Labelled 100mt160p, this 90.2 KB PDF is filed as a schematic though its title resembles a component part number, not a motherboard designation. No laptop brand, model, board number or revision appears in the name. A sheet like this is normally consulted for terminal identification, voltage and current limits and the package outline when a power stage component is suspect or a substitute is needed. Any PDF reader will display it. Check the stamped marking on the actual part matches before relying on values.
