Quanta Volks schematic for a 14-inch AMD Comal platform at revision 1A, a 1.43 MB PDF. The name marks it as covering both DIS and UMA builds, meaning versions with a discrete GPU and with integrated graphics only, so check which sections apply to your board. No brand or board number is stated. Use it to follow power rails, check the GPU power stage on discrete units, verify connector pinouts and trace shorts. Match the project name and revision printed on the mainboard before relying on values.
