Question about Texas Instruments TI-83 Plus Calculator
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.
If that doesn't do it, remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. The calculator should come on (you may have to adjust the contrast as described earlier).
