Compal LA-1901 schematics at revision R3.0, a 1.42 MB RAR archive. R3.0 is a late revision, newer than the R1.0 document also listed for this board, and likely reflects later design changes. The name does not give a brand or chipset; LA- is Compal's ODM board code. Technicians use these drawings to trace the power sequence, measure rails at test points and pinpoint shorted parts. Unpack with WinRAR or 7-Zip, then confirm the PCB shows revision 3.0 before relying on part values.
