    Press ON, and then 2nd, [up] arrow. Sometimes the screen intensity is changed [some *** of a friend!] and it appears that the calculator is broken.

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.

  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.

Did you try [left][right][2nd][on]? It reinitializes the memory and clears the ram.
