RAR archive of service material for the ASUS FA608UP laptop, with the name pointing to a Quanta-built mainboard carrying the NJWI project code. The name does not say whether it holds a schematic, a boardview, a BIOS dump or a mix, so expect to unpack the 21.6 MB archive and sort the contents yourself. Quanta designs many ASUS gaming boards, and its project codes help match documents to the right PCB. Check the board number and revision silkscreened on the PCB against whatever is inside before tracing rails or flashing anything.
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 @boardsscanrepo. Enginerys does not host this file.
