Compal LA-4117P laptop motherboard schematic at revision 0.3, a 2.39 MB PDF. Compal, a large Taiwanese ODM, prints LA-xxxxP numbers on its boards, and the same board can appear in machines sold under different brands. The diagram is useful for tracing power rails from the DC jack through the charger and regulators, locating the EC and BIOS chip, and checking signals during no-power or no-display faults. Revision 0.3 is an early issue, so verify the LA number and revision on the PCB before relying on values.
