Loading Screen Freeze

When I use either keypad for the ti-nspire it goes through the loading phase until the loading bar is completely filled. At this point the screen freezes and is not responsive to anything. I can take the keypad out and hit the reset button on the back but the message on the screen stays the same. i tried changing the batteries and that doesnt work. suggestions?

  1. Remove the keypad (for TI-Nspire) or the battery door (forTI-Nspire CAS) and remove at least 1 battery from each column ofbatteries. After 2-5 seconds, reinsert the batteries and turn the uniton. This will cause the unit to reboot the operating system.
  2. Holddown [Home] [Enter] [P], and while holding these keys, press [On]. Thedevice will boot up as in the previous reset, but will display a menuwith the following options. Please try options 2, 3, and 4 in thatorder.

    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.
    Note: TI-Nspire family model options 2 and 4 above require that the OS be reinstalled. The reset menu will only display if the unit is off and batteries have been removed/replaced as described above.

My TI NSPIRE CX CAS is stuck at the loading screen - it keeps loading and then going back and repeating (only when plugged in). I have tried resetting it whilst holding down EE, doc and enter. When I do...


For the TI-Nspire and TI-Nspire CAS handheld units with TouchPad and
the TI-Nspire CX and TI-Nspire CX CAS:


• Hold down [doc] [enter] [EE].
• While holding these keys press [on].

Please Note: For TI-Nspire Family handheld units that
contain rechargeable batteries you can alternatively hold the above
keys while pressing the [reset] button on the back of the handheld rather than
removing the battery for 2-5 seconds.

• The device will boot up as in the previous reset, but will display a menu
with the following options. Please try options 2, 3, and 4 in that order.
• 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 on the system.
• 3: Delete Document Folder
Contents - This will delete the user's documents, but will not delete the OS.
Selecting this option is the same as using the RESET hole on the back of the
unit.
• 4: Complete Format - This will delete the OS and all documents for a
total wipe of the handheld.

Please note that the second and fourth option will require that the OS will need to be reinstalled.

My ti nspire cx cas is totally stuck at the loading screen , it keeps reloading and reloading with a sign at the left corner at the bottom that say's that my battery is empty ? what should i do ?


I have a doubt, when I choose to completely format the calculator it will clear your operating system, files saved on it, but the product key (ID protuto) will be deleted too?32d3cd84-9b87-4f5d-abfe-aa04ca86df4c.jpg

Ti-nspire with 84 keypad problems


It seems to me that you get the loading bar when you switch keypads. I just switched keypads, and when I reinserted the TI84 Plus keypad back again I found my last TI84 Plus screen contents still displayed.
As to the RAM cleared message, it probably is related to the batteries being depleted.
To verify battery charge level, you may use TI connect.

I installed the new 2.1 OS to my TI-nspire and when it restarts it always freezes at the "loading os" screen with the bar completely filled all the way.


First of all you will need to erase your calculator by holding Home(house key)+enter+P and than the on button. Make sure the on button is the last button you press. Then, select option 2 to erase your operating system. Then, you need to obtain the operating system 2.0 for the calculator. Download and install that onto the calculator. It should install operating system 2.0. Once you do that, download and install operating system 2.1. This will allows you to upgrade your calculator to the latest version and get past the full bar loading screen. Let me know if you need anymore help.

I have a TI-nspire CAS calculator. When it is switched on it begins loading and then comes up with System Error. What do I do?


Hello,
You should ( a suggestion) reset the OS by pressing the button on the back of the unit.

If that does not work, you may consider reinstalling the OS. The procedure as described in the TI Knowledge Base is as follows.

What steps are required to reinstall the TI-Nspire family operating system?

To reload the device’s OS using a computer with TI-Nspire Computer Link:
• Connect the TI-Nspire device (with the Nspire keypad) to the computer using the USB Standard A to Mini B cable.
• Open the TI-Nspire Computer Link software. The select device dialog should appear, and detect the device.
• Either drag the OS file (available in the ‘downloads’ area at education.ti.com) onto the TI-Nspire File Browser portion of the window, or click Tools -> Install OS.
To reload the device’s OS using another TI-Nspire or TI-Nspire CAS device:
• Connect the two devices using the USB Mini A to Mini B cable. The end marked A should be inserted into the sending unit, while the end marked B should be inserted into the receiving unit.
• On the sending unit, access the document chooser by pressing [Home] [7]. Once in the document chooser, press [Menu] and choose 9:Send OS…
NOTE: Users can only send an OS to a unit of the same model. Users cannot send an OS from a TI-Nspire to a TI-Nspire CAS.
Please see the TI-Nspire guidebooks for additional information.


Hope that helps.
