TI-84 Plus CE: Is er logfile (geheugen/geschiedenis) in het toestel?

Wed, 12 Jun 2024 09:18:29 -0700

Kan ik zien wanneer (datum /tijdstip) wanneer er de laatste keer alles gewist is? Ik ben dus opzoek naar de geschiedenis van het toestel. Is dit mogelijk? Zo ja, hoe kan ik dit nakijken?

Can I see when (date /time) when everything was last deleted? So I am looking for the history of the device. Is this possible? If yes, how can I check this?

TI-84 Plus CE: Knoppen GR werken soms niet en hij gaat soms plots aan

Sat, 01 Jun 2019 05:21:04 -0700

Sinds een paar dagen geleden doet mijn GR plotseling een beetje vreemd. Nouja plotseling, dat weet ik niet helemaal zeker. Het zou zo kunnen zijn dat er een beetje water bij is gekomen dat aan mijn brooddoos zat nadat ik hem had afgewassen. Maar dan heb ik het ook echt maar over een heel klein beetje water en de klep zat tijdens dit gebeure wel op mijn GR.

Het probleem : soms stoppen de knoppen van mijn GR heel even of voor een langere tijd met werken. En de GR gaat soms plotseling aan zonder dat ik er iets mee doe.

TI-84 Plus CE: TI-84 Plus CE - ON Button Not Working To Turn On or Off

Sat, 01 Aug 2026 15:29:39 -0700

The ON keypad button does nothing, but everything else works fine. I can only turn on the calculator in 3 ways:

Remove and reinsert the battery which also clears the RAM.
Press the tiny reset button in the back which also clears the RAM.
Plug in the charging cable while connected to a charger which does not clear the RAM.

When it’s on, I can’t turn it off. Pressing 2nd - ON does nothing. If I leave it alone, it will power off after about 3 minutes of idle time when unplugged and about 15 minutes when connected to a charger. When it's off, pressing the ON button does nothing and I have to use one of the 3 methods above to turn it back on.

I tried everything in "TI-84 Plus CE Recovery Techniques" including reinstalling the OS, but the problem is exactly the same which leads me to believe it’s a hardware problem, so I disassembled it and removed the PCB board, finding some traces of corrosion on the PCB board by the ON switch contact and on the rubber actuator. I cleaned them with alcohol and reinstalled the OS again just in case. I also installed a brand new battery, but after all of that, the symptoms are the same. Any ideas about how to fix this would be greatly appreciated.

Texas Instruments TI-83 Plus: Spare Battery Severely Leaking/Calculator Won't turn on

Sun, 12 Jul 2026 00:03:39 -0700

So, i recently opened up the spare battery compartment of my TI-83 Plus, and noticed one of the spare batteries was slightly bulging. i decided to take it out to examine it. during this process, i had placed 4 new AAA batteries inside of it. (it didn't power on even when new batteries were inserted) When attempting to pry the Button cell battery out, i heard a faint hissing noise. i decided to remove the AAA batteries as a precaution. when i took the button cell out, it was severely corroded. (explains the mystery battery fluid that was appearing in the calculator some months back) i checked the other button cell out of curiosity, (i have an oddball unit that uses 2 LR44 button cells) and it was hardly corroded. there appears to be heavy corrosion on the spring. i was wondering if the calculator could be saved, and what methods i can use to help fix it.

TI-84 Plus CE: My Calculator won’t turn on or charge

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 Instruments Calculators: TI-5660 calculator stopped printing and displays error message

Sat, 06 Jun 2026 03:25:55 -0700

Hi everyone,

I was doing some calculations on my TI 5660 and mid calculation, the printer stopped, it displays an error (E and 0). I checked to see if the paper got jammed, or if the ink ribbon is stuck and both move freely. When I tried to reset the error, the printer makes a buzzing noise and the error is not cleared. Does anyone have any ideas how to fix this? Thanks in advance.

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

Mon, 01 Jun 2026 00:57:46 -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

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.
