SOURCE: The buttons on my calculator will not work

Hello,
Back to the original problem. Would it not be a good idea to have the calculator repaired, if cost of repairs is significantly less than the price of a new one? But then, what do I know?

SOURCE: I want to calculate powers on my calculator but am

You have two buttons to calculate powers: The [x^2] calculates the square of a number while the [caret ^] key allows you to calculate any power, be it with integer, fraction or negative exponent.
Both keys are next to one another, one below OPTN and the other below the VARS key.
To calculate roots, you have the square root [SHIFT][x^2] the xroot key [SHIFT] [caret ^] , the CUBE root [SHIFT] [(] , and the inverse key [SHIFT][).

Ti-36x Solar Scientific Calculator issue: number buttons resetting to zero...


Look in the back of the calculator, some TI models have a pin hole to hard reset the calculator.

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.

The buttons on my casio fx-9750g plus arent working


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.

My TI-84 Plus calculator won't work. It won't switch off by itself. When the batteries are reinserted, it says that all RAM has been cleared. When i press the 'ON' button again, the screen clears. but...


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.

My Ti83 silver edition will not turn on.


I'm not sure if this will help you patchesb7; it sounds like your calculator is having issues :(
This will help others whose calculators suddenly won't turn on anymore, even after changing the batteries.

Note:
This will return the calculator to the way it was when you got it out of the package. Any data or programs have stored since will be lost.

Step 1: Remove all four AAA batteries.

Note: You will have to hold down the CLEAR button while doing Steps 2 and 3. Do not let go until after you have pushed ON in Step 3. I found this easiest to do by holding the calculator upside in my left hand with my pointer finger holding the CLEAR button so the ON button was easier to access.

Step 2: Hold down the CLEAR button (located under the arrow keys) and reinstall the AAA batteries.

Step 3: Press ON button and then let go of both buttons. The screen should say the RAM has been cleared. Press CLEAR to continue.

None of my buttons work except the ON button


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.
