Schematic PDF, 2.13 MB, labelled only V6J. The short code looks like a model or project designation, but the name gives no brand, board number or revision. Open it in any PDF reader and check the title block, which usually states the board name and revision. A laptop schematic shows power rails, voltage regulators, charging circuits and signal paths between chips, which is useful for working through no-power or no-boot faults. Confirm the details match your board before using component values or net names.
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 @cyberlanelectonik. Enginerys does not host this file.
