Removing display assembly

1. Disconnect the EMR sensor cable [1].
2. Remove the single (M2.0x3.0) screw that secures the wireless bracket to the system board [2].

   NOTE: : The screw securing the display cable bracket also secures the left IO bracket to the system board, as a result removal of the display cable bracket leaves the left IO bracket unsecured. Technicians should therefore, ensure that the left IO bracket is not moved or lost during any subsequent disassembly processes.

7. Open the system to 180 degrees and place the computer on a flat surface, with the display hinges facing up.
