Compal LA-4501P schematic in a 586 KB RAR, with revision 1 in the name. Compal, a major notebook ODM, uses the LA-xxxxP format for its board numbers, which appear on the PCB silkscreen and are shared across several laptop brands. The document lets you trace power rails, follow the power-on sequence, locate components by reference and find test points. Extract the PDF with WinRAR or 7-Zip, then confirm the LA number and revision printed on the board agree before relying on component values.
