Compal schematics for motherboard LA-2491 at revision R1.0, delivered as a 1.10 MB RAR archive. This four-digit LA code belongs to an older generation of Compal notebook boards, and the name does not say which brand or model used it. Extract the archive and open the document to study the power distribution, follow the power button and EC logic, measure rails against expected values, and find components connected to a short. Make sure the code and revision printed on your PCB match LA-2491 R1.0 before relying on part values.
