Boardview for the AT6-D motherboard, a variant of the Quanta AT6 platform used in HP Pavilion DV6000 laptops, provided as a .BRD file in a 166 KB RAR. The D suffix denotes a separate design variant, so it should not be swapped with plain AT6 files. Use it to find components, connectors and test points and to follow nets when hunting a short or missing voltage. Open it with OpenBoardView or FlexBV, and confirm the board marking on the PCB matches AT6-D before probing.
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 @schematicslaptop. Enginerys does not host this file.
