Hi imagenius1,

You need to free up some memory. Try clearing your RAM memory. Your calculator should operate properly afterward.

Press [2nd] [MEM] [7] [1] [2]

If the steps above did not reset the memory to your Ti 83 family calculator try the procedures below.

Please be prepared to re-install the calculator's OS if you run through this process.

If you have a straight Ti 83 without the Plus or, Silver Edition label goto (Procedure 2) below. If your Ti calculator is a Ti 83 Plus or better goto (Procedure 1).


(Procedure 1).

  1. Try a new set of AAA batteries.

  2. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and, then press [CLEAR] one more time to remove the message.

  1. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator 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.



  2. Steps to re-installing the operating system:
    ~Connect the TI Connectivity cable between the PC and the calculator.
    ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
    ~Follow the on-screen directions to reinstall the calculator's OS. If you could not install the new OS on your calculator goto step 4.


  3. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

  4. If the above process did not reset your calculator. Try re-doing (Procedure 1) and, extend the time in step 4, by 5 minutes to 10 minutes before you put all the batteries back in the calculator.

(Procedure 2).


For a straight Ti 83 without the Plus or, Silver Edition label try the procedure below.


  1. Try a new set of AAA batteries.



  2. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the AAA battery and then turn the calculator on.

My TI 83 Plus won't turn on, I adjusted the brightness, held DEL while reinserting batteries, replaced batteries but nothing changed


hi bckyshldn,

Did you remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. In the procedure that I give, you hold [DEL] and, re-insert 1 battery. I'm going to go ahead and, restate my instructions for a ti 83 Plus that won't turn on.

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me anybody could make the same mistake. and of course the calculator will never come on if the batteries aren't in correctly.

The process below should reset your calculator.

Please be prepared to re-install the calculator's OS if you run through this process.

Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.


  1. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],
    reinsert the AAA battery and then turn the calculator on. The calculator should display the
    message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. If calculator did not display the message try pressing and releasing the [2nd] key followed by pressing and releasing the up arrow for one second. goto step 2.
  2. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator 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. If the calculator did not turn on connect the calculator to the computer and open Ti Connect. Next, open Device Explorer. Is the calculator asking to be installed? goto step 3.
  3. Steps to re-installing the operating system:

    ~Connect the TI Connectivity cable between the PC and the calculator.
    ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
    ~Follow the on-screen directions to reinstall the calculator's OS. When or, if the calculator install the fresh OS goto step 4.


  4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.


If the above process did not work. Try re-doing the procedure and, extend the time in step 4 by 5 minutes to 10 minutes before you put all the batteries back in the calculator.


Now just in case this calculator wasn't posted correctly. Here's my instructions for a Ti 83 that won't turn on. This is not the same procedure that the Ti 83 Plus has.

  1. Try a new set of AAA batteries.
  2. Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.
  3. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the
    AAA battery and then turn the calculator on.
  4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. And of course if the calculator does not turn on, I re-do the procedure and, increase the amount of time by 5 minutes to ten minutes that all the batteries are removed.

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 the operating system on a calculator with low batteries. Users will need to use the TI Connectivity cable and the TI Connect to send the operating system to the calculator. Make sure to have the latest version 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.
If the message "Error! Press any key to turn unit off. Then turn unit back on." appears on the graphing calculator, quickly, remove one battery from the calculator and reinstall it while the transfer is taking place.

If that does not solve the problem, you should contact Texas Instruments at ti-cares@ti.com or www.ti.com/calc.

The batteries were all just replace including the lithium and it won't work I don't have cables with it does it need a download.


Hello,
Usually, you should not change all batteries at one go.

It is likely that the calculator is ON, but the screen is too light to enable user to see anything. If that is the reason, you can darken the screen.
Press the [2nd] key and release it. Press and hold the UpArrow till screen darkens enough.

You can reistall the system (if needed) by connecting it to a working TI83Plus calculator. You need the calc-to-calc cable.

If that does not work, here is what the Texas Instruments Knowledge Base says about the calculator not turning on.

Without further delay, here it is from the horse's mouth (TI Knowledge base)

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.
