Schematic archive for the Lenovo ThinkPad L420 using Quanta board DAGC9EMB8E0, revision E, delivered as an 804 KB RAR. Quanta mainboards carry DA-prefixed part numbers in which the middle letters give the project code, here GC9. The diagrams help you follow the power-on sequence, check the charger and core regulators, identify components around a short and locate test points for measurements. Confirm that both the DA number and the revision letter printed on your board agree with this document before replacing parts based on it.
