Clevo boardview for the V255RNB2, V255RNC2 and V255RND2 laptop chassis, with PCB number 6-71-V2700-D02 in the name, where the trailing D02 suggests the board revision. The 9.77 MB RAR archive probably holds a detailed layout or several related files. Clevo prints 6-71 numbers on the board itself, so compare it with the marking on your PCB before use. In a boardview viewer the file helps you locate components, follow nets and pick test points when tracing power faults.
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 @BoardSchematic. Enginerys does not host this file.
