This is a Lenovo Thinkpad P15s Gen 2 with a board NM-D351. I'm having trouble finding my dead short to ground. I have the area narrowed down after much probing. You'll see in the boardview, there are two coils involved. I removed those coils and verified that that short is not on the mosfet side of those coils. . You'll see an arrangement on both sides of the board of 5 caps and one smaller one to the side. I have removed ALL 12 of these small caps and still have the short. Prior to that I injected at those caps with 1v5a and the short was only drawing 800ma so I could not see anything on thermal.
