Schematic for the HP EliteBook 2530p, Compal board LA-4021P with platform code JAT00, in a 1.08 MB RAR. Circuit diagrams like this let a technician follow the power sequence, trace charger and standby rails, check signal paths and read part values when diagnosing a dead or shorted board. LA-xxxxP is Compal ODM numbering. The document is usually a PDF; check that the board number on the PCB matches LA-4021P before relying on component references.
