Package for the HP Pavilion DV4 and Compaq Presario CQ40 and CQ45 laptops, Intel platform with discrete graphics, built on Compal board LA-4102P. Compal is the ODM that uses the LA-xxxxP numbering printed on its PCBs. The 1.64 MB archive most likely contains the schematic, useful for tracing the GPU power rails, charger, EC and sequencing signals. Since these models also had integrated-graphics versions on other boards, confirm a dedicated GPU is fitted and the LA number matches before relying on it.
