Texas Instruments TI-Nspire CX: TI-Nspire CX Cas Damaged Charger Port

Tue, 07 Sep 2021 08:37:33 -0700

This question is specifically for the CX CAS model of the TI-Nspire calculators.

The calculator is fully functioning except for the fact that it won't charge, unless the cord and charging port are aligned a certain way. It is not a problem with the cord, but with the charging port.

It seems that its contact points to the motherboard have been disconnected, as it has come loose and moves independently of the chassis, and only with luck can it be placed a certain way so that the calculator may charge. I would have to open it up and solder the contact points back to the motherboard, but I don't have the tools nor the know-how to do it.

I tried looking for ways to just charge the battery itself, since it can be easily removed with a Phillips screw driver, but haven't found the parts that would fit just yet. Any way to be able to charge it up would be appreciated.

Texas Instruments TI-Nspire CX: disassembly guide for nspire cx yellow edition

Sat, 11 Jul 2020 10:01:34 -0700

this nspire model differs from both the standard CX and the grey school edition with yellow highlights.

I see 4 screws to remove, but am still unable to disassemble.

Screen flashes white briefly when USB cable is plugged into power source, but does not boot or power on beyond the flash.

All visible screws have been removed.

Texas Instruments TI-Nspire CX: Why isn’t my ti-nspire turning on

Sun, 06 Apr 2025 04:35:01 -0700

My nspire had low battery and when I went to charge it it wouldn’t charge and so it shutdown but when I got a spare battery the device still won’t turn on or at the very least the display doesn’t work. I tried both the spare and the original battery on a different device and both worked for that device

Texas Instruments TI-Nspire CX: Boot failure, sudden restarts, glitchy screen, and unresponsiveness.

Thu, 05 Jul 2018 14:52:19 -0700

So the other day, I left Ndless on my calculator too long, and I took it out to find that there was a glitched screen left on all night.

TI-Nspire CX CAS
OS 4.4.0.532
Had Ndless installed (4.4.0 r2007)
Hardware revision O (0?)
Was using nPDF

Sudden restarts
Glitchy screen (Usually during restarts)
Does not respond to resets when reset button is pressed
- Restarts when disconnected from computer (Battery?)

Reinstall OS.
Delete, then reinstall OS.
Take out and put back same battery.

I would give images, but due to the buggy nature of this problem, it simply won't cooperate.

Update (8/16/17): Today my TI-Nspire CX CAS gave me a glitched TI-Nspire Classic boot. Of course, it glitched, but still, it was something.

Edit (11/20/17): My calculator doesn't turn on anymore. Help!
