RAR archive for the Quanta ZHNB motherboard project, 2.61 MB in size. Only the project code appears in the name, with no revision, board number or description of contents, so extract it and check whether it contains schematics, boardview data or both. Such documents help trace charger, VRM and power-sequencing circuits and find test points for measurements. Quanta silkscreens a DAZ- or DA0-prefixed number with a revision letter on its boards. Match it before trusting the data.
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.
