First, I want to thank anyone who has taken the time to look at my post.
I have a Lenovo ideaPad 3 17IIL05. Board ID: GS454/GS554/GV450/GV550/HS750 Rev 1.0 NM-D031. Intel i5 (10th gen) with 4GB onboard SK Hynix modules.- I've found memtest86 v11.5 is showing the onboard RAM is failing.
- I've attempted to use the following schematic to disable the onboard RAM: nm-d031
- I moved resistors RC826 to RC839, RC827 to RC840, and RC828 to RC841.

During a board-level inspection, I found that the replacement board is missing the following components:
