Loosely named 5.89 MB zip for an HP ZBook, with no model generation, board number or revision given and no hint of what it contains. Unpack it and identify each file: schematics usually come as PDF, boardviews in formats such as BRD or BDV, and firmware as BIN images. HP mobile workstations are built by ODMs like Quanta, Inventec or Wistron, so compare the board number printed on the PCB with anything inside. Back up the existing flash before writing any dump.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @azvoltagemap. Enginerys does not host this file.
