PDF schematic for the BOLT-L project in UMA form with integrated graphics only, carrying Wistron board numbers 17938-1 and 18790-1, with FW8G6 likely a part number and REF marking a reference design. The five-digit-dash-digit pattern is Wistron's board numbering, often used on Dell machines. The document helps trace rails, signals and component values during diagnosis. It opens in any PDF viewer. Match the number on the PCB, as UMA and discrete versions differ in circuitry.
