The backup battery is to preserve the contents of memory while you replace the main batteries. If you don't care whether the memory remains while you do this, then you don't need the backup battery. The calculator won't work without the AAA batteries, but will work without the backup battery.

Wont turn on


Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to assist you. You are having problems because you calculator won't turn on. I think you should try changing the batteries. Did you know that your calculator has two batteries powering it? Not only are the 4 AAA batteries powering it, but there is also a CR 3V Lithium Back Up battery powering it as well. First, try changing the 4 AAA batteries. If that still does not power your calculator properly, you will need to replace the lithium back up battery. You can find this at a department store or store that carries electronics. To do this, open your regular battery compartment. Above the AAA batteries is a compartment that says "BACK UP BATTERY CR1616 OR CR1620" with a picture of it. Use a small crosshead screwdriver to open the compartment. Take the old battery out and replace it with the new one. Rescrew the lithium battery compartment back on and close the AAA battery compartment. Turn on your calculator and see if that works. I hope this solution solves this.

TI 82 Does it need the disk battery and 4 AAA batteries to work?


No. The calculator runs on the four AAA batteries. The lithium battery is solely to retain the contents of the memory while you change the AAA batteries. If you don't care about retaining the memory, you don't need the lithium battery. You do, however, need the AAA batteries to use the calculator.

My calculator has fresh batteries and will not turn on, it has normally worked before and now it just randomly stopped working.


Did you change the AAA batteries and the internal back up battery? It may sound unnecessary, but sometimes these devices are a little picky. I would also check that the contrast and brightness setting is appropriate. I fixed my dad's just by hitting second and up on the arrow to make the font show up again.

If neither of those work, try these:
(These will reset the calculator and erase the memory)

Remove one of the AAA batteries, hold down on the DEL key while reinserting the AAA battery. The handheld might display "Waiting...Please install calculator software now". If you get this message, the information in the "Correcting the Error Waiting" section shown below will help you correct the problem. Before trying that procedure, reinstall one of the AAA batteries again. This time do not hold down the DEL key.

Remove one of the AAA batteries, press and hold the [on] key for 10 seconds, release, replace the battery, then turn the unit on. Adjust the contrast.

Remove the AAA batteries for three hours. After the three hour period, reinsert the batteries and turn the handheld on. Adjust the contrast if necessary.

My screen turns on but when you do anything it has random numbers, line and letters on it and i need to get it fixed immediatley


I've had this issue before with my TI-83 Plus. I'm not sure exactly the solution I used, but these steps progress through the mildest to most extreme methods of fixing the calculator.


Solution 1: Take the batteries out.

Odds are you've tried this already, but it bears mentioning.

With the calculator on, remove the triple A batteries housed in the back. After a few seconds, replace them and turn the calculator on.


Solution 2: Clear the RAM.

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.


Solution 3: Reinstall the operating system

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"

Here is the website to reinstall your OS. First you'll need the TI-Connect software.


Solution 4: Remove all sources of power. This is a risky move, but if your calculator will absolutely not work after you try even reinstalling the operating system, it might be your last hope.

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.

I have a TI84 plus texas instruments i have removed both the batteries in order to reset the unit but it still has not resetted the unit. All I am getting all zeros on the screen


First try removing all four AAA batteries and the small lithium backup battery (above the four AAA batteries). Leave all batteries out for five minutes, then replace them and try to start the calculator. If this doesn't work...

Replace all but 1 AAA battery. Press and hold the "CLEAR" button on the calculator. While holding the "CLEAR" button down, replace the missing AAA battery. While still holding the "CLEAR" button, turn the calculator on. The display should read "RAM Cleared". Release the "CLEAR" button and press again to remove the message.

If that doesn't work, remove 1 AAA battery again. Repeat the preceding instructions with the "DEL" key: With the battery removed, press and hold the "DEL" key. With the "DEL" key held down, replace the battery and turn the calculator on. The screen should say "Waiting... Please install calculator software now." Release the "DEL" key. Download this program onto your computer (from Texas Instruments). Connect the calculator to the computer using the USB cable provided with purchase. Run the TI OSDownloader program and follow the on-screen instructions to re-install the calculator's operating system.

There is a battery compartment on the back of the calculator, about 2" by 3". It has a tab that must be depressed in order to open. Try putting new batteries in it. It should take 4 AAA batteries.

I did not reset or delete anything on my TI-84 calculator but after i changed my batteries i went into my programs but my programs were not there... do you know how to get my programs back?


You should not remove all the batteries ( AAA and backup) at the same time. Rather change the AAA batteries leaving the backup battery in. Then if you have to, change the backup battery while the AAA batteries are inserted.
If you do not take this precaution, you lose programs.

To reinstall programs that shipped in calculator (or additional apps) go to the education.ti.com page by clicking this link Download what you need and use the TI Connect software to transfer the APPS to your calculator.

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).

  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.

Do i need both the back up lithium battery and the 4 AAA batteries for my TI-83 calculator to work? Or can it work only with the 4 AAA?


The calculator can work with just the AAA batteries. But, without the backup battery, you'll lose all the contents of memory when the AAAs die. The backup battery is intended to keep the contents refreshed while you replace the AAAs.

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)

I hope it helps.

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

Caution: The resets described in these troubleshooting steps will cause a loss of 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 by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
  3. 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.
  4. 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 TI83-family or Ti84 Plus family to reinstall the calculator operating system (see below.)
  5. 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.

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 touse 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.
