The HP M73451-001 LCD cable is a replacement display connection part for the HP Chromebook x2 11-da series. It links the computer’s display assembly with the system so the screen can receive its display connection.
HP lists this exact spare part as the display cable for the 11-da0xxx family, and a parts listing identifies it for the 11-da0000 (3G0N5UA) configuration. The part number helps distinguish it from nearby display components.
This is the LCD cable; the separately numbered M73450-001 is the touch control board cable.
