    I tried that but it isn't helping... my screen is still empty ( not black) and it doesn't react at anything. Even if I try to close the calculator it doesn't do anything..

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, please reply to this post and we'll go on from there.

Why is my calculator frozen?


Is the cursor checkered? If so, there is no more space on the entry line. Use the DEL key to shorten it or clear it. Clear the RAM also.

My TI-84 cursor will not allow me to type anything


If the cursor is not allowing you to type anything that means either the calculator available memory is full or that you have exceeded the number of characters in a single command.
Clear calculator memory or just clear all entries (history) or split a complicated command into multiple shorter commands.

My TI-84 calculator isn't working. When I press the "ON" button, sometimes it would respond, but most of the time it doesn't. The screen just remains blank. I've changed my batteries...


try taking out the triple A batteries and leaving the calculator to sit with them out for a minute or so, replace them and check if it's fixed. If that doesn't work you can do the same, but take out the small button back up battery as well. If you're still not having luck you should call ti cares (800-842-2737) they're usually helpful.

My ti-84 calculator wont react to anything and it says garbage collecting. i think the bar on the side should move and its not moving and its been like this for several weeks. i did download a whole pile...


I remember this happening once to my TI-83. I know it's a different calculator. But it happened frequently. Without completely reconfiguring the calculator, you can remove the batteries whenever you see the message and when you start it up again, it should be okay. It may continue to display this message once in a while. I used to just remove the batteries. I don't know if it will work on your TI-84 the way it worked on my TI-83, but I hope this helped!

My calculator is completely non responsive. When I hit the on button, the calculator cursor comes up but does not blink or allow me to type anything in. I have to hold the on button to keep the cursor...


It sounds as if the batteries are dead. If you are having to hold the power button on to keep the cursor on the screen, that is because the batteries only have enough power to flash a cursor, holding the power key means that the flash is constant. Try changing the batteries, this should solve the problem.

its possible that the batteries leaked inside and cause some problem.

Have you tried to reset the calculator?

From page 671 of the TI-84 Guidebook:

To reset the calculator:
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.

TI 84 plus calculator, flashing dot in upper left hand corner


Hello,

When you turn the calculator on, its screen is cleared, save for a small square on the top left corner. This is the cursor and it is blinking: The calculator is waiting for you to order it to perform some calculation.

Try this simple operation
[1] [+] [1] [ENTER]. The calculator will display the result one line down justified to the right.

Hope it helps.
