Do you see anything on the screen? 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, post a comment here and we'll go on from there.

Installing


Try to find a classmate who has the same calculator (TI84 Plus or TI84 Plus Silver Edition) and effect a transfer of the OS from the classmate's calculator using an IO cable.
Alternatively, download the new version of TI Connect (version 4.) and install it on your computer. Then connect your calculator to the computer through the USB cable. When it recognizes the calculator click the update button in TI Connect interface and select update OS. Good luck.

I spilled gatorade on my TI84 graphing calculator..what should i do?!


Do not attempt to turn the calculator on for several days. Remove the batteries. Once the electronics (battery compartment especially) is dry, you can attempt to power it back up and it may or may not work.

My TI-84 calculator lost its cover for the batteries. Since then it sometimes can't turn on or show anything when I push the button "on". But sometimes it still can work. But because I havent...


Hi twylazhangzh,

Sound like your Ti 84 Plus is really over loaded and, can't function properly. You can fix that 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 just keep following my instructions below.

First, you need to download and, install Ti Connect to your computer. If you don't need any help installing Ti Connect goto Procedure 1.

If your computer's OS is XP or Mac and, you need instructions to download and, install Ti Connect click, "Install Ti Connect on my XP or Mac OS". Just follow Procedure 1 at that posting and, come back to this posting to finish downloading and, installing Ti84 Plus 2.55v. MP OS to your calculator.

If your computer's OS is Windows 7 and, you need instructions to download and, install Ti Connect click, "Install Ti Connect on my Windows 7 OS". Just follow Procedure 3 at that posting and, come back to this posting to finish downloading and, installing Ti84 Plus 2.55v. MP OS to your calculator.

Procedure 1 to installing Ti84 Plus 2.55v. MP OS

1). You can also 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 found that 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.

I dropped TI84 silver and now it won't work at all.


If you open the battery case and then open the lithium battery case (with a screw driver), there is a "reset" hole inside the lithium battery case area. Use a small screwdriver or something that will reach inside the reset hole and press. Good luck!

Why do some TI83 program work on a TI84 plus and other don't?


Ti 83 and ti84 really have no difference and operate the same. There was something different or you had varibles used by multiple programs that conflicted w/ the ti84 and it would have done the same on the ti83. If you like to rework it and need help email me at raklein62@yahoo.com
