Quanta ZHK mainboard schematic set, revision 1A, identified by the board number DA0ZHKMB6C0, in a 781 KB RAR file. The name does not say which laptop model uses this board. In Quanta numbering, the DA0 prefix plus project code and MB suffix marks the bare motherboard PCB, and the final characters reflect the PCB version. Use the drawings to trace power rails, locate the EC and SPI BIOS chip, and diagnose no-power faults, after confirming the printed number on the board is the same.
