Service material for the Lenovo E20 laptop on Compal board LA-3541P, supplied as a 916 KB RAR archive. Compal mainboards use the LA-xxxxP numbering, and that code is printed on the PCB together with a revision, so matching it is the first check. A schematic for this board lets a technician trace the DC-in and charger circuit, the CPU core and memory rails and the power-on signal chain. It also helps locate test points and parts around a shorted line. Extract it with WinRAR or 7-Zip; the name does not list the exact file types inside.
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.
