Schematic for the HP ProBook 4520s, referenced in the name as H9265-1, supplied as a PDF in a RAR archive. It lets a technician trace power rails, the charging circuit, the standby supplies and the CPU and chipset signals page by page, and find component designators for measuring and replacing parts. Open it with any PDF viewer once extracted. Several board variants were made for this model, so confirm the board identifier printed on the PCB matches before trusting values or net names.
