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.
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.
I'd try hooking it to the computer using ti connect explorer and see if deleting the programs there would help. I had a calculator that did the same thing and never did fix it. But if your memory can be delete and reinstalled it might work.
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.
try taking out a battery; if that doesnt work, all four; if THAT doesn't work, take out the watch battery as well; if THAT doesnt work, take out everything and leave it overnight
