Dell 700M service material packed as a RAR archive of 819 KB. The name holds no board number, ODM code or revision, so the exact contents, most likely a schematic, need checking after extraction. A technician uses this kind of document to trace voltages, find the charger and system regulator circuits, and locate pads for measuring resistance to ground when hunting a short. Compare the board number printed on the PCB with the drawing title block before relying on any values or part locations.
