Compal LA-1281 schematic set at revision R2A, stored in a 1.18 MB RAR archive. It belongs to an early generation of Compal laptop boards and documents power rails, signal routing and component values. Use it to trace missing voltages, check power sequencing and pinpoint the component behind a fault. Another release, R1.0, exists for the same board number, so read the revision silkscreened on the PCB before choosing which document to follow, since parts may have changed between releases.
