Schematic for the Quanta FM9 discrete-graphics motherboard, revision 2B, dated 2 June 2009, provided as a PDF in RAR. Discrete means the board carries a dedicated GPU with its own power stage and video memory, which the UMA FM9B sheets lack. The laptop brand is not stated. Technicians use it to troubleshoot GPU core and memory rails, trace display signals and check power sequencing. Verify the PCB is FM9 rev 2B, since earlier 1A versions of this schematic are also around.
