BATTERIES, Tim.

Batteries. Batteries. Batteries.

That is the description of what happens to TI Graphing Calculators when the battery power diminishes. The calculator will always reduce its display contrast in order to maximize time till expiration. There should have been prompts to warn you of its impending doom.

So, if it was very dim one day, and failed to display another day; then it most likely lost its battery power.

**REPLACE THE BATTERIES**.

By the way, your calculator has lost all of its memory when it completely diminishes. So, if you want to avoid losing all of your content then I would suggest your**replace the batteries** __before__ battery expiration.

The screen may be too dim to read. Try pressing 2ND->Up arrow key repeatedly while the calculator is turned on and it may darken the screen enough so you can read it.

The screen may be too dim to read. Sometimes when the batteries are low, the screen automatically dims itself. The problem is, it doesn't undo that when the batteries are replaced. Try pressing 2ND->Up arrow key repeatedly while the calculator is turned on and the screen should start to darken so that you can read it.

TI calculators have an annoying habit of dimming the screen when the batteries are changed. 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.

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

Here is copy of the answer I posted to a question on how to use Matrices. Read it carefully. It helped a few people, and there is no reason why it should not help you too. If after a bona fide effort to understand it you still have a problem, post a comment here. What I am saying, is do not just shoot the answer, try it first.

First you must set Matrix calculation

[MODE][6:Matrix].

First you must set Matrix calculation

[MODE][6:Matrix].

- Then By entering one of the numbers [1:MatA] or [2:MatB] or [3:MatC] you get to choose the dimensions of the matrix (mxn)
- Once finished entering the matrix you clear the screen.

- [1:Dim] to change the dimension of a matrix (in fact redefining the matrix)
- [2:Data] enter values in a matrix
- [3:MatA] access Matrix A
- [4:Matb] access Matrix B
- [5:MatC] access matrix C
- [6:MatAns] access the Answer Matrix (the last matrix calculated)
- [7:det] Calculate the determinant of a matrix already defined
- [8:Trn] The transpose of a matrix already defined

- To add matrices: MatA+MatB
- To subtract: MatA-Matb
- To multiply: MatAxMatB
- To raise a matrix to a power 2 [x2], cube [x3]
- To obtain inverse of MatA already defined MatA[x-1] where [x-1] is the x to the power -1 key

One possible solution is to dim the screen contrast. To do this, turn the calculator on press the 2nd key, then the up arrow. If contrast has been darkened, this should work. To darken the screen if you get it too light, you do the same, but use the down arrow. Hope this helps.

Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow.
