Archive covering the Dell Latitude D420 and its Compal LA-3071P motherboard, packed as a 1.28 MB RAR file. The name does not state the revision, so check the silkscreen near the board code before using it against your unit. Compal uses the LA-number pattern for boards it builds for Dell and other brands, and service documents for them are usually PDF schematics. A technician would use them to trace rails from the DC jack through the charger and regulators, find test points and isolate shorted components on this compact ultraportable.
