Schematic in PDF form for the Lenovo E420 and E520, project LGG1, motherboard 10292, the companion to the boardview of the same name. It documents power sequencing, voltage regulators, the EC, the charging circuit and the signal paths between major chips. Use it to identify which rail is shorted, what voltage a test point should read, and which enable signals a regulator needs. Confirm the PCB markings match the LGG1 10292 design, since later revisions can change parts and net names.
