Boardview for the ASUS PU551JA laptop, main board 60NB07B0-MB1200 revision 2.0, in a compact ZIP archive. The 60NB-prefixed number is ASUS's own part numbering for motherboards. Open the extracted file in a boardview program such as OpenBoardView or FlexBV to locate components, test points and nets while tracing a power rail or isolating a short. Check that both the part number on the sticker and the R2.0 revision on the PCB match before relying on placements.
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 @cynetitsolution. Enginerys does not host this file.
