TI-84 Plus CE: TI-84 Plus CE repeatedly turning on and off when charging.

Tue, 05 May 2026 10:24:16 -0700

My TI-84 Plus CE will repeatedly turn on and off repeatedly in about 1 second intervals while connected to the charging cable, regardless of the power source its connected to (wall outlet, laptop, power brick etc.). It will not turn on at all if not plugged in. I've tried pressing the reset button to no avail. The cable is essentially brand new. This also happened while it should have been at full charge, though it had been about 2 months since it was last fully charged, but it wasn't used in that time until I tried to turn it on recently. I tried taking the battery out and putting back in, and that didn't make a difference either.

TI-84 Plus CE: My calculator is not charging or turning on

Tue, 05 May 2026 05:17:27 -0700

Hi, I just got my calculator (TI-84 plus CE) in the mail and it wasn’t turning on so I plugged it in using the USB cable provided that says it’s for “data transfer and convenient charging”. I am worried because the screen is flashing with a message that says “calculator will restart when validation is complete” so it doesn’t seem to be charging. It’s still not turning on and I have no idea what to do, please help. (This calculator doesn’t have a light on the side so I am unable to see if it is charging or what the battery percentage looks like)

TI-84 Plus CE: How can I fix my flashing screen (TI-84+CE)

Mon, 04 May 2026 16:15:47 -0700

My calculator seems to have decided to no longer likes me, and is having startup issues.

It is stuck on a flickering white screen. I can’t turn it off. It doesn’t seem to be turning off on its own. I’d prefer to not have to completely wait for it to drain considering that I just finished charging it yesterday. The calculator does not seem to fully load at all and does not appear in the TI Connect CE program when plugged in to the computer. This is my personal calculator and I’d really like to have it fully working again, and if possible, salvage the programs I have on it. Is there anything I can do, short of buying a new calculator? Or is there a factory reset feature available anywhere I can use?

TI-84 Plus CE: Why won't my Ti84 Plus CE turn on?

Mon, 04 May 2026 16:04:07 -0700

My calculator will not turn on despite being at full battery (when it charges it has a green light). The screen does not turn on when I press the on button, instead it stays black. I have even bought a replacement battery online, but this did not seem to help. Before, my calculator would often not turn from time to time, but still turned on occasionally, and it always turned on after a few seconds of charging it, but now it does not.

Texas Instruments TI-30X IIS: Automatically adds a digit to the end of my entry

Wed, 22 Apr 2026 13:20:25 -0700

My calculator automatically adds a 9 to my last number every time I try to do math. For example, I type 5 + 6 and expect =11, but calculator does 5 + 69 and I get =74 :(

The 9 button does not appear to be sticky.

The device turns off while typing and won't turn on unless I reset, clearing out the work. It still calculates after I try a few times but I lose a lot of time typing it in over and over again.

Mon, 08 Dec 2025 09:20:40 -0700

Hello! My TI-84Plus CE just completely died the other day. We tried to charge it and it shows now signs that it is charging. The screen doesn’t light up or show anything. We tried replacing the battery, and still the calculator shows no signs of turning on.

Is there anything else that we can trouble shoot?

Texas Insturments TI-84 Plus Color Silver Edition: "Waiting... Please Install Operating System Now"

Sun, 19 Oct 2025 19:04:24 -0700

My calculator says "Waiting... Please Install Operating System Now", and when pressing any button it says “Error! Press any key to turn unit off. Then turn unit back on”, then the process just repeats itself. I have tried to restart the calculator but it did not work. I also tried to download an OS from the TI website from my Mac to the calculator but it also did not work. I believe it said something along the lines of it wouldn’t download the operating system to the calculator because the calculator didn’t have OS, which was kinda the whole point of trying to download it! I also could have done it wrong though, so any help would be appreciated on how to get my calculator working again.

Texas Instruments TI-82: Please Help, It won't turn on no matter what I do!

Ok, so I recently got my old TI-82 out of my junk drawer to use again.I replaced all of the batteries and checked for corrosion, but it just wont boot. No matter what I try the thing will not turn on at all. One thing to mention is that it has been sitting for over a decade. I'm not sure if that's a factor.
