Question about Texas Instruments TI-85 Calculator

Calculator won't power up.

I haven't used my ti-85 since college (almost 10 years now...wow I'm getting old). I couldn't get it to turn on, so i replaced all the AAAs and the back-up battery. I'm still getting nothing when I try to turn it on. My wife has a TI-83 that we use around the house frequently, so I'm not as totally clueless as you might expect. I've tried turning it on and darkening the screen using the 2nd function button and the up arrow key...nothing. One of the contact plates for the positive end of one of the AAAs is missing. There is still a metal spring/lead underneath where the plate should be. The battery contacts this spring/lead. Is that my problem? If so, do you have a suggestion for getting it fixed without having to send the calculator off to TI?

I've had my ti85 probably since highschool or college. I don't remember. I've used it within the past few months. The screen had been a bit dim, even after turning the contrast up. I figured it just needed new batteries. I put new batteries in today and the thing won't even turn on. Tried the reset and nothing.

Yes, I have a TI-85 that also will not turn on . I replaced the AAA batteries but did not replace the back-up battery. Any help getting this calculator to work would be appreciated.

Thank You

I'm having the same problem. The calculator was working Friday, but very dim. So I replaced the AAA batteries, and then the calculator wouldn't turn on. I just replaced the CR1616 and still nothing. I'm at a loss as to why it was working 2 days ago and now it's not. :(

That is perfectly normal, almost all of TIs graphics calculators have it.

This worked for me, you just take out the batteries and let it power down for a few mintues, and bam when you turn it on again, its fine.

Calculator has been in a drawer for 2 years and now my daughter needs to use it for college. We put in new batteries and tried some troubleshooting ideas and nothing worked. It is in perfect condition....

Having gone over a month without a response to my query, I assume the suggested contrast adjustment solved the problem.

Ti 85 wont turn on, batts good, tried to adj contrast , still nothing

Are you sure the batteries are in correctly? They alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. You tried adjusting the contrast. Just try adjusting upwards. Sometimes it takes a little for The Ti 85 to come on or adjust right. The Ti85 is an old calculator and, may not work any more. I had my Ti89 for almost 20 years so, they are pretty reliable. If nothing has worked take out all the batteries including the small one in the back. Texas Instruments say's " leave them out for 5 to 10 minutes." I had to leave mine out for over a 1/2 day to get it to work.

Here is the battery reset procedure for the Ti 85.

Try a new set of AAA batteries.

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.
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.
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.

Just keep trying. Sometimes they can be a pain.

I have not used my TI-85 in 8 years. Inow it will not turn on. I put in fresh batteries. I stored it without batteries in it.

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.

Calculator will not turn on. I have a texas instrument calculator TI85 that will not start. Any suggestions?

Hi,
The batteries may be depleted, and they need to be replaced. If abtteries are fresh and the calculator seems toi refuse to turn ON, the screen darkness must be increased before declaring that the calculator does not start. If screen is too light you won`t be able to see that calculator is already ON.

To increase the contrast.

Press the [2nd] and release it.
Press and HOLD the UpArrow key until you can see something on the screen.
The screen may have about 10 levels of darkness

Hope it helps.
Thank you for using FixYa and for rating this solutions.

I have not used my calculator (ti-85) in a couple years. It has been in storage. When I got it out and turned it on it worked. Just the numbers were very light. So I put in new batteries. Now when I turn...

Try adjusting the contrast. Press 2nd then down arrow, 2nd then down arrow over and over and you should see the screen get lighter and lighter.
