RAR archive labelled for the Wistron-built HP ProBook S-Class Intel platform, covering the 4720s and 4520s models. The name does not say whether it holds a schematic, a boardview or both, so open it and check the contents before planning a repair. Wistron designed these ProBooks for HP, and its documents are the reference for tracing power rails, charger and EC circuits and the signal paths around the Intel chipset. Compare the board number and revision silkscreened on the PCB with the document before trusting any part designation.
