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.

If this doesn't do it, please reply to this post and we can go from there.

The calculator will turn on, flash a number then turn back off. we tried new batteries and nothing worked.


Hi kaybree2306,

Do this RAM reset procedure.

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. The calculator should starts to operate properly.


You may need to do this procedure below after the RAM reset, if contrast is to low.


Pressing the [2nd] key followed by pressing and releasing the [Up Arrow] key. This adjust the contrast in case the contrast was to low. Keep repeating if necessary for about 10 seconds. If calculator comes on and, responds to key functions you should be done.


If your calculator does not start operating properly after this procedure just post a comment and, I'll give instructions to reinstall a new OS for your calculator. I don't think you will need the OS instructions after you do the RAM reset. At least your calculator does come on so, we should be able to fix it.


Installing a new OS has some risk to it. To be ready if needed to install a new OS can you access or, connect to another Ti 84 Plus? Or do you need to connect the calculator to the computer to install a new OS? If so, do you have TI Connect software installed on that computer? Answer these questions in a posted comment and, I'll give the OS installation instruction if needed.

I haven't used the calculator in a long time(TI 83 plus) and I put in a new set of batteries. The old ones that were in left some battery acid, but not much. The calculator doesn't want to turn on. It's a...


hi adamsukienni,

Clean the battery damage up real good. Gently scrape to terminals of corrosion. Back in my day we use to put a little bit of coke cola to clean car battery posts to get a good connection. If you could put a little bit of coke on a Q-tip without getting any inside the calculator that would be good. Just let it soak in for about 30 minutes. And gently scrape the bad areas again clean of the corrosion. You have to clean it up to metal so, that when the battery is in it will be metal to metal connection.

If you can download new OS with another Ti83 Plus or, don't want to install the new OS goto Procedure 1.

Be ready to install the new ti 83 OS v.1.19. So, setup your computer with Ti Connect software and, have the new OS v.1.19 download ready and, in "My Documents \ My TI Data \ Downloads." If you need additional instructions on how to connect the computer to the calculator you can read my instructions at another posting I did. You can go to that posting by clicking, "Connection Instructions," under this paragraph. Just remember the OS was for a Ti 84 Plus and, your's is a Ti 83 Plus so, don't download the OS from the other posting. I'll give you a link below this paragraph to download the correct Ti 83 Plus OS v1.19 for your calculator here at your posting. Just follow the other posting to where I say, "You can also go back and, download the Ti 84 Plus guidebook too, if needed." After that statement the computer and, calculator get connected with the cable and, your not ready for that process, yet! When you come back to this posting and you have downloaded the new OS to the proper folder goto Procedure 1.

Additional computer to calculator connection instructions click, "Connection Instructions."

Ti 83 Plus OS v.1.19 download click, "Ti 83 Plus OS v.1.19". Save this download to "My Documents \ My TI Data \ Downloads".

Procedure 1.
Take all the batteries out for 10 minutes, including the very small one that you have to use a small philips screw driver to get it out. Watch out for the spring under the small battery, it might pop out. Replace all the batteries after 10 minutes with new ones, including buying a new small battery. The small one might cost about $5. I know it is expensive but, this might work.

A battery reset procedure should bring your Ti 83 Plus back to life.

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 that anybody could make the same mistake. And of course, the calculator will never come on if the batteries aren't in correctly.

If your Ti 83 Plus turns on when you put the batteries back in you do not have to re-install the OS. I just think it is better since, your OS might be corrupt.

The process below should reset your calculator.

1). Pressing the [2nd] key followed by pressing and releasing the [Up Arrow] key. This adjust the contrast in case the contrast was to low. Keep repeating if necessary for about 10 seconds and, then go to the next step. If calculator comes on and responds to key functions your done. Once again, if your calculator turns on after this procedure you do not have to re-install the new OS. You can quit these procedures now with a perfectly good calculator.

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

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". Connect to other Ti 83 Plus and, install OS from that calculator. Or, follow the instructions, I gave at the other posting "Connection Instructions" to reinstall the calculator operating system and, connect the computer and, calculator. You can start where, I say, "Link your computer and, Ti 84 Plus (Your's is a Ti 83 Plus) with the proper cable (USB or Black Link). Upon completion your Ti 83 Plus will be ready to use and, the new OS installed.

48GX has been idle for 4 years.Wont turn on. Is there an internal battery that I can replace?


The 48GX runs on three AAA type alkaline batteries. However, if the device was unused that long, the button cells used for backing up the RAM cards may also be depleted, and the calculator will report "low battery" displaying the ((.)) symbol, even with fresh AAA cells installed.

The RAM card mounted batteries are type CR2016.

Main batteries:
  • Remove the calculator battery compartment door by pressing down and sliding it off away from the calculator.
  • Turn the calculator and shake the batteries out.
  • Replace with a fresh set of AAA alkaline batteries. Polarity is marked on the bottom of the battery compartment.
  • Replace the battery compartment door by sliding it back in place.
RAM card batteries:
  • Turn the calculator over and remove the plastic cover over the plug-in card ports (display-end of the calculator).
  • HP recommends to turn on the calculator while replacing the RAM card battery to avoid memory loss. I assume, your HP48GX has no marbles to recover by now anyway, so it does not matter, I guess.
  • Near the left side of the end of the card. you'll find the nail grip in the black plastic battery holder. Use a thumbnail to gently pull out the battery holder. There is one battery in each card (additional cards are options).
  • Remove the old battery from the holder and replace by a new CR2016 button cell. The "+" side of the battery should point into direction of the calculator's front.
  • Re-insert the holder with the new battery and check the RAM card is properly seated still.
  • Close the compartment by sliding back in the cover.

How do you get it apart, to replace the battery?


To replace the battery on a TI-30XA, you'll need a Phillips screwdriver with a small head.

First, take off the cover and turn the calculator over so you're looking at the back. Then take out the screws that are holding the back of the case on, and place them somewhere safe.

You should now be able to see the old batteries; remove them and dispose of them properly. There is a diagram on the inside of the case showing how to install the new batteries -- put them in according to the diagram. Then reattach the case and screw it back on.

Turn the calculator over so you're looking at the front side, then press OFF, then ON/C, then ON/C again. Verify that the calculator turns on and everything works okay.

TI BA II battery change How do I do this without ruining the calculator!


Turn off the calculator and turn it over with the back facing you. Using a small Phillips screwdriver, remove the four screws from the back cover. Carefully pry off the back cover. Using a small Phillips screwdriver, remove the screws from the metal battery cover and lift the cover off the battery. Tip the calculator slightly to remove the battery. Caution: Avoid contact with other calculator components. Install the new battery with the positive sign (+) sign down (not showing). Replace the battery cover and the screws that hold it in place. Align the screw holes in the back cover with those in the calculator, then snap the back cover onto the calculator. Replace the screws.

The battery is a CR2032.

Wont turn on when new batteries were installed


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

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.

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.

Wont reinstall OS (error message during installation)


I had a very similar problem when trying to install the new OS. The way I got it working was

1. make sure you have fresh batteries in.
2. Find a new computer which you have not used neither TI connect nor the calculator on.
3. Download the OS to this computer from Ti´s webpage
4. Install Ti connect and the calculator on this machine 100 % correct! (check other help files for this)
5. Go into Ti connect, and it should find the calculator now.
6. Use the "device explorer" and then the "OS downloader" directing the downloader to the path where you have already downloaded the OS to the computer.

I hope this helps you out...
