The HP 848242-001 display hinge kit is a paired replacement assembly for the display section of a compatible ZBook laptop. It brings together the left and right hinges, the components that connect the screen assembly to the computer’s body and let the display open and close.
The part number is identified for the HP ZBook 15 G3 by a distributor and is listed as a display hinge spare part in HP’s ZBook 15 G4 Mobile Workstation service guide. This provides a specific model reference for the kit and confirms its role within the laptop display assembly.
This is a hinge assembly, rather than a display panel or display cable. The confirmed kit description covers the left and right hinges; no other package contents are specified.
