Schematic for the Quanta ZO1 motherboard in PDF format, about 873 KB, with no revision or model information beyond the board code in the name. Quanta is an ODM that labels its laptop designs with short codes like ZO1, so the retail brand may be different. Technicians use the drawing to follow power rails, check the charging and EC circuits, and find components related to a fault. A regular PDF reader opens it. Read the revision from the title block and confirm it matches the number printed on your board before relying on values.
