If pressing the yellow 2nd key, and then pressing the ON key isn't working, try removing the batteries and then re-inserting them.

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.

Cant find ! button


There is no such thing as a TI89 Plus Silver Edition.

If you mean the TI-89 or TI-89 Titanium, press diamond / (the diamond key below the 2ND key, then the divide key).

If you mean the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition, press MATH left-arrow 4 .

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,

When I turn the switch on, ti-89 titanium does not turn on.


If you connect calculator to computer using Ti connect device explorer you might be able to see what files are on the calculator. I don't know if you downloaded from the web but, 3rd party programs and shells tent to miss up the calculator. This would able you to delete out possible problems which could be re installed later.

Ti 89 Titanium


The only option or keys that will work is the ENTER key and the arrow keys. Try to get your arrow key to work by arrowing down and hit enter hopefully change you to something different.
Next, if at all possible can you hit the MODE key or get into the mode. If you get into the MODE select F3 and then arrow down twice or all the way to the bottom and at APPS Desktop select 1:OFF and then hit the ENTER key. Next, What I really think you need to do is reinstall the Ti 89 OS software. To do so you would need to connect to your computer or another Ti 89 Titanium to your Ti 89 Titanium. If you have Ti connect computer software (from the Ti site) connected to your Ti 89 Titanium it might help you more in troubleshooting any further problems too. You might be able to delete corrupt files that would free your calculator up and start running better.
