.


Sorry, answer was posted as a clarification request.

Hello,
Here it is from the horse's mouth (TI Knowledge base)

For the TI-83 Plus Family, TI-84 Plus Family:


Caution: The resets described in these troubleshooting steps will cause a lossof applications, programs and data. If at all possible please create a backup using TI Connect™ first.
  1. Try a new set of AAA batteries.
  2. Adjustthe contrast by pressing and releasing the [2nd] key followed bypressing and releasing the up arrow; repeat as necessary. To adjust orlighten the display, use the down arrow.
  3. Remove one of theAAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],reinsert the AAA battery and then turn the calculator on. Thecalculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.
  4. Removeone of the AAA batteries. Press and hold the [DEL] key. While holding[DEL], reinsert the AAA battery and then turn the calculator on. Thecalculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system (see below.)
  5. Removeall of the batteries including the round lithium battery for 5 minutes.After the 5 minute period, reinsert all of the batteries and turn thecalculator on. Adjust the contrast if necessary.

Reinstalling the OS fot the TI84Plus

How do I correct the Error Waiting...Please Install Calculator SoftwareNow message on my TI-83 Plus family or TI-84 Plus family calculator?

If an operating system (OS) update fails or is interrupted, the calculator will be in an inoperable state with the message Waiting...Please install calculator software now.The most common cause of a transfer being interrupted is updating theoperating system on a calculator with low batteries. Users will need touse the TI Connectivity cable and the TI Connect software to send theoperating system to the calculator. Make sure to have the latestversion of TI Connect installed on the computer.
In order to install the software please follow these steps:
1. Connect the TI Connectivity cable between the computer and the calculator.
2. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
3. 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.

Hope it helps.

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.
