Hi @eric27347
I can't find a free download online but ***''if''*** the motherboard model number is NM-D031 (printed on motherboard) then here's a link to a [https://realschematic.com/shop/11132/desc/lenovo-ideapad-3-15iil05|supplier] of a schematic for the board.
It shows all the component types and values etc.
It's cheap enough to buy if you can't find a free download.
If it is not the board number of your laptop, search online for ''(insert motherboard's board number) schematics'' to hopefully find suppliers or free downloads.
