Compal LA-1931 schematics, revision R0.3B, compressed into a 1.24 MB RAR file. The B suffix marks a sub-revision of R0.3, one of several engineering stages before the R1.0 release of this board. The name lists no laptop model or chipset; the LA- code is Compal's ODM board number. A technician can trace rails, compare expected voltages and locate the component behind a short. Confirm that the PCB carries this exact revision, or at least a close one, before trusting component values.
