Hi biancaaii,

You need to re-install the Ti 84 Plus OS, ASAP!!! You can fix the problem by installing the newest Ti 84 Plus 2.55v. MP OS. operating system.

If you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the IO link ports and, they can send you a copy of their OS while you receive it on your Ti 84 Plus. Hopefully your friend will have Ti84 Plus 2.55v. MP OS on their calculator or, it might not work.

If you can't find a calculator to connect to you can connect your Ti 84 Plus to a computer that has Ti Connect software on it. If you need to connect your Ti 84 Plus to a computer make sure the Ti Connect software is operating properly. You do not want any hang-ups while installing the Ti 84 Plus OS. Be careful, even a power failure during the process of installing the OS will destory your calculator.

Procedure 1 to installing the latest Ti84 Plus 2.55v. MP OS

1). You can get the latest copy of Ti84 Plus 2.55v. MP OS and, guidebook by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 84 Plus 2.55v. MP OS!" Once your at the Ti site click the Download Item, "Ti84 Plus family operating system". Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti84 Plus family operating system will download to you.

Next, click "SAVE" and then a window to a folder will pop up. It is probably a window to a folder that you download too. If so, you may want to change it and, save to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 84 Plus guidebook too, if needed.

Link your computer and, Ti 84 Plus calculator with the USB cable or, Direct Black Link cable that came with the Ti 84 Plus calculator. Next, drag the Ti 84 Plus 2.55v MP OS that you saved earlier in "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Click, "Continue" when the "Erase Warning" pops up and, the new Ti 84 Plus 2.55v MP OS will begin to install.

Next, the Ti Device window should pop up and, highlight the port when it finds what your Ti 84 Plus is using, USB1 cable or, Direct Black COM1.


When the Ti Device Explorer finds and, highlights your calculator's information click, "Select." Then click, "Yes" when the next window shows up with your calculator's information and, the OS will continue to download. Upon completion the newest Ti 84 Plus 2.55v. MP OS will be installed.

If you run into any trouble with software or, drivers just comment to what failed at this posting and, I'll be glad to help you.

No need for the disc. Go to the education.ti.com website. Click Download menu, select Software and apps, Select Graphing calculators, TI83PLUS/TI84PLUS family and find the TI-Connect 1.6 connectivity software.
Install it on the computer then connect the calculator to computer with the TI SilverLink cable . Open TIConnect, Drag and Drop applications on the TI Connect main window to transfer to calculator.

If you use the USB mini to standard (Direct cable) you may have to install the drivers.
In Windows, when the Found New Hardware window asks you to look for the driver do not let it do it automatically. , select option "Let me show you where it is (not the actual wording)" and make sure you select TI Educational Handheld.

Hello,
Press [ENTER]. It will display 6 on the next line. Whenever a cursor is blinking it is waiting for you to do SOMETHING.
Hope it helps.

The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is. 

Sounds like your pc had a static charge that it discharged to your TI and that it fried something inside the TI. No warranty, No fix. You gotta buy a new one.

well, the TI-84 does not do derivatives, however, the TI-89 does, if you are willing to fork over the $150 for it. It is definitely worth it if you are planning on taking Calculus BC and/or SAT II for Math Level 2.
