Boardview for the Dell Precision 7740, Compal board LA-H281P, with the file marked as BDV format inside a 358 KB RAR. The LA-prefix follows Compal numbering. Paired with the matching schematic, this layout lets you find components physically, follow nets across layers and choose probe points when hunting a short to ground. BDV files open in viewers such as OpenBoardView or FlexBV; check that the board number and revision silkscreened on your PCB agree.
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 @pkbiosbdv. Enginerys does not host this file.
