Display assembly

All display assemblies include WLAN antenna transceivers and cables. WWAN models also include 2 WWAN

antenna transceivers and cables.

Full hinge-up displays are not spared.

This section describes removing components that do not require that you entirely remove the display

assembly from the computer. You can remove the display bezel, webcam/microphone module, and display

panel with the display assembly still attached to the computer.

To remove the remaining display components, including the display brackets, antennas, and enclosure, you

must remove the entire display assembly from the computer. See Display assembly subcomponents

on page 27 for more information about removing the remaining components.
