Schematic for Quanta project Y73 at revision 2A, labelled in the name as an HP design code-named Napa built on the AMD Kaveri platform. No full motherboard part number appears in the name, so match the Y73 code and revision on the PCB silkscreen yourself. The 780 KB PDF is useful for following power rails, APU supply circuits and enable signals when tracking down a short or no-power fault. Quanta is the ODM behind many HP laptop boards, and variants of one project can differ between revisions, so verify before trusting part values.
