Calculators Ti 89 not connecting to computer

  1. Apr 29, 2012 #1
    Hi guys, just found this site, hopefully you can give me some help with my calculator. I bought a ti-89 titanium at the beginning of fall semester, roughly 6 months ago. It has connected to my laptop fine since I had it, but just started having trouble the other day. When I connect the USB cable to the calculator, it shuts down within 10-15 seconds. Pushing the On or any other button does nothing, the only way to turn the calculator back on is to pull one of the batteries out and put it back in. As soon as you put the battery back in it restarts and goes back to where it was, without pressing the on button or anything. I got far enough once in TI connect to get the error "ti-89 connected, but couldn't get status". I did some troubleshooting online and tried forcing the loading of OS 2.09, as that is what the ti site recommends, even though my calc has OS 3.10. I could not get the calculator to stay on long enough to load the older OS. I tried resetting the calculator, also no help. This video I made shows what it is doing.

    I really need to get this going by wednesday for class. Any help would be great. Thanks

    I got it figured out. I put 4 new AAA batteries in and it works fine. I really didn't think that was it, as I was able to use it for hours after I tried connecting to the computer. Oh well at least I got it.

    I had this problem about a year ago and I ended up returning my calculator..! I would have never thought that changing the batteries would have fixed the problem. :-)
