PDF schematic labelled Z94Rp, with no revision, brand or laptop model in the name. Open it and read the title block to find the revision, then compare it with the markings on the motherboard, since other Z94 revisions also circulate. Circuit diagrams of this kind are used to trace power rails from the adapter input onward, confirm which controller generates each voltage, and identify components to test when a rail reads low or shorted to ground. Any PDF viewer with search makes net lookups faster.
