Archive for board LA-6591 with the PAL5X project code, marked UMA for integrated graphics only, plus the Macallan 14 UM label, in a 1.66 MB RAR. The LA- prefix matches Compal numbering. UMA versions omit discrete GPU circuitry, so a discrete board will differ. Check the board number and revision on your PCB first. The schematic helps trace rails, locate test points, follow the power-on sequence and isolate shorts around the charger and CPU regulators.
