    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. Does it?

    Take out all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Does the calculator turn on now? (You may have to adjust the screen contrast as described earlier.)

Having gone two months without a response to my second query, I assume my suggested reset solved the problem.

My ti 84 plus does not want to turn on, i thought it was battery problem so, i bought new batteries but i stil have a blank screen.


Could it be that your screen has been dimmed in error. Turn the calculator on & press the 2nd key and then the up arrow. This darkens the screen.

If this doesn't work, try taking out the backup battery. It is located in the battery compartment, behind a little door that you must take off with a phillips screwdriver. Leave it out for about 10 hours. If this doesn't work, try replacing the backup battery.

Hope this helps.

Try resetting the calculator to what I will call the "factory settings", do so by holding the "CLEAR" button, and while holding it, take out the batteries, then put them in
