Schematic for the Compal LA-B651P motherboard, revision R0.2, compressed into a 1.55 MB RAR. Compal's newer numbering uses a letter after LA-, as here, and these boards go into laptops of multiple brands. R0.2 is an engineering revision, so verify part values and placement on the real board. The PDF helps trace the power chain from adapter input through charger and regulators, check sequencing and enable signals and find components on a shorted rail. Match the LA code and revision on the PCB before relying on it.
