TI 84 plus silver edition wont turn on


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.

You can try to take out the aaa's and leave it sit for a minute or so. If that fails you can try to take out all the batteries (including the back up battery) and leave it sit. If that still doesn't work, then you can try calling TI-cares (800-842-2737), I hope this helps

Have you tried to reset the calculator?

From page 671 of the TI-84 Guidebook:

To reset the calculator:
1) Remove all AAA batteries
2) Hold down the On button for 10 seconds
3) Reinsert AAA batteries
4) Turn the calculator back on.

Note: When you reset your graphing calculator, the contrast sometimes changes.
