Archive for the HP Pavilion dv6 and dv7 series built on a Wistron board, with 11A39-2 as the platform or project reference given in the name. At 1.06 MB in RAR format it probably contains a schematic or a firmware image. Wistron designed many Pavilion motherboards, and its schematics help with tracing rails, locating power-sequence signals and finding test points. Make sure the board identifier printed on your PCB matches the 11A39 reference before relying on any of the data.
