Boardview file in WPH format, about 2 MB, labelled JE70D119. The code looks like a board project identifier, yet the name does not state the laptop brand, model or revision, so compare it with the silkscreen markings on the PCB. WPH boardviews open in viewers such as Boardview software that read this layout format and show component placement, part references, nets and test points on both sides of the board. They help locate a shorted capacitor, follow a power rail or find a probe point without the full schematic.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @bios_laptop. Enginerys does not host this file.
