Quanta JM7B board documentation in a 1.37 MB RAR archive, marked as the discrete graphics version at revision 2B. The discrete tag separates it from integrated-graphics builds of the same platform, which differ in GPU power circuitry and VRAM layout. A technician would use the material to follow GPU core and memory rails, check for shorts and locate key components. Quanta sells boards to several notebook brands, so match the JM7B code and 2B revision printed on the PCB before trusting values.
