Question about Texas Instruments TI-89 Calculator

1 Answer

My TI-89 was in my wife's purse, and got soaked in beer (don't ask). After letting it thorougly dry, it powered up no problem (although it still smells like beer). After powering it on, I noticed that the entire bottom row of keys are not functioning. All other keys are functioning properly, but I can not use the enter/= key, so it is basically worthless. And, sometimes after being on for a minute, it will power down on its own. Is there anything that I can do to repair it, or am I looking at buying a new one? Thank you for the help.

As far as the powering down goes, many calculators do that automatically, including the ti-89 series (at least mine does). In regard to the non-functioning keys, I would have to say that the circuit running that particular row of keys was fried in the accident, because the whole block has lost functionality, as opposed to a single key. It may be a prime opportunity to upgrade to a Ti-89 titanium.
hope that helps :)

I cant find my L1 buttom in ti 89


There isn't one. Unlike the TI-83/84, the TI-89 lets you use any name for lists. If you want a list (or any other item) named "L1" you can spell it out by pressing ALPHA 4 1.

I just got my sister's TI-89 calculator and I don't know how to use it. I'm trying to find out how to graph a non-linear inequality. Any ideas?


You can download the manual from the manufacturer's web site at
http://education.ti.com/calculators/downloads/US/Guidebooks/Detail?id=6128

There's also an aftermarket book:

If you're lucky, a local library will have it.

I cant really read some of the options on the screen on my ti 89....the letters are so blurry......what can i do ?????


Hey shrestha,

I've never seen a calculator with display clarity problems.

The only option I could think to offer you is to attempt to adjust the contrast. However, I'm not sure whether or not your TI-89 actually has an option to change the contrast. Because I own a TI-89 Titanium - and although its a wonderful calculator - it does not allow the user to alter the darkness/brightness of the display.

Call Texas Instruments: 1-800-TI- CARES...They are pretty helpful with common questions like this.

Sayonara,

Sticky calculater keys


First-take the batteries out. You should be able to take the case off from the back. Use a q-tip and alcohol. It will clean and dry immediately. Let dry a day to make sure there is no liquid in it before you put the batteries back in.

Ti-83 calculator went through wash


Best thing to do is to let it air dry. If you want to TRY to speed things up. Let it sit in a bowl of dry rice. The rice help to soak up the water. If you can take the back apart from the front and lay them down (insides facing the rice) on the rice, do it, but do it VERY EXTREMELY carefully. Do not push it down onto the rice, you'll damage the circuit boards. Let it sit for 6 - 8 hours. If still unresponsive, it's gone. Sorry!
