Compressed RAR package, about 1011 KB, for the Quanta ZRQ project at board revision 3A. The name gives no laptop brand or model, so the matching notebook has to be identified from the board itself. Quanta uses short three-letter project codes like ZRQ, and the full board number normally takes the form DA0ZRQ followed by MB and a suffix. A schematic inside would let you follow power sequencing, measure test points and locate parts. Confirm that the revision printed on the PCB is 3A before trusting the values.
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.
