    I have the same exact problem. It's slow and unresponsive, and to get anything to work I have to push the button down for a couple seconds to make anything show up. Sometimes it even freezes.

    I have the same problem. When I hold down the clear button for a few seconds and press the over arrows it will clear and then I just reset it by pressing 2nd + 712 this clears the memory and it will only work for a little bit until you have to do it again...

If a piece foreign material such as a pencil lead is lodged in the I/O port of the calculator, it may create a short causing the calculator to respond slowly to key press entries.
If the piece of conductive material can be removed, it may restore the calculator to normal operating condition.

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.

None of the buttons on the TI-84 calculator work

Having gone five months without a response, I assume the reset solved the problem.

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.

Frozen ti 84 plus silver edition

Ther is no reset button. You have to take the batteries out.

Take the AAA batteries out and take the back up battery out...located in a little door with a screw just above the AAA batteries. Leave the batteries out for about 8 hours. This is how you reset a TI graphing calculator.

I don't even know!

What i think is that your calculator has water damage. It is not dead. There still is hope. The slow response is due may be due to a short in your I/O port. Blow really hard in there that might stop the slow response. Other than that let it sit without the batteries to dry. Then put the batteries back in and if that doesn't work its probably what spongeboob said and your going to need to ditch it.
