Dell archive labelled 6400 with board code FM1 and revision R1A, 959 KB in RAR format. The name suggests the Inspiron 6400, though only the number 6400 is stated. FM1 follows a Quanta-style project code. Contents are likely a schematic for tracing power rails, checking the charging circuit and locating components during no-power or no-display repair. Verify that FM1 and R1A match the markings on your motherboard before relying on part designators or rail values.
