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?

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.

Texas Instruments TI-Nspire CX: TI-Nspire CX Cas Damaged Charger Port

Tue, 07 Sep 2021 08:37:33 -0700

This question is specifically for the CX CAS model of the TI-Nspire calculators.

The calculator is fully functioning except for the fact that it won't charge, unless the cord and charging port are aligned a certain way. It is not a problem with the cord, but with the charging port.

It seems that its contact points to the motherboard have been disconnected, as it has come loose and moves independently of the chassis, and only with luck can it be placed a certain way so that the calculator may charge. I would have to open it up and solder the contact points back to the motherboard, but I don't have the tools nor the know-how to do it.

I tried looking for ways to just charge the battery itself, since it can be easily removed with a Phillips screw driver, but haven't found the parts that would fit just yet. Any way to be able to charge it up would be appreciated.

TI-84 Plus Silver Edition: How do I fix the screen on my calculator?

Sat, 15 Oct 2016 14:56:32 -0700

A small table was placed heavily on the screen and now there is a small mark on the screen that is light in the middle and dark in the surroundings. When I type in a number, I can faintly see through this mark, but it gets a bit frustrating, and I begin Calculus next semester. I cannot afford a new calculator and this one is functioning very well. This screen problem is a nuisance!

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!
