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.

My calculator ti-84 plus is having problems. When i turn it on it will turn off quickly by itself. and while its on i try to click on any botton and it doesnt show the number etc


It could be that the main batteries are drained and are no longer able to supply power to the calculator. Replace the AA batteries with a fresh set. After replacing the batteries the display may become too dark or too dim. To set the correct contrast
Press [2nd] key and release it.
Press and maintain pressure on UpArrow to increase contrast (darken screen), OR on DownArrow to decrease it (lighten screen). If you overshoot your intented contrast you can revert the processs.

If Texas Instruments TI-84 Plus Calculator hangs on screen "RAM CLEARED" , what should I do?


You should try a few different things:

1) Press the Clear button
2) Press the On Button
3) Remove and replace the batteries

If the final step does not work, you should also remove the backup battery. This is located UNDER the AA batteries. You will need a small screwdriver to remove the cover. Replace everything and turn the calculator back on.

Replaced AA batteries, but still will not turn on


I sure hope you meant AAA batteries :-)

TI calculators have an annoying habit of losing screen contrast when batteries are changed. Turn the calculator on. Press and release the 2ND key. Press and hold the Up-arrow key for five seconds or so and see if the screen becomes legible.

Battery change tI - 84


TI calculators have an unpleasant habit of losing screen contrast whenever batteries are replaced, so that the blank screen looks exactly like it's off.

Turn the calculator on (though you won't necessarily see anything). Press and release the 2ND key. Press and hold the Up-arrow key for five seconds or so.

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.

Yes there is, but you need a screwdriver to get at it... make sure the batteries are in the right way first, though.
