Changing faceplate on ti-84 i understand it can't be done but has anybody actually tried

Transferring data and programs to the calculator requires a lot of energy that almost dead batteries cannot provide. Change batteries and try the transfer again using TI Connect. To transfer from a similar calculator the receiving one must be in RCV (receive mode).

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.


What do you mean by "changed the resolution"?

If this doesn't do it, please reply to this post and we'll go on to the next step.

Yes, you can change the faceplate of the TI 84PLUS Silver Edition only, not the TI 84 Plus. Face plates are available for purchase at the TI online store.When you go the online store, select the country, then the calculator model. You will find them under accessories for the TI 84 Plus SE.

If I'm understanding you correctly, you want to graph something like

5x+3=9

If this is correct, graph 5x+3 in the y1 line and 9 in the y2 line. To find the solution, you will press 2nd, then trace the intersection and hit enter 3 times. This will get the solution you need for the equation.

If this is not what you are wanting to do, you need to be try again and elaborate more.

Hi
This is a common problem with the TI 84 series
It will cost more to fix then buy a new unit
Sorry i could not help

you can't only on the TI-84 plus silver i found that out the hard way :P

Ask here for the TI-84 manual, they will get it for you.

Look at the bottom of ur calculator. not the back the bottem. and u should see where the gray area meets the white area. There should be a small lip at the bottom of the calculator. Pull back the lip, it should come off with minimal force. That is how u remove the faceplate

this a simple misunderstanding of calculator lingo. When u enter the -2 the calculator is actually doing -1 x 2 according to order of operations the exponent will be done first then the -1 multiplied. So to stop this from happening u must do on ur calculator (-2)^2 = 4
