| Everything was ok with my TI-89. After a long travel with my device and finished my journey, I tried to turn it on, but it did not work at all. I think about the batteries and changed them, but I could not get any respond. I checked the new batteries with multimeter and they are healthy. I also removed the back up battery for about a minute. All above did not work. Please help me on this topic. |
