Boardview file in BRD format for what the name identifies only as LI6J, delivered in a 101 KB ZIP. LI6J matches a Quanta project code, though the name gives no laptop model, board number or revision, so verify the PCB markings before use. BRD layouts open in OpenBoardView, FlexBV and similar tools, where you can search part designators, view pin nets and locate test points while diagnosing shorts or missing voltages. Ideally pair it with the corresponding schematic for full circuit context.
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 @schematicslaptop. Enginerys does not host this file.
