Compal LA-H331P boardview packed in a ZIP archive of 834 KB, which according to the name holds the layout in BDV and PCB formats. A boardview shows every component outline, pin, net name and test point on the board, so it pairs well with a schematic when you trace a power rail or hunt a shorted capacitor. Programs such as OpenBoardView, FlexBV or BoardViewer handle these formats. LA-xxxxP is the Compal ODM numbering, so the laptop brand may differ. Confirm the code silkscreened on the PCB matches before probing.
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.
