Schematic PDF for a board called MANAUS 10AD, 503 KB. Manaus is an Inventec project name, with Manaus 10 boards used in Toshiba Satellite notebooks, but the name does not give the exact laptop model, board number or revision, so read the title block and compare with the 6050A code printed on the PCB.
