Circuit diagram for the Lenovo M5400 laptop, drawn for the board numbered DA0BM8D0 at revision D. A DA0-style number is normally printed on the bare PCB itself, so check the silkscreen to confirm the board and revision before following the pages. Technicians use a schematic like this to trace power sequencing, find the controller behind a dead rail and check the values of passive parts around a shorted line. It opens in any ordinary PDF viewer. Differences between board revisions can move or rename parts, so match the revision letter as well.
