Boardview for the Lenovo ThinkPad-class L540 laptop, tied to board number 12290-1, a numbering pattern associated with Wistron as the ODM rather than LCFC. At only 154 KB the ZIP probably holds a single layout file without schematics. Load it in a boardview viewer such as OpenBoardView or FlexBV to find component locations, check which parts share a net and choose test points while diagnosing no-power or charging faults. Confirm the 12290-1 number on your mainboard, because the L540 may have shipped with different board variants.
