Schematic for the Lenovo NM-A191 mainboard, a PDF inside a RAR archive of 1003 KB. NM-numbered boards are LCFC designs, the ODM owned by Lenovo. Use it to follow rails from the DC jack and charger to the CPU, memory and chipset supplies, to trace enable and power-good signals and to check component values near a short. The revision is not stated in the name, so verify the number and revision silkscreened on the board before replacing anything based on these pages.
