My TI-84 Plus calculator will not turn on. It is one year old, and seems like new, but won’t turn on. Any suggestions? I can’t find a reset button on it.

TI-84 Plus Silver Edition: Only 1 graph for 2 Inputs?

Thu, 05 Dec 2024 14:39:20 -0700

So I have two inputs put into my (Y=) values and both of the equal signs are "highlighted". Then when I go into the graph, only one equation shows up. Yes they are 2 different equations, one is a cubic and the other is a quadratic so they should look totally different. If I go to the table menu after viewing the graph, only 1 set of values appears and if I go back to the (Y=) menu, the Y2 equal sign isn't "highlighted" anymore either. Bottom line is that no matter what, only one equation shows up on the graph.

TI-84 Plus Silver Edition: Calculator pulses on and off, resetting ram and OS does nothing.

Sat, 02 Sep 2023 04:07:40 -0700

Here is what happens:

1) I pull out all batteries so the RAM can reset.

2) Put batteries back in and calculator starts working for about 30 seconds

3) Calculator shuts off by itself

4) Turn on, screen flashes real quick to display where I previously was, then shuts off.

5) #4 repeats until ram is reset again.

Things I have tried

-OS Reset

-RAM Reset

-Backup battery and battery replacements

-Cleaning connectors

I have another calculator I can sub out parts with.

Is it a capacitor or something I need to replace?

TI-84 Plus Silver Edition: My calculator shows ERR: INVALID when trying to calculate Y of graph

Mon, 31 Jul 2023 05:45:05 -0700

My calculator is a TI-84 Plus Pocket SE. Basically as the title says, let’s use Y=X graph as an example. If I have my window values of X set to Xmin = -10 and Xmax = 10, and I graph the function Y=X and use the “calc value” function to try to calculate for a x value beyond the X window values (for e.g x=11) I will get an ERR: INVALID.

Is it impossible to calculate y values for X that is beyond your currently set X window values? Or there is something wrong with my calculator settings and how do I correct it? Thanks alot.

TI-84 Plus Silver Edition: How to turn on newly bought TI-84 Plus Calculator?

Fri, 12 Mar 2021 09:20:47 -0700

My aunt recently bought me a new TI-84 Plus for college and after opening the package and inserting all of the batteries I can't seem to figure out how to turn the calculator on. I've tried simply pressing and holding the ON button & taking the batteries out and putting them back in. I've also hooked it up to the USB cable that came with it, but after 15 minutes of charging nothing seemed to happen. Am I doing something wrong or forgetting something? Do I just need to let it charge more or is there some software I need to download or something? Thanks to everyone in advance.
