    Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Does that do anything?

Having gone a month without any response to my query, I assume the suggested reset solved the problem.

My TI-81 has completely stopped working. I have put in new AAA batteries along with a new CR1620 battery. Any suggestions?


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 this doesn't do it, please append a comment to this post and we'll go on from there.

I have an older 1995 TI-82 that suddenly will not turn on. I changed the batteries including the watch battery and still nothing. Is there a reset or do you have a suggestion?


The following are 4 different things you can try that is on the Texas Instruments Website: " 1. Try a new set of AAA batteries. 2. Adjust the contrast by pressing and releasing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. To adjust or lighten the display, use the down arrow. 3. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the AAA battery and then turn the calculator on. 4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. "

Put new batteries but it wont turn on... it was working before it ran out of batteries about 2 months ago..


Could be the screen has been dimmed so much that you can't tell that it's coming on. Press on and then 2nd button and the up arrow key. You may need to keep pressing 2nd and up arrow key. This is how you darken the screen. You can also lighten the screen which may be the problem you have by pressing 2nd and then the down arrow key.

If this doesn't work, take out the internal battery that is located in a tiny door with a screw right above the 4 AAA batteries. Leave this out for about 8 hours and put it back in. Put in the AAA batteries and the calculator will be reset and may work.

Press 2nd then press the arrow up. Do it like ten times because it gets darker. For example...2nd arrow up, 2nd arrow up, 2nd arrow up, 2nd arrow up, and 2nd arrow up. If u press 2nd and the arrow down, it gets lighter. Try it. d[^_^]b

Black screen


Try 2nd Down Arrow. Your contrast may be turned up too high. This can appear to happen with new batteries.
