Steps
1. Remove the two (M1.6x3) screws that secure the display cable and Type-C bracket in place.
2. Remove the display cable and Type-C bracket off the computer.
3. Disconnect the camera cable and display cable from the connectors on the system board.
NOTE: The connector for the display cable utilizes a latch that locks it in place on the system board which technicians
must flip open in order to disconnect the display cable from the system board. After flipping open the latch, technicians
must grasp the left and right sides of the cable's connector head and disconnect the display cable from the system
board in a direct upward motion to prevent damage to the connector's pins.
CAUTION: Do not attempt to disconnect the display cable from the system board without flipping open the
latch first.
4. Open the display assembly to a 90-degree angle and lay the computer on the edge of the table so the palm rest is laying flat
on the table and the display assembly is over the edge.
5. Remove the six (M2.5x4) screws that secure the display assembly to the computer, press the edges of the system near the
hinges, and lift the hinges in the upward direction away from the computer.
6. Lift the display assembly off the computer.
NOTE: The display assembly is a Hinge-Up Design (HUD) assembly and cannot be further disassembled once it is
removed from the bottom chassis. If any components in the display assembly are malfunctioning and need to be
replaced, replace the entire display assembly.
