The code 113cnq080a is the only detail in the name of this 194 KB PDF, filed as a schematic with no laptop model, board or revision. It reads like a dual Schottky rectifier part number with a voltage grade and letter variant, so the document most likely gives ratings, curves and outline dimensions. A standard PDF viewer opens it. Use it to confirm a replacement matches reverse voltage and current capability, and check the trailing letter on the part, as variants may differ in package.
