Quanta Y02 schematic for board DA0Y02MB6C0, revision 1A, associated with an HP project the name calls Mario, likely an internal code name. It is provided as a 586 KB RAR archive. Because no retail model is given, confirm the match using the DA0 number printed on the PCB, which follows Quanta's ODM numbering, and check the revision too. The drawings help a technician follow the power-on sequence, trace rails from the adapter input and find components behind a short. Extract the files and open them with a standard PDF reader.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
