PDF schematic for the Quanta UM3B and UM6B boards, which the name ties to the Dell 1464 laptop. One document covers both project codes, so pages may note which components fit each variant. Quanta designs and builds many Dell notebooks, and the UM code printed on the PCB identifies the board more reliably than the sticker. The drawings help trace the charger and system power rails, find the source of a short and identify parts around the EC. Check the board code before trusting a component value.
