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.
