PDF schematic for the HP nx6320 laptop, around 1 MB in size. The name gives no motherboard number or revision, so compare the board identifier printed on the PCB before working from it. These diagrams serve for tracing voltage rails, finding the MOSFETs, regulators and capacitors on each supply, and following signals when a machine does not power on or fails to boot. Values and part numbers can change between revisions, so cross-check component references on the board against the drawing before replacing parts.
