Compal LA-2491 motherboard documentation at revision 1.A, packed as a 1.89 MB RAR archive. The name does not list the contents, but archives named this way usually hold the laptop schematic in PDF form, sometimes with a boardview. Compal is a Taiwanese ODM that builds notebooks for many brands, and its LA- codes are printed on the PCB itself. Extract with WinRAR or 7-Zip, then confirm the board number and revision silkscreened near the edge match before tracing rails or replacing parts.
