HP N86530-001 hinge covers are replacement display-assembly covers for the hinges of a compatible HP laptop. The service guide identifies this part number with the Nightfall black finish, distinguishing it from the slate blue hinge-cover part.
The guide lists hinge covers for the left and right sides of the display. During installation, it specifies positioning each cover according to its left or right marking. This makes the part useful when replacing the matching display hinge covers during laptop service.
The part is identified as a hinge-cover component; the guide lists the actual display hinges separately.
