Service archive for the HP Compaq Presario CQ40 AMD version, based on the Compal LA-4112P mainboard, in a 1.16 MB RAR file. Compal applies the LA-xxxxP pattern to the laptop boards it builds for HP, and the CQ40 was produced on several such boards for Intel and AMD variants. Read the LA number and revision on the PCB to confirm the match. Schematic pages support tracing power rails, checking the power-on sequence and locating shorted parts.
