I have tried to press the 2nd left/right arrow and on buttons at the same time; it reboots but the screen is still frozen. I have also taken out all the batteries and the back up batter but i had no luck. I also tried plugging my 89 into the computer through the black usb cable taken out one battery and held down the apps button as i put the battery back in. I then tried to do the ti connect os download but it cannot find the calculator even though i know the cables are plugged into the devices correctly. What should i do now. I don't have a warranty on my calculator and it is over 1 yr old. Is it worth sending it in to get it fixed by the ti company or should i just buy another one. Please any thing that i can try before buying another 89 or sending it in i would be grateful to try. Thanks so much.
