BDV boardview for a board labelled LX6-MB-I, about 1.12 MB; no brand, laptop model or revision is given beyond that code. A boardview like this shows both sides of the PCB with component outlines and nets, so you can click a pin and see every connected point, which is handy for finding shorts to ground or following a signal between chips. Open it in FlexBV or a compatible boardview viewer, and make sure the silkscreen on your board reads LX6-MB-I first.
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 @pepeelectronica. Enginerys does not host this file.
