Zipped boardview for an HP Victus mainboard, part number DAG3MAMBAE0, revision E. The DA...MB...0 numbering is Quanta's, so Quanta manufactured the board. A boardview shows component placement, part names, nets and test points, which helps you locate power rails, follow signals and find shorts while probing the board. Unpack it and open the file in a viewer such as OpenBoardView, FlexBV or a similar tool. Compare the number and revision silkscreened on the PCB with this file before you trust the pin and net data.
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 @cynetitsolution. Enginerys does not host this file.
