    Try a hard reset if you're willing to clear all RAM.

    Remove all four AAA batteries. Press and hold down the ON button for at least ten seconds. Replace the batteries. Turn the calculator on. Does it work now?

Having received no response in over a month, I assume this is no longer a problem.

My calculator won't turn on the batteries are fresh plz help

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?

Calculator turns on, but cannot turn off and no other buttons work.

If the TI-84 does not function even though you are sure that the
batteries are fresh, you can try manually resetting it by following steps:

1. Remove all of the AAA batteries from the graphing handheld

2. Press and hold the ON key for ten seconds

3. Replace the batteries

4. Turn on the unit

When you reset your graphing handheld, the contrast sometimes
changes. If the screen is faded or blank, adjust the contrast by
pressing 2nd and releasing up-arrow or down-arrow keys.

A friend gave me a TI-86 graphing Calc. I wont turn on!!!

maybe try changing the small memory battery inside, I think its a cr1616 or cr1620. If this doesn't work use it as a paperweight.

Only the on button and shade of screen works

Sorry to hear that you all are having problems with your calculators. I don't think that resetting the units will help. You should contact TI.
