Catalogued as a schematic, this 27.2 KB PDF carries only the code 3LP01SS, which looks like a component part number with a two-letter SS suffix. No laptop model, brand or motherboard number is stated. Files of this kind usually hold a few pages of electrical ratings, pin assignment and outline dimensions. Use it to check a suspect part found near a power rail, read its pin layout before measuring with a multimeter, and compare the full suffix on the package, since suffix letters often separate variants.
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 @cyberlanelectonik. Enginerys does not host this file.
