Dell 3421 and 5421 service package for the OAK14 board, Chief River platform, discrete graphics version, revision A00, packed as a 1.91 MB RAR. Chief River is Intel's mobile platform code name for the Ivy Bridge generation. A schematic like this helps trace CPU, GPU and memory rails, check power sequencing and locate shorts. Since both models share the board, confirm your PCB carries the OAK14 marking and the discrete GPU section before working from it.
