Serious TI-Nspire issues
« on: September 16, 2014, 11:04:28 am »
Okay, so my TI-Nspire is having two pretty devastating issues.
1) When put in sleep mode upon reawakening it crashes often
2) The keys are often mapped incorrectly upon reboot, for example menu acts as shift and 2 acts as the letter j, etc. This takes anywhere from 4-10 reboots to fix (I have not found a consistent solution)
I have tried deleting everything on the calculator using the maintenance menu and that has not helped. Any assistance would be greatly appreciated!

Which model of calc is it? I could imagine a calc with a removable keyboard (non-CX, non Clickpad CAS) could have issues with dirty contacts on the keypad. Other than that, is it running ndless, and which OS and boot code versions?

(actually I have quite a few more than this, but I don't feel like making bars for them all.)

It is a TI-Nspire CX running ndless with OS 3.6. Boot codes: boot1: 3.0.0.99 boot2: 3.2.4.7 (I can flash the older boot2 but it doesn't make a difference)

Looks like a HW fault, you'll have to send it in :-(
You can try the diagnostics to find the fault, if you want to.

Can such fault be caused by Ndless programs or is it simply an hardware defect from when the calc was manufactured? WIth all the recent topics about broken TI-Nspires I have been worried about trying new Ndless utilities lately, let alone upgrading to OS 3.6.

Theoretically everything is possible, but I can't imagine any software could switch the keypad layout forever.
There is likely related information in the bootdata area of the flash, but then boot2 would refuse to boot the installed OS as it wouldn't be compatible for the hardware model.
