HP L77464-001 Hinge Kit TS is a replacement display hinge set for supported HP ZBook 15 G6 touch-screen configurations. It is intended for restoring the hinge hardware that lets the display open and close while remaining attached to the notebook.
The service guide identifies this part number for touch-screen models and specifies that the set contains both the left and right display hinges. This distinguishes it from the separate hinge part listed for non-touch configurations. The catalog also identifies L77464-001 as an HP laptop spare part under the name Hinge Kit TS.
Use this set when replacing the display hinges on a compatible ZBook 15 G6 configuration. The confirmed package contents are the two hinges; the available source does not specify additional screws or other accessories.
