I was very careful doing mine, but the real things to watch out for (more than the LCD screen) are the touchpads. Those things can’t be recalibrated, and there are no replacements. You can adjust the sensitivity everywhere but in desktop mode, but it makes the keyboard damn near impossible to use. Again, I barely touched them and had no issues reconnecting them, but when I got everything back together they were way too sensitive.
I just want to be able to calibrate the touchpads outside of desktop mode, or at least the keyboard.
