Circuit diagram set for the Quanta LZ7 motherboard, board number DA0LZ7MB8E0, in PDF form at 1.14 MB. It appears to be another copy of the same LZ7 schematic and should open in any standard PDF viewer, with searchable net names in most such files. Use it to locate a MOSFET, check which rail feeds a given chip, or trace the path from the EC to the power buttons and charger circuit. Quanta is the ODM behind this numbering pattern, so check that the code printed on your board matches exactly, including the last revision characters.
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 @abgm_manutencao_esquemas. Enginerys does not host this file.
