Schematic for a Dell Inspiron Z series laptop on the AMD platform, supplied as a 744 KB PDF. The name does not give the exact model number, board number or ODM, so identification has to come from the title blocks inside the document. A technician uses such drawings to follow power rails, check the charging and regulator stages, find test points and trace a short. Open it in any PDF reader and compare the board number on the PCB with the one shown in the schematic before trusting values.
