PDF schematic for the Dell Inspiron 660 and Vostro 270 desktops, which share Wistron mainboard 11068-1. The 3.97 MB RAR contains the circuit diagram for following standby and main power rails, the reset and power-good chain, and connector pinouts. Wistron uses the five-digit plus dash number pattern for its boards. Check that the number printed on the board matches before relying on the component values. Pair it with the matching boardview to find parts physically.
