Question about Texas Instruments TI-84 Plus Calculator
So my calculator has been acting really funny right now..
When I turn it on, the cursor does not flash, the buttons have to be held for about 3 seconds before they do anything. The unit also does not turn off or sync to the computer (i just take the batteries out). When i put the batteries back in the calc behave the same as before saying ram cleared when it turns on...
please help I have finals coming up in 3 weeks....
The I/O plot matters. If blowing doesn't help, insert a stick or something into it. I had the same problem, and my TI 84 plus had already been extremely unresponsive and slow before, as I fixed the latter problem by blowing really hard into the I/O plot, I did the same to fix the new problem. For many times nothing happened. Then I insert a metal stick into it and gently hit it inside. In a short while, the calc was normal again!! Now my calc even turns on when it's been put off, with its cursor frozen. I simply use my little finger to dig/scratch the plot and see the lovely cursor beating again. PS Having such a funny calc is really bad, but every time you fix it you'll feel good

I actually fixed mine!!!! The same thing happened to me. I found somewhere that the no/slow key response could be due to a short in the I/O socket. I blew into it really hard (you may want to use compressed air, but I didn't have any onhand), and it works perfectly now!!!!!!!!!! I hope this helps.
