ZIP archive of 2.16 MB labelled for the HP Pavilion dv5 line with the code QT6, which matches a Quanta platform name used on dv5 boards. The name does not say whether it holds a schematic, boardview or BIOS, so extract and inspect it. Quanta platform codes appear on the PCB silkscreen, often as part of the DA board number. Confirm the code and revision on your board match QT6 before using the material to trace rails, find test points or reflash firmware.
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 @cyberlanelectonik. Enginerys does not host this file.
