Main Question or Discussion Point

Hi, my cousin just gave me his Ti-89 Titanium calculator so I can use it for my classes which require heavy math, but it has a problem. The calculator will not shutdown and the screen will only go blank for a second and turns back on to its original state when I press 2nd and off to shut it. The way my cousin shut it before is to remove the batteries. I was wondering if there is any way to fix this on the Ti by myself without such a hassle of removing the batteries after every use.

You can contact TI by e-mail (ti-cares at ti dot com) or 1-800-TI-CARES to see if they can offer any help.

EDIT:
A little googling finds the following:
I was able to fix the problem nut it requires several steps and only offers a temporary fix (untill the calculator is reset then it needs to be done again).
1. Press F5, then Dimond (symbol on buttion) then "Clear"
2. Press "alpha" then "S"
3. Press "0" dont mess with anything else here
4. Press "2nd" then "Quit"
Now you can turn it off but are missing the bottom text (rad,auto, etc...) to fix
6. Press "Mode" change radian to degree then "enter"
Now the text is displayed showing the mode.
7. Set the mode back to radian by reversing step 6.
Thats it I dont know how to get the bottom line back though...

Turn down the contrast. You probably turned up the contrast while the batteries were dying, and now that you have fresh batteries, you need to turn down the contrast.
