Question about Texas Instruments TI-34II Explorer Plus Calculator

TI-35 Plus I purchased the TI-35 Plus hand-held calculator years ago. I dropped it, the batteries popped out and now it won't turn on. I think it may be the battery contacts. Can it be repaired?

I agree - i used a bit of rubbing alcohol on the contacts and bent them inward a slight bit - had to twist the case a bit too but now it works wonderfully and i've had this calculator since it was first out on the market - love it!

Make sure the battery contacts are clean. I just fixed mine, as it had been sitting for some years and the batteries went bad.

I gently cleaned any "green mold" from the contacts with a light Scotch-Brite pad and some electrical contact spray that I got at a local hardware store.

I tested the batteries with my digital meter to make sure they were 1.5V or more and put everything back together. Works great!

Give it a whirl---this is a nice little calculator. I bought mine in 1990-1991 and it's gotten me through undergraduate and graduate school...

New batteries and won't turn on


You might want to check the batteries, and make sure that they're in the correct way. If they are, then you either purchased bad batteries, or your 83 suffered a catastrophic failure/broke

My TI-84 plus silver edition calculator is not responding. Whenever I press a button it takes forever to put it up on the screen or it doesn't work at all! I need some serious help with this. I tried...


Hi purzabumafu8,

You need to re-install the Ti 84 Plus OS on both calculators, ASAP!!! You can fix these problems by installing the newest Ti 84 Plus 2.55v. MP OS, operating system. Use fresh batteries.

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 USB or, IO link ports. Then they can send you a copy of their OS, while you receive it on your Ti 84 Plus. Hopefully, your friend will have Ti84 Plus 2.55v. MP OS on their calculator or, it might not work. Link the two calculator together through the USB or, IO link ports with the proper cable. If don't have another reliable calculator to connect too, you'll have to connect the calculator to a computer to download the OS, goto Procedure 5. If your downloading off another calculator goto Procedure 1.

Important Note: Never disconnect a TI Connectivity Cable during a transfer. Lost of power during installation of OS will destroy your calculator.

Procedure1. Procedure to linking to another calculator.
On their calculator press, [2nd][Link][G] [Right-Arrow]. On your calculator press, [2nd] [Link] [Right-Arrow] [Enter] and, then press [ENTER] on their calculator too. Their calculator should say, "TRANSMIT" and, your's will say "Receiving." Then on both calculators once transfer is complete press, [2nd][MODE] to quit and, return to the Home screen. If the OS was transferred then your finished with these procedures. If your calculator won't turn on or, is locked up try the Procedure 2, below.

Procedure 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". If calculator did not turn on or, is still locked up goto Procedure 3, unless already did Procedure 3, then goto Procedure 4. If you calculator does come on and is responding and, your connect to another calculator goto Procedure 1. If you calculator does come on and is responding and, your connect to a computer goto Procedure 7.


Procedure 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. Goto Procedure 2.


Procedure 4.

If the above process did not work. Try re-doing the Procedure 2, and, this time extend the time in Procedure 3, by 5 minutes to 10 minutes before you put all the batteries back in the calculator. These calculators can be a little stubborn at times so, keep trying Procedure 2.



Procedure 5.

If you can't find a calculator to connect too, you can connect your Ti 84 Plus to a computer that has Ti Connect software on it. If you need to connect your Ti 84 Plus to a computer make sure the Ti Connect software is operating properly. You do not want any hang-ups while installing the Ti 84 Plus OS.
Procedure 6. Procedure to installing the latest Ti84 Plus 2.55v. MP OS. TI OSDownloader does not always install the latest OS.
You can get the latest copy of Ti84 Plus 2.55v. MP OS and, guidebook by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 84 Plus 2.55v. MP OS!" Once your at the Ti site click the Download Item, "Ti84 Plus family operating system". Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti84 Plus family operating system will download to you.
Next, click "SAVE" and then a window to a folder will pop up. It is probably a window to a folder that you download too. If so, you may want to change it and, save to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 84 Plus guidebook too, if needed. If your calculator will not turn on or, is locked up goto Procedure 2. Or else goto Procedure 7.

Procedure 7.
Important Note: Never disconnect a TI Connectivity Cable during a transfer. Lost of power during installation of OS will destroy your calculator.
Link your computer and, Ti 84 Plus calculator with the USB cable or, Direct Black Link cable that came with the Ti 84 Plus calculator. Next, drag the Ti 84 Plus 2.55v MP OS that you saved earlier in "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Click, "Continue" when the "Erase Warning" pops up and, the new Ti 84 Plus 2.55v MP OS will begin to install. Next, the Ti Device window should pop up and, highlight the port when it finds what your Ti 84 Plus is using, USB1 cable or, Direct Black COM1.

When the Ti Device Explorer finds and, highlights your calculator's information click, "Select." Then click, "Yes" when the next window shows up with your calculator's information and, the OS will continue to download. Upon completion the newest Ti 84 Plus 2.55v. MP OS will be installed.
If you run into any trouble with software or, drivers just comment to what failed at this posting and, I'll be glad to help you.

My for the TI 84 Plus Silver Edition screen doesn't work. I changed he batteries including the back-up. The screen won't light up. I bought this calculator around 3 years ago.


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 that doesn't work, remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries.

If that doesn't fix it, please append a comment to this post and we'll go on from there.

Cant get Y values when i type in X values in table


Hi there,

Well first of all you can try to reset your calculator, just follow the below steps to know how to reset it -

1. Turn off your TI-83 Plus.
2. Open the battery panel on the back of the calculator and remove one of the AAA batteries. Keep this battery handy, as you'll need it again.
3. Press the "Clear" button, and keep it held down.
4. Put the battery back in and turn on the calculator, with the "Clear" button still held down. When the calculator's screen displays the message "RAM Cleared," release the "Clear" button.
5. Remove one of the calculator's batteries again. This time, hold down the "Del" key.
6. Reinsert the battery and turn on the calculator. Release the "Del" key when the screen reads "Waiting...Please install calculator software now."
7. Use the TI Connectivity cable to connect your calculator to your computer. Run the TI Connect software to reinstall the calculator's operating system. If you don't have an up-to-date copy of TI Connect, see Resources.
8. Turn off the calculator and disconnect the TI Connectivity cable. Remove the AAA batteries, as well as the small, circular lithium battery.
9. Wait five minutes before putting the batteries back in. Turn on your calculator.
Hope it helps ..........

Good Luck!!

Thanks

Cant install any applications


Hello,
Run the TI connect software on you computer. Turn the calculator on and connect it to a USB port on the computer. Before you drag and drop applications on the TI connect software window, Click on one of the icons (TI Device Explorer, TI Device Info, TI Screen Capture). Two new smaller windows pop up, the one on top has the title Select TI device. If in that window it recognizes your Calculator Model, you click on select and OK, and you are ready to communicate with it.

If on the other hand, it fails to find your calculator on any of the 3 or 4 communication ports (COM3, COM4, USB1, etc.) then you click on the communication setting and in the drop down lists
