Repair material for the HP Pavilion dv4 / Compaq CQ40 with AMD discrete graphics, based on Compal board LA-4112P at revision 0.1, in a 988 KB RAR archive. Compal uses the LA-xxxxP pattern for its laptop mainboards, and the number is printed on the PCB itself. Use the schematic to check the GPU power rails, the charger stage and the always-on supplies when chasing a short. An early 0.1 revision may differ from production boards, so verify the component values against the actual board.
