Re: All buttons on my TI 84 are frozen
TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on at all. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If your programs are archived you can remove the main AAA batteries without losing them. If they are stored in RAM they will be wiped out. Just do not remove the Main AAA batteries and the button cell backup battery at the same time.
Unfortunately, you can only access RESET from within the menus of the calculator. You will have to remove all of the batteries and let the system naturally reset. The TI-84 Plus uses five batteries: four AAA alkaline batteries and one SR44SW or 303 silver oxide backup battery. The silver oxide battery provides auxiliary power to retain memory while you replace the AAA batteries. Re-install the batteries and reprogram your functions.
Hopefully this will get you around the problem for the time being. You can download a program called "Virtual TI" written by Rusty Wagner. You will also need to download the TI-84 ROM file from the Internet and place it in the folder with the Virtual TI program. Once Virtual TI is running, press F12 and select the version of the calculator ROM that you have. You can also try WabbitEmu.
I had the same problem. I remove all four batteries and the battery backup that is underneath the little phillips screw in the battery compartment. I immediately replaced it and the other batteries and everything worked. FYI, others have called for keeping the batteries out for 8 hours.
This is kinda a weird situation. Because it's usually the other way around. Your ram will clear if your calculator is frozen. So take out all 5 batteries from the back. Even the back up battery. Then reset it again. 2nd then + then 7 then 1 Then 2. Good luck.
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, and it worked perfectly after that. I hope this helps.
