Buttons My calculator turns on but thats about it. It wont turn off and none of the buttons work i have to take out tha batteries to turn it off how do i fix this problem?

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.

I also hope you let the calculator dry out thoroughly before replacing the batteries.

when the calc is on do you see the cursor blink if it blink and no button works check maybe one of the buttons stuck if it does not blink its an hardware problem

Reset the calculator by taking out all of the batteries, then hold down the power button for 30 seconds. Replace the batteries and see if it works again. If not, remove all of the batteries again, this time include the backup battery (you'll need a small phillips screwdriver). Wait 5 minutes and reinstall the batteries. Hope it works for you. g.

Will the calculator turn on at all? If not, check the batteries first. There is a little coin battery that stores memory for the device behind where the regular batteries sit. This does not often fail, but could cause the thing to not power up. Note: removing the coin battery will clear any information stored on your calculator.

If the device is stuck in an infinite loop, or is unresponsive with the busy icon, try pressing and holding the "2nd", left, right and "on" buttons in that order and holding them all at the same time. This is the command to cancel whatever process the device is working and clear the internal memory (At least on the TI-89. I'm not 100% sure the command works on an 84).

Having gone over a month without a response to my query, I assume my suggestions solved the problem.

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

A simple procedure THAT MAY REVIVE the calculator is to reset the calculator by pressing the RESET button on the back. Use a straightened paper clip to press the recessed button.

The Ram cleared message is normal after you change batteries. When you see this message you press the CLEAR button to erase it. You do not press the ON button again because the calculator is already ON. If you want to turn calculator OFF you press [2nd][ON] (OFF).

On certain calculators, pressing the ON button when calculator is already ON is interpreted as INTERRUPT the current command.

clear ram

Sounds like a possible short to me, But I don't have experience with that cause I have yet to test my calc with water if you know what I mean... The one thing that I can suggest is trying to connect with another persons calc and try the "send OS" command to see if that will reset your calc to a working state. Sorry to hear about the damage though.
