Archive for Compal mainboard LA-3331P, revision 1A, with a date tag of 0620 in the name. No laptop brand or model is stated, since Compal LA codes identify the ODM design rather than the retail product. At 2.33 MB it may contain a schematic plus additional files, but the exact contents are unconfirmed. Extract it with WinRAR or 7-Zip, verify the LA number and revision printed on the PCB, then use the material to follow power rails, locate components and check suspected shorts.
