Hi xymxppl ,
Welcome to the Community Forums.
Schematics (internal use) for specific systemboard are not available for document download from the support site. As such, board level repair are not done instead the entire motherboard are being changed.
You may check specific systemboard part number that came with your machine from the parts look up page ("Interactive schematic not available for this product") . Herewith are the hardware manual (FRU list on item 5 page 73-75).
