ASUS Vivobook M1502YA motherboard archive for revision R2.0, a RAR of about 128 KB. The name does not say what is inside, though the small size points toward a boardview or compact service file rather than a full BIOS or schematic. Extract it to check the contents, and confirm the PCB is marked M1502YA R2.0. If it is a boardview, open it in a boardview viewer to locate components, trace nets and find test points when diagnosing power faults on this laptop.
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 @smschematics. Enginerys does not host this file.
