This guide documents fault diagnosis for the '''[[IBM PS/2 Model 70]]''' (machine type 8570, all submodels). The Model 70 shares much of its POST architecture with the [[IBM PS/2 Model 50]] / [[IBM PS/2 Model 60|60]] but has 80386DX-specific and Power Platform-specific failure modes, and is uniquely afflicted by the SMD electrolyte leakage that defines the PS/2 plague.
