Schematic for the MS-A9531 board, version 1.0, provided as a PDF compressed in a RAR archive. The MS- prefix is the numbering used by MSI for its motherboards, so this covers that MSI board design. The diagram lets you trace power rails, signal paths and component values while diagnosing no-power, no-display or charging faults. Note that a 1.2 version of the same board also exists, so verify the revision printed on the PCB before trusting the circuit details in this 1.0 set.
