Schematic in PDF form for the Quanta HKA mainboard, packed in a 1011 KB RAR archive. HKA is a Quanta project code; the name gives no laptop brand, board revision or full board number. Use it to trace power rails, follow enable and power-good signals, locate the charging circuit and identify components around a short. Open it in any PDF reader after extraction. Compare the project code and revision printed on the PCB with the schematic title block to make sure the document applies.
