Schematic for the Lenovo ThinkPad E43L, Quanta LE9E mainboard, revision 1A, in a 1.28 MB PDF. Quanta boards carry a short code like LE9E on the PCB, and comparing it with the revision is the first step before using the drawing. A technician relies on these pages to trace power rails from the DC input onwards, look up resistor and capacitor values, find test points and narrow down the component responsible for a short, missing voltage or no-boot condition. Any PDF viewer opens it.
