The key is marked x-superscript-negative-one and is just below the MATH key on the leftmost column of the keyboard.

SOURCE: TI 84 cant turn on

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.

SOURCE: comma key on TI-84 Plus Siver Edition calculator.

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.

SOURCE: Ti-84 Silver Edition received water damage and cant be switched on

try this :
This works on most mini electronic devices like cellular phones and degital cameras etc .

it sounds crazy .

Remove the back (or Cover ) of the phone( or Camera ), battery, and SIM if your phone ( or Device ) uses one , DIRECTLY
.

Then, with a q-tip (or something similar), dab the connection points (shiny, goldish) on the battery, SIM, and phone. This should aid in drying.

Finally, place all contents in a bag of uncooked rice (separately, do not put back together just yet). it sounds crazy , but it draws the moisture out.

It normally is working after just 7-8 hours, but I would wait 12 hours or even 24 hours before attempting to use (just to be sure).

beware the water damage, despite being dry now, will void any warranties. Also, the phone's hardware is now weakened and if you drop it, the green mother board and circuitry could shatter - so be more careful.


This does work on electronic devices aside from phones as well. Simply tailor it to your device. If you do not have a SIM (Verizon phones, cameras, all others), remove only the battery. If you have an iPhone/iPod or GPS and cannot remove the battery, simply make sure it is all the way off, then put it in the rice bag. All electronic devices react the same to the rice trick.

SOURCE: Change TI 84 OS to TI 89 OS??

And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or amazon.com and spare your TI84PLus SE.

SOURCE: my computer won't find my ti-84

Even if you cannot connect it to the computer you can still transfer applications from a working calculator.

Here is a copy of a post I wrote to answer that question.

If you have a USB SilverLink cable, use it to connect the calculator though the I/O (round) port.
If you do not have a USB SilverLink cable, you can use the mini USB to USB Direct cable but you will have to install the correct driver for it.

I do not know what computer operating system you are running and I use Windows XP so I will describe the installation procedure for Windows XP SP3.

Install TI connect 1.6 for Windows; if your system is Vista you must install a patch available on the TI website, at the same page where you find TI Connect.

After you install TI Connect, connect you calculator to the computer with the mini USB standard USB Direct cable. Windows will detect the calculator and will try to install the drivers. You will have something that is similar to what is on the three screen captures I am inserting in the post. On the last screen, choose the TI Educational Handheld device and click next.

When Windows asks to stop installation, click continue anyway

After the installation, click finish.

Device manager will show you something like what is on next screen (TI Educational Handheld device)

Run TI Connect to verify that the calculator is recognized. Connect your computer to the Internet and click the Updates Button on the TI Connect tool bar.

There is no such thing as a TI89 Plus Silver Edition.

If you mean the TI-89 or TI-89 Titanium, press diamond / (the diamond key below the 2ND key, then the divide key).

If you mean the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition, press MATH left-arrow 4 .

My calculator is extremely slow and i cant fix it


Here is for you. From the TI Knowledge base.
Why does my TI-84 Plus or TI-89 Titanium respond slowly to key press entries?

Issue/Symptom: When making key press entries, the product responds slowly

If a piece foreign material such as a pencil lead is lodged in the I/O port of the calculator, it may create a short causing the calculator to respond slowly to key press entries.

If the piece of conductive material can be removed, it may restore the calculator to normal operating condition.

If the material cannot be removed, contact TI-Cares Customer Support to proceed with an out of warranty product replacement.

If conductive material is not lodged in the I/O port and the calculator responds slowly to key press entries, contact TI-Cares Customer Support for further troubleshooting and resolution.

TI 84 plus silver edition we cant get it to stop rounding off the numbers


Press MODE to bring up the mode screen. Use the arrow keys to highlight "NORMAL" on the top line and press ENTER. Highlight "FLOAT" on the second line and press ENTER. Press 2ND [QUIT] to exit the mode screen. Now you will see full precision on subsequent calculations, though the TI-84 will still suppress trailing zeroes.

I haven't really used a TI-84 before, but if I'm not mistaken, the reciprocal key is the x raised to -1, see here: 99d0a9b.jpg
