Lenovo E40 schematic from Quanta, describing the LD-NOTE board with UMA integrated graphics and titled Diamond-3 for the Intel Calpella platform, packaged as a 799 KB PDF. Calpella is Intel's code name for its first-generation Core i platform with the HM55-class chipsets. Use the drawing to trace power sequencing, memory and display signals, and to find the source of a short or a missing voltage. Make sure the PCB is the UMA build and not a discrete-graphics variant, since the pages for the graphics section differ.
