    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 this doesn't do it, remove all four AAA batteries. Press and hold the ON key for at least ten seconds. Replace the batteries. Turn the calculator on.

    Does this do anything?

Having gone over a month without a response, I assume the suggested reset solved the problem.

I need a manual for the ti 93 plus.


The Ti93 Plus does not exist. There are however a Ti92Plus and a TI83Plus. The manual for either of them can be downloaded from this page.

My TI-nspire CAS doesn't want to go on! I changed batteries! Tried the contrast buttons! Nothing works


Hello,
Try the other recipes from the TI knowledge base concerning a calculator failing to turn on

For the TI-Nspire™ Family:
  1. Remove thekeypad (for TI-Nspire) or the battery door (for TI-Nspire CAS) andremove at least 1 battery from each column of batteries. After 2-5seconds, reinsert the batteries and turn the unit on. This will causethe unit to reboot the operating system.
  2. Remove the keypad(for TI-Nspire) or the battery door (for TI-Nspire CAS) and remove atleast 1 battery from each column of batteries. After 2-5 seconds,reinsert the batteries and LEAVE THE UNIT OFF (do not turn on and thenback off). Hold down [Home] [Enter] [P], and while holdingthese keys, press [On]. The device will boot up as in the previousreset, but will display a menu with the following options. Please tryoptions 1, 2, 3, and 4 in that order. ** The [Home] key is located atthe top right of the TI-Nspire keypad and has a picture of a house onit.
Note:TI-Nspire family model options 2 and 4 above require that the OS be installed. The reset menu will only display if the unit is off and batteries have been removed/replaced as described above.

1. Cancel - The most non-intrusive reset option; no changes are made, the unit restarts.
2. Delete Operating System – The operating system will be deleted without deleting any documents.
3. Delete Document Folder Contents – This will delete the user’s documents, but will not delete the OS.
4. Complete Format – This will delete the OS and all documents for a total erase of memory.

Hope it helps you solve the problem.

TI 83 Plus won't turn on after battery change


I was having the same problem...I found the info below on another blog and it helped me fix my calculator problem. Take out all the batteries, hold the DEL button and put the batteries back in (keep holding the DEL button until all batteries are put back in). This will restart the calculator and restore it to its default settings...but it makes it work again!

"Reflashing the OS is probably the thing to do now. I think there's some trick that throws the calc into OS receiving mode. Hold down DEL while putting the batteries in? I don't remember if that's it. Go to 1-800-TI-CARES/ti-cares@ti.com if you need specifics on getting the calc to take an OS upload given the state it's in."

TI- 92 crashed


Hello,
I would not let it lie to rest yet. Play again with the contrast: Lower it so
Press [diamond] key the green one beteen the [ON] and [2nd].
If that does not work it may be because by removing the batteries while the calculator is [ON] you might have pressed inadvertently a button on the keyboard, and that can lead to erasure of the OS. Besides, you cannot change all batteries at the same time:Backup batterie should be in and in good working order when you change main batteries. Similarly, main batteries should be in place when you change backup batteries.

There may yet be a chance to get it back to life and that is to install the operating system through a computer.
You need the cable (TI SilverCable from Staples or Office Depot).
You need to download The TI Connect Software from education.ti.com and install it on the computer.

After installing the software on the computer, run TI connect, then connect the calculator to the computer, and press the [ON] key. Usually it turns on as soon as you plug the TISilvercable into the calculator port.

In the TIConnect window there are several icons (TI device explorer, TI Screen Captrure ) You may try to use them to see if the calculator responds. If it does you calculator is not totally damaged).
Whatever the results of the foregoing actions, you should try to install the OS.

At the top of the TIconnect windows there are 4 round buttons (2 green, 2 gray). Click the Update button. (you must be connected to the Internet) If it works, I congratulate you. If it does not, I have no idea what you might do next.

Hope it helps.
