Filed as a schematic, this 271 KB PDF is named after the discrete part number 2N5684 with an unexplained RE suffix, which may indicate a reissued edition. No laptop model, board number or revision appears in the name. Under the JEDEC 2N scheme the document is almost certainly a component datasheet covering pin layout, package outline and electrical characteristics. Use it to check orientation and ratings when replacing the device, and compare the marking on the original part to be sure the right sheet is in hand.
