Compal LA-1452 laptop board schematics at revision R1.0, compressed into a RAR archive of 915 KB. Other revisions of the same board, such as R0.2 and R1C, also exist and can differ in component values, so check the silkscreen revision before use. Compal designs and builds notebook mainboards for many brands and identifies them with LA- numbers. The extracted sheets let a technician follow the power-up sequence, identify regulators, fuses and MOSFETs, and measure expected voltages to isolate a failing circuit.
