Schematic in a 1.85 MB rar archive for the Compal LA-K093P board, revision 1B, listed for an Acer notebook. Compal is the ODM behind the LA-xxxxP numbering, so the code on the PCB identifies the board regardless of the laptop model it ends up in. The diagram helps trace power sequencing, measure rails, locate a shorted line and verify part values. Extract the archive first, and make sure the board number and revision silkscreened on the motherboard match r1B before relying on the drawings.
