Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator
I have to hold the key down for at least 2 seconds for it to registar what I am entering. I have changed the batteries. What should I do?
I tried blowing compressed air with a computer air duster into the I/O port. I do not know what this does but, it REALLY WORKS!!! My daughters TI-84 Plus Silver Edition is working fine.

Believe it or not, but the compressed air solution worked. Before trying compress air, I tried several things. I changed batteries, including the backup battery. I tried the DEL and CLEAR solution. I reinstalled its OS. I reset the calculator. I deleted the GARBAGE file, but the only thing that remotely worked was the compress air. Thank you!!

It sounds like the calculator's flash ram is expired or faulty. When a particular bit in the flash is accessed more than an arbitrary number of times, it will no longer be able to accessed. the best solution is just to replace the calculator, you can find some real good priced used ones on ebay or www.usedcalculators.com

Resetting and Upgrading to OS 2.43 did not work.

Calculator would turn on, but not respond to any keystroke. I searched the internet for remedies. I found the compressed air into the I/O port remedy here. I had tried everything and nothing worked. I tried this solution, and IT WORKED!!! It made no logical sense to me, but it worked.
Thanks to all who posted and verified this solution!

The TI website suggests (if all other things above didn't work) taking all the batteries out, even the backup batt. and leaving the unit empty for 5-10 min. Then reinstall batteries. This should return unit to factory settings.

If you just got it new then you should return it for an exchange or refund.
If it's a little older, it may be a bit too full (think of your computer running too many things, get's really bogged down.)
You can reset it by
or just go from factory defaults by
2nd>mem>reset>right 2x(ALL at the top of screen)>yes
if that doesn't work then I would suggest going to the TI website and getting the newest OS for your calc and installing that through TIconnect software.
