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: 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?

Hello. I have a TI 84 Plus CE that has just been sitting in my backpack for the last couple of months (in hindsight wasn’t my best idea.) I took it out of my pack one day and found out the screen was cracked (pic below.) Is there any guide to fix it? The panel itself is not broken but the glass separating them is. Thanks!

TI-84 Plus CE: Why my charging light is always on? It kills the battery.

Fri, 19 Nov 2021 08:49:10 -0700

Last night after I unplugged my calculator, I found out the charging light was still on and it couldn't be turned off. The light is on all day today, and it really kills the battery, so by the end of today I have to recharge it . I tried to reset and remove the battery, but these methods didn't help. So I wonder what is wrong with my calc, should I get a new one or should i just get a new battery? Is there anyway i can do to save it? Help S.O.S. Thank you!

update: Thanks for all the help.

I changed to a new battery and updated my OS, but the charging light is still on and it really kills the battery life. Usually the ti-calculator can stand for at least 2 weeks, now I have to charge it every 12 hours. I would really like to know is there another way to fix it? Thanks!

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

Tue, 21 Jan 2020 02:24:19 -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.

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

Mon, 14 Oct 2019 19:03:55 -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?
