How many times has that happened, please? What happens if you try a few word test? Has this always behaved the same way, or what's changed?

Sounds like you may have variable set which is being applied to each function. A reset will not clear this. Check your sw version(be specific) and download the exact patch from the manufacturer. Of course, if you can remember where you set the variable, or even if you have defined a constant that is being referanced and can remove them that would be quicker.

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. 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 this doesn't do it, please append a comment to this post and we'll go on from there.

I had the same problem like yours. First, I reset the RAM and then it no longer turned off right away; but it responded extremely slowly. Second, I tried to install the new OS for it, but unsuccessful until I blowed really hard several times into the round connector. After that, the cursor started blinking. Finally, I downloaded the new OS into it and hoped that the problem never happen again.
You go to http://education.ti.com and follow their procedures to reset the RAM.
