How to fix the TouchPad arrow keys on nspire CX
Posted: 14 Aug 2023, 22:37My ti nspire cx TouchPad arrow keys are not very responsive. You need to press it very hard and try many times to make it work once. It almost made the calculator unusable. I decided to take it apart and fix it. I found out the problem is the little metal click pad on top of the switch is not that clikcy anymore. Ideally you need to replace that, but I couldn't find them for sale anywhere online. There is a thin plastic membrane on top of those click pads, in order to take them off, you need to use small nife to cut around the click button. I just cut that 8mm metal click button off and peeled the plastic on top if and put it back. Magically, it works well now. I think it may because by removing the plastic, the button has more room to response a click, who knows. I don't know how long it will last, but better than not working at all.
