PDF schematic for the Dell OptiPlex 3070 Micro form factor desktop, project D9.5 MFF, labelled COUGAR MLK at revision A00, archived as a 2.40 MB RAR. Opened in a PDF viewer, it lets a technician follow the standby and main power rails and the power-button and reset logic, and check connector pinouts when fixing a no-power or no-POST unit. Cross-check the revision on the board before trusting component values, because Dell small form factor boards can change between revisions.
