Schematic for the Lenovo Z360 laptop built on the LL7A board, covering the discrete graphics version at revision 1A, in PDF form. LL7A follows the short project-code style used by Quanta, which manufactured this board. Check that the PCB carries the same code and revision, and that your unit actually has the dedicated GPU. The diagrams help trace GPU and CPU power rails, verify the power-on sequence, and locate components around a short. Opens in any PDF reader.
