Occasionally, things go wrong on the TI-Nspire. If your handheld doesn’t turn on, the key presses don’t respond properly, or the display is garbled, you need to take action. Try putting new batteries in first, but if that doesn’t work, follow these steps to access the Maintenance menu:
Remove the keypad and remove one battery from each column of batteries for 2–5 seconds. (Not applicable to TI-Nspire CX)
With the handheld turned off, follow the steps below:
TI-Nspire CX: Press [DOC][EE][ENTER], and then, while holding these keys, use a pen to press the Reset button on the back of the handheld.
TI-Nspire Touchpad: Press [DOC][EE][ENTER], and then, while holding these keys, press [ON].
TI-Nspire Clickpad: Press c·P then w.
The TI-Nspire loads the Maintenance menu. Here are the four options from which you can choose:
Cancel. Handheld will reboot: This option makes no changes except to reboot the handheld. This is the safest option.
Delete Operating System: Choosing this option means that you will have to restore the operating system.
Delete Document Folder contents: This is exactly like pressing the Reset button on the back of the handheld. All documents are deleted, but the OS remains intact.
Complete format (includes operating system): This is the most powerful reset available on the TI-Nspire. All documents are deleted and the operating system will need to be restored.
If these options do not successfully fix the problem, you need to call in the experts. Call 1-800-TI-CARES and a Texas Instruments representative will guide you through the steps to repair or replace your handheld.
