MSI schematic in PDF for board MS-14B2 version 0A, with sub-board MS-14B21 revision A. MSI names laptop mainboards MS-xxxx, and daughterboards add a digit, so the second number likely covers a secondary board in the same set. Version 0A suggests an early design revision, so compare it with the version printed on your PCB. Use it to follow power sequencing, check component values and trace signals between boards.
