    • Remove the three 2.0mm screws using the Phillips #00 Screwdriver bit.

    • Use the heat gun to loosen the adhesive around the perimeter of the screen(the solid black section).

    • The spudger tools can then be slowly worked under the screen to gradually lift it away from the case.

    • Due to the close proximity of the digitizer to the adhesive, if that component is not being replaced take care not to scratch the screen with the spudger.

    • Under the top section where the Lenovo logo is lies a copper strip that has adhesive on both sides. It is easiest to get under that strip when you start from the bottom and work up.

    • Next step will show the copper strip.
