Schematic in PDF format for the Lenovo ThinkPad A285, an AMD-based model, on the LCFC board NM-B751. LCFC, Lenovo's own ODM, uses NM-xxxx board numbers. The 2.93 MB document lets a technician follow power rails, the power-on sequence, charger circuits and signal paths across the sheets. It also gives component values and reference designators, which help when replacing parts. Open it in any PDF reader, ideally next to a boardview, and confirm the NM number on your board.
