About schematics
A schematic is the electrical drawing of a board: it shows how every chip, MOSFET, coil and connector is wired, which rail feeds which circuit, and what voltage or resistance you should measure at each test point. It is the document you need to trace a missing rail or a short.
Schematics are published per board, not per laptop model. The same Compal LA-E891P board can sit in several HP models, so always search by the board number printed on the PCB rather than by the sticker on the case.
