Schematic for the HP ProBook 4520s, based on the Intel Calpella platform, delivered as a 1.93 MB PDF. The name also mentions S-class and Intel 10282 with tokens like PVRT and LAN that look like the project or schematic title, so check the title block for details. Engineers use these pages to trace power rails, debug the power-on sequence, find the source of a short and follow signals across chipset, EC and connectors. Make sure the board revision in the document matches your PCB before taking measurements.
