Quanta N69A motherboard documentation, board number DAN69AMB6D0 at revision 1A, stored in a 1.31 MB RAR archive that most likely contains the schematic. No brand or retail model appears in the name, so identify the machine from the PCB markings. Quanta codes its boards with a DA prefix followed by the project name, which makes the silkscreen the easiest way to match the file. Use it for following power sequencing, locating the source of a shorted rail and checking component values around the charger and VRM stages.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
