The screen is attached to the chassis by a strip of adhesive that runs all the way around.
To detach it we will apply heat to soften the adhesive and to peel off easily.
We suggest 2 methods:
After applying heat to the glass of the touch screen, insert a prong between the glass and the chassis. Scroll around the contour, avoiding cutting the data flexes when passing.
Separate the glass progressively, starting at the bottom, leaving the data flex to the end.
Pass the flex cable from the opposite side so that it does not get stuck or damaged.
Remove the adhesive with translucent windows from the leds of the front keys.
Peel off the chassis plate with the metal spatula.

We will need to bend one end of the flex carefully to be able to pass it through the slot towards the opposite side and thus extract it.
