Compal schematic in PDF for the FH50P project, board number LA-H901P at revision 1A. The LA-xxxxP pattern is Compal's own motherboard numbering, and the laptop brand that sold the machine may be different. The diagram lets a technician follow power rails from the charger and PWM controllers to the CPU and memory, read the power-on sequence and identify signal names for measurements. Match the LA-H901P label and the revision silkscreened on the board before working from these pages.
