Zipped boardview for the HP laptop built on the Quanta U93 motherboard. The revision field in the name is blank, so the exact PCB revision covered is unknown. Boardview files show the part placement and net connections of both board sides and are opened in viewers such as OpenBoardView, FlexBV or Boardviewer after extraction. They help you locate components, test points and shorted nets quickly. Compare the revision printed on your PCB with the one shown inside the file, because pads and parts can move between revisions.
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 @boardview. Enginerys does not host this file.
