Full schematic set for the Compal LA-E541P motherboard at revision 2.A, covering project codes DIUYA, YB, SA, SB and SD, delivered as a 2.04 MB PDF in a RAR archive. Compal marks its main logic boards with the LA prefix, and these numbers often sit under other brands' laptops. The diagram helps you follow power rails from the charger input through to CPU core, track power sequencing signals and find the parts behind a shorted rail. Make sure the revision silkscreened on the PCB agrees with 2.A, as layouts change between revisions.
