Be sure to get just under the glass. There is a thin black edging under the glass. I found it better to start at the bottom edge.
There is a lot of glue, and it is about 1/2” wide.
Do no overheat. The frame is plastic and can deform.
If you want to preserve the screen, be careful near the bottom edge near the windows logo. There are 2 flex cables, one on either side of the logo. If you stab a tool too far in, you may tear a cable.
If you have a new screen “without cable”, the directions are slightly different. Do not disconnect the ribbon cable from the motherboard. Instead, locate and remove 3 hexalobe screws that attach a narrow circuit board to the display. Carefully lift the narrow circuit board, disconnecting two sockets from the display board. Roll this narrow circuit board over and locate 2 flex cables. Lift the flaps on each flex cable to reveal the zif sockets underneath. Use a fingernail or plastic spudger to lift up the catches on the zif sockets and slide out the flex cables.
