Some advice on how to take Ti Nspire CX apart

[jdcx]

I recently brought a few Ti Nspire CX school property calculators. I need to fix something inside, so I will need to take it apart. I searched online on how to take it apart and got some misleading information. By following those instructions, I destroyed one of my calculator. The instructions say you need to take the face plastic protect cover off first to reveal 2 hidden screws. The truth is for both the white border and yellow border school property ones, there is no hidden screws. You just need to remove the 6 screws at the back, then you can take the back off. The white border one is much easier to take the back off than the yellow border one. But both of them are not hard. I do took of the plastic face off, that is also doable, just need to be a bit careful.
