Archive for the HP Pavilion dv4 with an Intel Core i3 processor, referencing board 4106P, likely the Compal LA-4106P mainboard. Size is 1.74 MB in RAR format. Compal numbers its laptop boards LA-xxxxP, and the full code with revision is printed on the PCB, so read it before use. Contents are probably schematic and possibly boardview data. These are used to trace rails, inspect the power-on sequence and find components behind no-power or no-display faults.
