Schematic in PDF form for the Wistron DL340-HSW platform, board number 13221-SA, with the name pointing out the TI bq24715 battery charger controller. HSW most likely refers to an Intel Haswell design. Wistron builds boards for several laptop brands, so the platform name is often more useful than the retail model when searching. Technicians use such diagrams to trace power rails, follow the charging circuit around the bq24715 and locate components when diagnosing no-power or no-charge faults. Check that the PCB number and revision match.
