Labelled 40CPQ050, this 55.8 KB PDF is listed as a schematic but the name resembles a semiconductor part number and carries no laptop model, brand or board revision. Treat it as a component reference sheet. When a part on a power stage fails short, a sheet like this helps you identify the pins, check the package and choose a correctly rated substitute. Read it in a standard PDF viewer and make sure the last digits of the marking on your component are identical, as the numeric suffix normally separates variants of a series.
