HP notebook boardview built on a Quanta motherboard, number DAN91AMB6D0, project N91A, delivered as a 1003 KB .bdv file. Quanta encodes its project code inside DA-style board numbers, with the trailing characters indicating the board revision, so the code on the PCB should match exactly. Use the file to locate parts and test points, follow signals between chips and check suspect rails for shorts. It can be opened in Boardviewer, FlexBV or similar boardview software.
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 @boardviews. Enginerys does not host this file.
