Quanta BQ2L board package in a 1.15 MB RAR. Quanta is an ODM that labels its notebook projects with short alphanumeric codes such as BQ2L, but the name does not say which brand or retail model used this board, nor its revision. The archive most likely holds schematic pages. Confirm the code on the PCB silkscreen before relying on it, then use the pages to follow the DC-in path, charger, system rails and EC power sequence, or to locate parts around a shorted line.
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.
