Laptop schematic for the Lenovo E47, built on a Quanta board with the project code KL9A, packed in a 1003 KB RAR archive. Quanta names its laptop projects with short letter-and-digit codes like this, and the same code is usually printed on the PCB next to the board revision. Technicians use such diagrams to follow power rails from the charger input through the standby and main regulators, to identify components near a short and to check signals between the chipset and the EC. Confirm that the board on the bench carries the KL9A marking first.
