PDF schematic for MSI laptop board MS-17221, revision 1.0, packed into a 1.27 MB RAR. It documents power rails, the power-on sequence, charger, memory and display circuitry for this in-house MSI design. A technician reads it to see which rail is missing, which enable signal starts each regulator, and what values replacement parts need. It pairs with the MS-17221 boardview for physical locations. Confirm the revision on the PCB, since later revisions may change parts.
