Question about Office Equipment & Supplies

Open Question


I'm trying to find someone to help me re-set my calculator from TI. I know it's an older model, but it still works just fine up til now. For some reason, it prints out different amounts than what is entered and now a diamond shape appears on the right side of the amt. Window shows the amt. and whatever step is being done. Print-out shows nothing to compare with the window display.
I would appreciate any advice if possible to e-mail how to correct the problem. I think I might have accidentally put my hand on the memory keys as I was re-adjusting the pulley belt that had slipped off.

Try removing the batteries in addition to reseting the calculator.

Just reset mine and is current. If the built in battery needs changed, access panel is on the back. It uses a watch type battery.

Ti nspire calculator. calculator will not turn on. installed new batteries, calculator only 2 years old with moderate use by daughter for school. ti cares sent me a link on troubleshooting, methods did not...

I have fixed several TI calculators for a school that had loose or corroded battery contacts. Cleaning the contacts and bending them a bit to get a good grip on the batteries got them going. You can try this on yours and see if you have any luck. Also try another set of batteries on the off chance one of the new ones you installed is bad (it does happen, and isn't one of the first things you'd think to check) or use a battery tester. If the batteries are good and the calculator still doesn't work, something inside has failed. Either go for the refurb or (if that specific model isn't required for school) see what similar brands and models are available. There might be something suitable for less than the TI price.

How to do nPr or nCr on TI-30x Solar (scientific calc.)

If you have an older version on the TI30x Solar (not TI30Xa or newer) then you must use a different key sequence for nPr/nCr.

52 [2nd][x/y] 5 [2nd][nCr] gives 2598960 (the x/y button is above the Pi symbol on my version).
8 [2nd][x/y] 3 [2nd][nPr] gives 336

This took me forever to find out, so hopefully it will help someone!

While you are waiting for the eventual arrival of your new calculator, we may try to diagnose the ailing of the old one.
  1. Remove the old batteries. Buy a new set of batteries.
  2. Prepare the connectivity cables needed to connect the calculator to the computer. Choices are the TI USB silver cable, or the TI Graphlink Black serial cable.
  3. From, download the connectivity software compatible with the cable you will be using from this site. In all probability you will need the TI Connect 1.6 for Windows or Mac.
  4. From, download the latest operating system
  5. Install the Ti connectivity software on your computer.
  6. Wait for a day then insert the new batteries.
  7. Turn calculator ON
  8. Execute the TI Connect software.
  9. Connect calculator to computer.
  10. If you have an active Internet connection, click the Updates button on TIConnect main window.
  11. The software will download the latest OS and install it on the calculator.
  12. If you do not have an active Internet connection, run the TIConnect software.
  13. Connect calculator and computer. Turn calculator ON
  14. Drag and drop the OS which you downloaded on the TIConnect main window.
  15. The software will attempt to install the OS,
If for some reason this does not work, you can transfer the OS of a working calculator. You will need a cal-to-calc USB miniA to miniB cable or a calc-to-cal I/O cable.

Ti 84 not working

Since it gets tossed around a lot, it is possible though improbable that the batteries lose contacts with the electrical terminals.
You may try to darken the screen a bit.
1. Press [2nd] key and release it
2. Press [UpArrow] and release it.
3. Repeat steps 1 and 2 in sequence until contrast is satisfactory.

If that does not fix the problem, use a calc-to-calc cable and try sending something to it from a working calculator.

You can also download the TIConnect software from and install it on your computer. Then connect the calculator to the computer by means of a USB cable, a TISilverCable, or a TI Graphlink (Black cable). Turn the calculator ON, run TIConnect, connect calc-to-computer and Click TIDEVICEINFO in TIconnect main window.

If it tells you NOT FOUND, on any of the ports, click the communication settings: Set the device type to you calculator model. Set the cable type. Set the port (COM x) or USB1
If calculator is not detected through any of the available ports (COM ports, or USB), then it would suggest that calculator is in need of repairs.

Hope it helps.

Ti-84 plus

this might seem weird.... but have you checked the brightness of your calculator? if someone was playing with it and set the brightness to 0 it wont seem like there is anything. if u press second then hold the up arrow key it will make the screen darker. I dont know if this will help you or not but i know some of my friends like to play pranks where they set the brightness really high.

kinda. The TI-85 programs differently, lacks a table feature, is not upgradable, has redefinable keys, has a larger screen, is smaller, energy efficient, TI-86 semi-compatible, and is older.
The TI-84+ has archive memory, flash-upgradable, FSTN (clearer) screen, 16*8 screen, USB On-The-Go compliant, almost a centimeter longer, assembly language support, and a tad bit faster.

TI-82: $89
TI-83 Plus: $79-99
Free TI-85: $0
TI-84 plus: $119.99
TI-84+SE: $129-139
TI-89 Titanium: $149

TI 84 plus

I had the same problem. Found a posting on Youtub of someone messing up their TI-84 for fun by sticking a paper clip in it... One on the comments noted that dust in the data port can also cause it to not work right. I did not see anything dirt or dust on/in my TI-84. But I went ahead and took a can of compressed air and blasted the data port. Problem solved, it's been working fine ever since... If you have a receipt, and it's less than a year... TI replaces for free... other wise it cost $55 + $6 for shiping... 1-972-917-8324 is their number... Why it's not an 1-800.... I don't know... Hope this helps
