Question about Texas Instruments TI-84 Plus Calculator
It will not turn off, everything works all right.
You can probably just reset the unit to get it back to normal...
2nd>mem(+ sign)>reset>[ram](it's a menu)> Yes.
If that doesn't work you can do a full reset which will erase all applications on the calculator, but you can just reload them from your pc (not like it takes very long)
2nd>mem(+sign)>reset>right 2x(should say "ALL" at top)>Yes
This will reset the calculator to it's default behaviors

Your calculator is set in radians. Press mode key. Arrow down to 3rd line. Highlight degree and press enter. Your calculator is now in degrees, not radians. To get out of the mode screen and back to home screen, press 2nd and then mode.

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.

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, add a comment to this post and we'll go from there.

Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
"Waiting...Please install calculator software now". If calculator did not turn on or, is still locked up goto Procedure 3, unless already did Procedure 3, then goto Procedure 4. If you calculator does come on and is responding and, your connect to another calculator goto Procedure 1. If you calculator does come on and is responding and, your connect to a computer goto Procedure 7.
Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. Goto Procedure 2.
If the above process did not work. Try re-doing the Procedure 2, and, this time extend the time in Procedure 3, by 5 minutes to 10 minutes before you put all the batteries back in the calculator. These calculators can be a little stubborn at times so, keep trying Procedure 2.
If you can't find a calculator to connect too, 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.
Procedure 6. Procedure to installing the latest Ti84 Plus 2.55v. MP OS. TI OSDownloader does not always install the latest OS.
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. If your calculator will not turn on or, is locked up goto Procedure 2. Or else goto Procedure 7.
Important Note: Never disconnect a TI Connectivity Cable during a transfer. Lost of power during installation of OS will destroy your calculator.
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.
