Schematic archive for the Dell 1720 laptop, labelled FM5 in the name, likely the motherboard project code, in a 1.43 MB RAR file. A schematic shows circuit blocks, power rails, signal names and component values, so you can follow the power-on sequence and find what feeds a missing voltage. Schematics are usually PDFs, opened in any PDF reader. Before relying on component values, confirm that the board code printed on the PCB matches FM5, since Dell models can ship with different boards.
