Question about Texas Instruments TI-84 Plus Calculator
I was doing some basic addition and subtraction sums while i was doing some solidworks stuff. i did a couple calculations, got the number and put it into solidworks when i came back to the calculator it stopped working it just locked up on the screen it was on. Wouldn't let me turn it off or anything. I pulled all the AAA batteries out and turned it back on the cursor is just black and doesn't blink. I pulled the little backup battery out and it had the same effect. is there anything i can do?
the screen may be at the lowest dim setting, try turning it on, then pressing the 2nd key and then hold the up key and see if anything appears, if not let me know and I will try to figure out something else, I own a 83, 84, and 89 so it shouldn't be too hard to figure out

Go onto www.education.ti.com, find the downloads column, and click on apps and operating systems. Then you can click on the different lists and find out which apps you accidentally deleted. You do this by (after clicking on it) looking under the "Pre-Loaded On" column. If you find the name of your calculator there, this is one application that was deleted. Hope this helps!

Well, to answer part of your question, yes... the TI-89 does factor like this. it is inputted like this:
Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()

Remove all four AAA batteries. Press and hold down the ON key for at least ten seconds. Replace the batteries. Turn the calculator on.

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 that doesn't work, try a hard reset. Remove one of the four AAA batteries. Press and hold the ON key. While holding down the ON key, replace the battery.
