Circuit diagram for the Quanta UM7 motherboard, UMA version, revision 1A, supplied as a PDF of 677 KB. UMA means graphics are integrated in the processor, so there are no dedicated GPU or VRAM sections to look for. Quanta is a contract manufacturer and its project codes rarely match the retail model name. Technicians open this in any PDF viewer to follow power sequencing, check rail resistance to ground and find part values. Make sure the board is actually a UM7 at rev 1A, since other revisions can differ.
